In general, many aquarists will notice a white film start to grow over their driftwood in a newly set up fish tank. This film is completely harmless to your livestock. It is made up of bacterial fungus and can be removed manually using a toothbrush.

This white film is made from a mix of harmless fungus and bacteria. Sometimes, people think it is a white algae invasion, algae growth, white mold, or dead algae turn white.

But it’s commonly referred to as biofilm…

It’s very common for biofilm to grow on new driftwood within an aquarium. Check out this post to learn all about biofilm on aquarium wood.

The good news is that what looks like white algae growth is just biofilm. And biofilm is harmless and easy to get rid of. Below, I’ll share with you what causes this film to grow and the easiest way to remove it from your fish tank…

Causes For White Film On Driftwood In Fish Tank

Aquarium owners know that you need the right water and tank conditions for something to grow…

Poor water quality, too much fish waste, uneaten food residue, not enough beneficial bacteria, an unbalanced tank, low light penetration, or other issues can cause lots of unwanted things to start growing…

For example, some algae thrive in some of these conditions…

But this isn’t the case for the white stuff growing on your driftwood…

You can have perfect water parameters, do regular water changes, and keep your tank clean of dirt and debris, but you may still have this white fuzz/white fungus-looking substance take over your driftwood…

And don’t worry; this is completely normal, especially if you just recently placed new driftwood into your fish tank.

You see, the main cause for this white cottony growth all over your driftwood is the driftwood itself.

Driftwood and other types of aquarium woods will start leeching nutrients and carbohydrates into the water column…

This creates the perfect environment for microorganisms, harmless fungus, and bacteria to start forming on the surface of your driftwood. (1)

This is why it’s so common for a white film to start growing on driftwood within new tanks. But it’s easy to get rid of, and over time, this film will stop forming as the nutrients from the driftwood get depleted.

In most cases, some aquarists soak driftwood in water for weeks and rinse their wood until it stops forming this white algae growth-looking film. Others resort to boiling to try and remove as many of the nutrients as possible before placing the wood into their tanks.

Is The White Film On Driftwood Harmful To My Fish Tank

The good news is this unsightly film is harmless to your fish and other livestock in your aquariums.

In fact, some shrimp keepers actually grow this film on purpose in order to feed their shrimp colonies.

But there is no immediate danger to having this in your aquariums…

I’ve even personally seen my guppies pick and eat this film in my own aquarium.

But even though this film is harmless to livestock, your aquatic plants are a different story.

I made the mistake of not doing a good job cleaning up this biofilm after scrapping it off of my hardscape.

It fell onto my carpet of dwarf hair grass. I noticed the areas where the biofilm had fallen on started to melt and die off.

So keep this in mind if you have plants in your aquariums.

How To Get Rid Of This White Fuzzy Stuff On My Driftwood

Keeping your tank clean from this white mold-looking stuff is pretty straightforward. You can either use an old toothbrush to scrub off the white film off of your driftwood.

Or you can hire the help of a clean-up crew in order to eat this white algae-looking growth off of your hardscape.

There are a few people who recommend using aquarium-safe chemicals like hydrogen peroxide to get rid of this, but I find that a little too harsh just for removing biofilm since it generally disappears over time anyway…

Manually Removing What Looks Like White Algae Growth

This is simple simply scrub the infected areas with a toothbrush. This will knock the film loose, and it may start floating around your aquarium.

Make sure to remove your white film during water changes so you can siphon these chunks out of your tank right away.

If you do this regularly, then over time, the film should stop forming once your driftwood has had all its nutrients depleted.

Using Algae Eating Fish Or A Cleanup Crew To Do The Job

Another option, and my preferred method, is to just have your clean-up crew do the job for you.

I think every aquarium should have a clean-up crew in order to maintain a healthy and balanced ecosystem for your fish.

Also, having your fish do the work for you isn’t all that bad…

You can use any algae-eating fish like plecos or otocinclus catfish.

You can also use shrimp (biofilm is one of their favorite things to eat) or nerite snails to do all the clean-up work for you.

Final Thoughts On White Film Growth In My Fish Tank

This wraps up my post on white film growth on driftwood.

If you see a clear substance that looks slimy, then chances are you are dealing with biofilm growth on your driftwood.

This is great news since it’s usually just an unsightly eyesore and poses no danger to the creatures living in your aquarium.

Also, this film is easy to remove and goes away with some time.

I hope I was able to put your mind at ease and help you with any questions you had about this topic.

Thanks again for taking the time to read this post, and I hope to catch you in another one!

The post What’s The White Film On The Driftwood In My Fish Tank first appeared on All Blue Aquatics.

In general, getting rid of biofilm on your aquarium’s surface is very easy. You can use surface skimmers, create more surface agitation, or manually remove this protein film with a paper towel. Once you remove the surface scum, you will want to investigate the root cause of the issue.

This surface scum is sometimes referred to as biofilm or protein film and can look like an oil slick has formed on top of the water of your fish tank.

It’s easy to take care of, and you usually won’t run into this issue if you are running a surface skimmer or a filter with a built-in skimmer.

My recommended filter with a built-in skimmer is the Tidal HOB filter. You can check the prices on Amazon here.

But if you don’t have a protein skimmer or a good amount of water movement on the surface of your aquarium, then a thick layer of oily film can start to form.

Below, I’ll talk about what causes this oil film to start forming, whether you should be concerned about it, and how to remove this film from the surface of your aquarium water…

What Causes Oily Film To Form On Top Of Fish Tank Water Surface

The formation of biofilm (also referred to as protein films, oil films, oil slicks, surface scum, etc) is from the build-up of microorganisms on top of the water surface.

These microorganisms feed on the organic wastes within your aquarium water.

It’s completely normal to get a small build-up of this film on the surface of your fish tanks. This is especially true if you have low surface agitation and are not running a skimmer.

But if you find yourself dealing with a thick layer of this stuff and dealing with a constant battle with this surface scum, then you need to lower the organic wastes being built up within your fish tank.

This can also be a sign of poor water quality within your tank. (Unnatural thick layers of oily film, bubbly water, or a strong foul odor. Can be signs of an underlying issue within your fish tank.)

Here are the common reasons why you may have an abundance of surface scum on top of your aquarium water…

Too Much Fish Food Left Uneaten

A common reason the water surface of your aquarium may start to look like an oil slick accident has just happened is because of overfeeding your fish food and not cleaning up the uneaten fish food left behind.

If you tend to go a little overboard during feeding time, then lots of uneaten fish food can slowly build up within your tank, causing the perfect environment for oily films to start from the top of your tank.

Decaying Dead Fish Somewhere In The Tank

I get it…

Sometimes, it can be hard to notice a dead fish in your fish tank, especially if you have nooks and crannies where only your fish can go in and out.

But if you leave the bodies of your dead fish to rot and decompose in your tank, it can cause lots of unwanted problems down the road.

A build-up of surface scum is the least of your problems…

Dead fish can cause a spike in ammonia, and your tank cycle can crash, leading to other problems.

Too Much Fish Waste Building Up Within Your Fish Tank

This sort of goes hand in hand with over-feeding your fish. But if you let fish poop build up in your tank, then this is another reason why an oil film or protein film can start forming.

If you are overfeeding fish food, this will cause your fish to produce more fish poop.

Also, if you skip your water change or just don’t clean your substrate very well, this can be another reason why fish poop can start building up in your tank.

Not Enough Or Inefficient Filtration

Like I said before, a small amount of oil film on the water surface of your tank is completely normal.

But if you don’t manually clean this oily film or have a filter or skimmer that does it for you automatically, it can start to build up over time…

Even running a sponge filter with an air pump can create enough surface movement for surface scum to disappear in a healthy aquarium.

The Oil From Your Hands

Sometimes, the oily film being formed on top of your aquarium water is caused by the oil from your hands.

This is something to keep in mind if you are putting your hands into your fish tank often. The natural oils from your skin and even the oils from skin products like lotions can cause a build-up of an oil film.

Just make sure you clean your hands properly and avoid putting your hands in the aquarium water if you think you may have chemicals or lotions on your skin.

You can also use gloves if you want to be extra cautious.

Airborne Grease And Other Contaminants Falling Into Your Tank

Last but not least…

One reason some people may not think about is the placement of their aquarium. Even though it sounds weird, the placement of your tank can cause it to have an oil slick on your aquarium surface.

This is common for people who have their fish tanks located in or near the kitchen of their home.

Airborne grease from cooking sprays, cooking oily food, and oil released/burnt off during cooking, in general, can fall on your aquarium surface and cause oil slick problems.

So make sure you keep the placement of your aquarium or planted tanks in mind…

How To Remove Bio Film On The Surface Of Your Fish Tanks

Now that you know what the main causes are for biofilm or that oily layer of film starting to form on your water’s surface, let’s talk about the three different ways to remove it.

Use A Surface Skimmer To Clean The Water Surface

I’ll be honest; the easiest way to never have to deal with surface scum is to use a filter with a built-in skimmer to take care of any film build-up on the surface of the water.

You also have the option to run a separate protein skimmer. Surface skimmers can clean your surface water whenever it starts to build up a layer of film.

You don’t have to run this 24 hours a day. You can run it once a week (or whenever you find it necessary to do so) for a few hours or until it clears all the surface scum from your tank.

Create More Surface Movement And Agitation In Your Fish Tanks

Another way to deal with surface scum or prevent the build-up of oily films is to have sufficient water surface movement and agitation.

A quick and easy way to do this is to run a sponge filter in your tank. (but you can also increase the flow of your filter, use power heads, etc.)

I had a 14-gallon cube tank with very little flow and movement. And a thick layer of biofilm would start to form after a few weeks…

I decided to put in a sponge filter because I wanted to have a second filter I could use to jumpstart new tanks or run my quarantine tanks.

However, the air bubbles from this sponge filter created enough surface water movement in my tank that the film on the surface of my fish tank stopped forming.

Manually Remove Surface Scum With A Paper Towel

Lastly, you can always remove surface scum the old fashion way with the use of paper towels.

This process can be time-consuming and ineffective, especially with larger tanks. But if you have a smaller tank, then using paper towels to remove surface scum can be your best bet.

The easiest way to do this is to lay the paper towel on the water surface of your tank and then quickly remove it to try and catch the oily film from the surface.

Throw out that piece, then repeat it until your entire tank is clean.

I know this process can be a bit wasteful and time-consuming. That’s why I just recommend having a skimmer that can do all the work for you.

Should I Be Concerned If An Oily Film Forms On Top Of The Water In My Aquarium

There is no cause for alarm if you have noticed that an oily film has started forming on your aquarium’s surface.

In general, biofilm or that oily film on the surface of your aquarium poses no immediate threat to your fish or other livestock within your fish tank. But if left to grow and build into a thick layer, then this film can start to deplete oxygen levels in your tank and suffocate your fish.

The surface of the water in your aquarium is responsible for gas exchange. If you let this film build-up, it can prevent the gas exchange from happening, and your tank can slowly become depleted of oxygen.

But if you regularly maintain your tank, have sufficient water movement, and don’t let this film get out of hand, you should have nothing to worry about.

What To Do If Biofilm Starts To Form On My Aquarium Driftwood

The surface of the water in your fish tank isn’t the only place where biofilm can start to grow.

Biofilm can start to grow on your hardscape, especially if you have driftwood or other types of wood within your fish tank.

You can read this post about biofilm on aquarium wood to learn more about how to get rid of it.

Getting rid of that kind of biofilm is a bit different than dealing with surface scum. Be sure to check out that article if you are dealing with it in your aquarium.

Final Thoughts On Getting Rid Of Water Surface Scum And Oily Films In Aquariums

This wraps up what I have to say about dealing with surface scum within your fish tanks.

If you are dealing with this issue, make sure you address the root cause of the problem…

But don’t worry, this film is harmless and usually just a bit of an eyesore. If you neglect it and allow it to build up, then that is a different story, and it can start to harm your livestock.

But the good news is…

Removing the film is easy to do, and I recommend using a filter with a built-in skimmer to handle it for you.

I hope this post was helpful and able to answer any questions you might have had about this topic.

I wish you the best on your fishkeeping journey and hope to see you in another post!

The post Oily Surface: How To Get Rid Of Film On Top Of Fish Tank first appeared on All Blue Aquatics.

In general, newly placed driftwood, spider wood, or any other type of aquarium wood will start growing biofilm on its surface within the first weeks of being introduced into your aquarium. This biofilm is harmless to your livestock and will usually disappear over time.

I remember setting up my very first aquascape. After a few weeks, I noticed a clear film start developing over my hardscape. Being a new fishkeeper, I started to panic and stress…

I quickly realized that biofilm is completely harmless. So, I was panicking over nothing.

The good news is that it’s completely harmless there to your fish, invertebrates, and snails. Also, there are many ways to get rid of it, which I’ll cover below…

You’ll also learn that biofilm is actually a great food source for some of your livestock. I’ll share with you the best livestock to use if you want them to eat and clean the biofilm out of your tank for you!

But there are some potential dangers you should be aware of when it comes to biofilm…

Below, I’ll talk about why this grows, what causes it, different ways to remove it, and what to avoid!

Why Is There Biofilm Growing On My Aquarium Wood

Using a driftwood hardscape looks great in an aquascape and can create many benefits for your ecosystem…

You can grow live aquatic plants on it; it is a great place for beneficial bacteria to grow. It gives your tank a nice look and feel, and if you have a shrimp tank, it can provide a good place for your shrimp to gather and hide.

But putting a wooden hardscape in your tank can also bring about the growth of biofilm. It’s quite common for driftwood, especially in a new setup, to start forming this clear layer all over it, known as biofilm.

While biofilm is pretty harmless, it can cause issues with your tank if left untreated…

Now, let’s talk about what caused this film to grow in the first place.

What Causes Biofilm Growth

Basically, biofilm grows from dissolved organic carbon found in the water column…

This can be a long story about a complex breakdown of the exact chemistry of why biofilm may grow in an aquarium.

But that’s boring, and I like to try to explain things in an easy-to-understand way. So here’s a quick rundown of why this happens and what may cause it to happen…

When organic materials break down in an aquarium, they release compounds that particular bacteria and other microorganisms love to eat.

And once driftwood is in your tank, it starts the natural processes of releasing carbohydrates and other nutrients, creating the perfect environment for surface biofilm to begin forming.

Also, this slime, mold, and fungi clear-looking substance can start to form because of other reasons as well.

Here are the most popular reasons why biofilm may start growing within your tank and water surface:

• Any wooden hardscape like Cholla Wood, Spider, Mopani, etc.
• Nutrients leeching from nutrient-rich substrate.
• Decaying plants
• Having an uneaten food source in your tank water can cause biofilm growth.
• Sometimes, even the overuse of liquid fertilizers can cause it to grow. (But more commonly, you’ll get an algae growth from this instead of a biofilm one.)

Now that you know what causes biofilm to grow in your tank. Let’s talk about how to remove biofilm from your aquariums.

How To Remove Biofilm On Wood And Other Places

There are 3 popular ways to remove biofilm within your fish tank…

You can manually remove biofilm, use chemicals, and use certain fish species or other livestock to clean up the biofilm in your tank.

But the best way to deal with biofilm in your tank is to understand what is creating it in the first place. If it’s from an excess food source, then you’ll want to make sure to cut back on feeding. If it’s from a hardscape, then it’ll usually disappear over time once nutrients stop leeching out from it.

Now, let’s talk about the 3 most popular methods for treating biofilm

Manually Removing Bioflim In Your Aquarium

One of the easiest ways to deal with biofilm within your tank is by manually removing it with a soft bristle brush or an old toothbrush. (just be careful that there are no residual chemicals on your old toothbrush before using it.)

This is best done during one of the days you plan on doing a water change. What I like to do is have the siphon close by, and as I scrap away the biofilm, I’ll use the siphon to suck it up like a vacuum.

Also, most aquarists would agree this is a great opportunity to clean any algae, uneaten fish food, dead plants, or any other build-up of organic matter around your aquarium.

You can check out this post on how to maintain a planted tank if you want more information on aquarium maintenance.

Just make sure you do not leave any biofilm floating around or get on any live plants after cleaning…

Even though it’s harmless to fish. It can cause plants to melt and die if biofilm starts to grow on or around it. (I learned this lesson the hard way when I left some biofilm on the carpet of my aquarium)

Using Chemicals To Remove Biofilm In Your Fish Tank

I honestly do not recommend this at all.

Biofilm is generally very easy to deal with and will stop growing over time.

However, some people recommend using a light mixture of bleach or hydrogen peroxide to take care of biofilm in your tank.

I think this is going a little overboard, and there are easier and more natural ways to get rid of biofilm, like manual removal or using livestock to eat it.

Using Livestock To Remove Biofim Within Your Fish Tank

This is probably the most natural and easiest method to remove biofilm.

There are plenty of fish and other creatures who love biofilm and will eat up. That means you literally don’t have to do anything and just leave the cleaning up to your clean-up crew within your aquarium.

If you don’t have a clean-up crew, I definitely recommend starting one since it’s a great way to clean your aquariums naturally.

So, let’s talk about the best livestock to choose in order to remove biofilm.

What Eats Biofilm In A Fish Tank

You’ll be surprised at what kinds of fish will eat biofilm. I’ve even seen some of my guppies chow down on the biofilm on my hardscape…

But the most popular choices of fish and other livestock when it comes to dealing with biofilm are:

• Otocincilus Catfish: These are my favorite cleaners, especially in smaller tanks with other nanofish.
• Bristlenose Plecos
• Shrimps: Biofilm is a great food source for shrimps, and many people who have shrimp tanks grow biofilm on purpose in order to feed their shrimp tanks.
• Snails: They’re another great choice when it comes to a clean-up crew.

Things To Keep In Mind If You Let Biofilm Go Untreated

And like I’ve mentioned earlier in this post. Biofilm is completely harmless to most fish species and is even grown purposely for feeding in shrimp tanks and other livestock that love to nibble on it.

But this film also uses oxygen to grow. So, if left untreated, you run the risk of having low oxygen within your aquariums.

Biofilm can also start to build up on the water surface, which only increases the issue of oxygen in your tanks. But a little more surface agitation from a sponge filter or HOB filter can take care of biofilm on the water surface of your aquariums.

These are just a few things to keep in mind. But it shouldn’t be a problem as long as you don’t let this film start running rampant everywhere.

Final Thoughts On What Eats Growing Biofilm In A Fish Tank

So now, if you see a clear slimey substance start to form along the surface of a piece of driftwood, you know exactly what it is and how to deal with it.

Just make sure not to stress too much about it. It’s a completely normal part of any growing ecosystem. Usually, it will go away over time.

You have the option of manually removing it, or you can hire some shrimp or Otocinclus catfish in order to take care of it naturally.

Just be sure you feed them algae wafers or let some algae or diatoms grow so they have a steady source of food after they’ve taken care of all the biofilm for you.

I hope I was able to answer any questions you may have about this subject, and I hope to catch you on the next blog post!

The post Biofilm On Aquarium Wood: What Eats Biofilm Growth first appeared on All Blue Aquatics.

You can safely treat tap water with water conditioners in order to remove harmful chemicals like chlorine and chloramine. Chlorine and chloramine can be harmful to your fish, invertebrates, snails, and even aquatic plants within your aquarium.

The safest and most convenient method to treat tap water for fish is with the use of water conditioners. There are also ways you can naturally treat tap water for your fish, which I’ll discuss in this post.

Also, I’ll go over how to treat your tap water with conditioners (my recommended method), why you need to treat your tap water, and other things you need to consider when it comes to the water quality within your fish tank…

How To Treat Tap Water For Fish In Your Aquarium

The easiest and surefire way to treat your tap water to make it safe for your fish is with the use of water conditioner products.

These products remove and/or neutralize the harmful chemicals that are contained within your tap water. This ensures it’s safe for your fish.

To treat your tap water, all you need to do is add the recommended amount of the water conditioner you are using. Give it a good mix, and your water will be good to go as far as removing the harmful chemicals within it.

(you still want to make sure your water temperature and other parameters are in line with the livestock you plan on keeping)

The two products I recommend you use are Seachem Prime and Seachem Stability.

You can check the price of Seachem Prime on Amazon Here

You can check the price of Seachem Stability on Amazon Here

You can safely dose 5X the recommended amount. So you can rest easy knowing that using the recommended amount will not cause harm to your fish and other livestock within your tank.

What I love about Seachem Prime is that it is more than just a de-chlorinator! It gives your fish a little added protection, which I’ll talk about below…

What Does Seachem Prime Do To Tap Water

This product safely removes/neutralizes the harmful chlorine and chloramine found in most people’s tap water.

But this product goes one step above and has the ability to detoxify ammonia, nitrite, and nitrates within your water…

Making your water safer for your fish and other livestock. People use this product with great success when cycling a tank and for emergency situations where your aquarium cycle may have crashed and you see a sudden spike in ammonia and nitrites.

That’s why I think it’s a great product to have and a must-have in any fishkeeper’s toolbox.

What Does Seachem Stability Do To Tap Water

Seachem stability has another purpose when it comes to treating your water. Stability jumpstart the beneficial bacteria colony within the water you are using.

Treating harmful chemicals like chlorine and chloramine is just one step to making your water safe for your fish. The next thing you need to do is have a colony of beneficial bacteria present within your filter media and substrate.

The fastest and easiest way to do this is to introduce the beneficial bacteria into your water. This post isn’t about cycling a tank, so I won’t dive deeper into this. But this is the reason I use Seachem stability.

And that’s why these two products work great hand in hand. They are perfect to use when first setting up your tank, and you can use them during your water changes when you need to do maintenance on your aquarium.

Why You Need To Treat Tap Water Before Adding It Into Your Aquarium

Just like us humans need a good environment to live and thrive in, your fish will need the same environment, too!

The reason you need to treat tap water is to remove all the harmful chemicals like chlorine and chloramine within it in order to make it safe for your aquarium and the livestock that will be living in it.

These harmful chemicals can burn your fish’s gills and be absorbed into their bodies which can result in damage to other parts of their bodies. This is the same danger that ammonia and nitrites can present.

That’s the reason why you should always treat any tap water before adding it to your aquarium. You’ll also want to ensure that the temperature and other parameters like pH and hardness are within the recommended range of the livestock you plan to keep!

How Do You Make Tap Water Safe For Fish Naturally Without A Conditioner

There are a few ways to make tap water safe for your fish naturally without the use of water conditioning products.

You can leave water sitting out for several hours with an air stone to let the chlorine evaporate within it naturally. But this doesn’t work with chloramine, so you will have to boil your water tap to remove any traces of chloramine within it.

These are the two most popular methods for making tap water safe. It can become time-consuming and very inconvenient. This is why I recommend treating your water with a water conditioning product instead.

But if you are going to do it naturally, here are a few things to keep in mind…

Aeration

This method will only work for chlorine in your tap water. You’ll want to ensure you use a shallow and wide container to get as much air contact as possible. It will help to leave the water sitting with an air stone to create some surface agitation and help with the process.

After 24 hours, you’ll want to use a test kit to test your water for any chlorine to see if it is safe. You’ll need to repeat this process for another 24 hours if your test comes back positive for chlorine.

Boiling

Chloramine will not evaporate like chlorine. So, if you have chloramine in your tap water and want to remove it naturally, then you’ll want to boil your water for a few minutes. Boil 10 gallons for 15-20 minutes.

Then, you’ll want to test and repeat this process as necessary until you test your water and it comes out negative for any chloramine.

Making Tap Water Safe For An Aquascape

Just like with a freshwater aquarium containing fish, you will need to treat your tap water in order to make it safe for an aquascape. You’ll also want to ensure that other water parameters are in the right range when setting everything up.

You can read this post: can I use tap water for an aquascape to learn more about this subject.

Remember, treating your water for chlorine and chloramine is just the first step when building a successful aquarium. You will want to ensure other water parameters and temperatures are in the correct ranges as well!

Final Thoughts On How To Treat Your Tap Water For Aquarium Fish

Now, you should understand the different ways you can make your tap water safe for your fish in your aquarium.

My recommended method is to use water conditioners like Seachem Prime and Stability. These products are great for detoxifying the harmful chemicals found in tap water and introducing the beneficial bacteria you need in your tank to house fish in your aquarium safely.

This saves you time and is a huge convenience compared to the natural methods I’ve discussed above.

But at the end of the day, it’s completely up to you to pick and choose which method you want to go with. At least you know what your options are.

I hope this post was able to answer your questions about treating tap water, and I wish you the best on your fishkeeping journey.

The post Making It Safe: How To Treat Tap Water For Fish first appeared on All Blue Aquatics.

The significant difference between a saltwater and a freshwater fish tank can be summed up into 4 different major categories. Those categories will be cost, equipment, type of livestock, and maintenance.

Below, I’ll dive deeper into each of these four categories so you understand the differences between these two types of fish tanks…

My goal is to have provided you with enough information by the end of this post so that you can wisely choose which type of fish tank is best for you and your current situation.

Difference Between Saltwater and Freshwater Aquariums

A freshwater tank and a saltwater tank have many differences that you should consider. The most obvious is that one can use fresh tap water and the other needs salt water. But there is more than just the difference in water type you should be thinking about…

Freshwater aquariums are great for first-time fish keepers. They tend to be lower cost and easier to maintain than their saltwater counterparts. Saltwater tanks tend to cost more and require more care to maintain one.

Also the types of livestock you can house within each type will significantly differ as well!

So, let’s dive deep into the differences between these two types of aquariums…

Cost

One of the biggest differences between these two types of tanks is the cost…

Hands down, a saltwater fish tank costs much more than a freshwater fish tank.

Saltwater aquariums require more special equipment. First of all, you will need to purchase salt in order to get the salinity of your water within the right parameters. Also, most people running a reef tank or saltwater setup opt to have a RODI Water System in order to get their water parameters within the precise ranges.

This means more cost in just water care alone…

But it doesn’t stop there. You will need more equipment to run a saltwater setup. Most of these tanks use a sump to filter and treat their water along with a protein skimmer. (some of these pieces of equipment may not be necessary depending on your setup)

Depending on what you’re housing in your tank, there may be certain requirements for water current, which means more equipment like a waver maker will be needed…

No, we’re not done yet…

The price of livestock drastically increases when dealing with saltwater fish tanks compared to freshwater tanks.

Last but not least, water tanks can be aquascaped with plants, but most of these plants will not thrive in a saltwater environment. Instead, saltwater tanks are aquascaped with coral…

And you bet coral is a lot more pricey than freshwater plants.

If you want to get an idea of how much a cheap freshwater aquascape will cost you. Then check out this post below:

How to aquascape on a budget.

So, if you are inexperienced in fishkeeping or have a limited budget, I suggest you go with a freshwater fish tank. But that doesn’t mean saltwater tanks are bad (I personally love them and plan on building one in the future)

I’m just saying when comparing the two. Freshwater tanks are more affordable than saltwater tanks.

Equipment

As you’ve probably guessed by now…

Another difference between freshwater tanks and saltwater tanks is the equipment. Freshwater tanks can be built and maintained with little to no pieces of equipment. (especially if you opt for the Walstad Method in your freshwater tank)

But you will need or want to have a few additional pieces of equipment when maintaining a saltwater tank—things like a sump, protein skimmer, sea salt, hydrometer, RODI System, etc.

Remember that the type of livestock and setup you want to run will determine what kind of equipment is going to be needed.

Which brings me to the next point. Let’s talk about the difference in livestock.

Livestock

Ok, I’ve already talked about the difference between livestock regarding price…

But now, let’s talk about the difference in variety!

I think Saltwater aquariums win in this category when we’re discussing variety.

The fish and different livestock you have to choose from within saltwater tanks is absolutely mind-blowing. These are some of the most exotic and colorful fish you will ever see!

This is also why I want to build a saltwater tank because of your options with this type of tank.

Don’t get me wrong, freshwater tanks still have a great selection of fish, but saltwater tanks just have more of an exotic and colorful selection of fish when compared between the two different aquariums.

Also, you can keep, grow, and maintain coral within a saltwater tank, which you don’t have in a freshwater setup.

Maintenance

Last but not least…

There is a difference in maintenance. Both tanks require care and maintenance. But saltwater systems will require more from you compared to a freshwater tank…

Saltwater livestock and coral are more sensitive to changes in water parameters. You’ll want to make sure you are an experienced aquarist and will be able to perform routine maintenance on a saltwater setup.

That means a more frequent and diligent maintenance routine will be required…

On the other hand, depending on what you stock in a freshwater tank, your maintenance routine can be pretty relaxed, especially if you have a low-stocked, well-balanced planted tank going.

You can check out this post on how do you maintain a planted tank for my recommended maintenance schedule.

And keep in mind this is just a general rule. Understand that maintenance depends on how you stock your tank and what you plan to keep in there.

Pros Of A Freshwater Aquarium

• More affordable.
• Easier to maintain.
• Able to use conditioned tap water.
• Use aquatic plants within your aquascape.

Pros Of A Saltwater Aquarium

• More colorful and wider variety of exotic fish and livestock.
• Able to use coral within your aquascape.

Final Thoughts On The Difference Between A Saltwater And Freshwater Fish Tank

These are the main differences between these two types of aquariums. By now, you should have a good idea of which aquarium is right for you.

If you are on a low budget and are new to fishkeeping or aquariums in general, Then I recommend you start with a freshwater tank. These tanks tend to be more budget-friendly and easier to maintain compared to a saltwater tank.

But if you want more of a challenge, you want a wider selection of exotic fish with vibrant colors, or you want to create an aquarium with coral, then saltwater will be the way to go.

At the end of the day, it’s completely up to you to decide. Everyone’s experience, budget, and what they want to create is different. It’s important to go with what you can afford and what will be the most fun for you to keep!
