The first step in creating a successful freshwater fish tank is to ensure your water is safe for the fish and other livestock you plan on keeping within your aquarium.
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 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.

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.
