When it comes to owning the aquarium, there are many things that go into the maintenance section. One thing you should never forget is aquarium water maintenance.

As part of water maintenance, you should use an aquarium water conditioner. This is because sometimes people even add tap water to the aquarium before treating it.

That process involves changing some of the water, but tap water contains chemicals, minerals, and heavy metals that keep the water safe for us to drink, but make it deadly for fishing. Fortunately, you can solve that problem by using a tap water conditioner.

But how long does it take for the water conditioner to work? And what is the best aquarium water conditioner? In this guide, we’ll tell you everything you need to know about tap water conditioning products, including detailed water conditioner reviews and our personal recommendations.

So what is the best aquarium water conditioner? We can answer that question below with a list of quality water conditioners for your aquarium.

9. Tetra AquaSafe PLUS

Best Aquarium Water Conditioner

This is another cheaper alternative to Prime in terms of volume, especially for a 1-liter (33.8-ounce) container.

Why Use Water Conditioner in Aquarium?

Water conditioners are helpful when it comes to treating tap water to make it safe for fish.

Conditioners remove chlorine commonly found in tap water. Chlorine as a chemical is good at keeping bacteria and other microorganisms away so you can use the water for human consumption.

The same level of chemical chlorine that is safe for humans can easily be toxic and kill the fish in the aquarium. You must use the water conditioner to remove any chlorine and chloramine in the water.

It’s not just about removing chemical chlorine, water conditioner is also good at removing heavy metals from water. Such heavy metals are often found in tap water.

It should also be great when it comes to removing ammonia, nitrites and nitrates from water. As you can see, you always end up with clean water.

Depending on the water conditioner, it can also help to create an important layer of sludge to protect the fish. In general, you should have a safe environment for aquatic life.


What is the Best Aquarium Water Conditioner?

When it comes to choosing the best aquarium water conditioner, it’s all about a model that can always deliver performance. You don’t want to pick one with too many additives that won’t even perform.

For the list above, you can always settle for Seachem Safe as it is one of the best of the many available in the industry. The model offers exemplary performance to easily clean the water. The impressive concentrated solution also reduces nitrites and nitrates that you can find in aquarium water.


How Does the Aquarium Water Conditioner Work?

The water conditioner is important when it comes to cleaning the water and making it safe for fish. So how does the water conditioner really work? It’s pretty easy once you understand the chemistry behind it.

The conditioner starts by neutralizing the chlorine in the water. This is done by the formation of ionic bonds and will thus turn the chlorine in the water into harmless components. Once this happens, the water must be safe for aquatic life.

The same chemical process will take place when it comes to removing other components such as chloramine and heavy metals.


Which Water Conditioner is Best?

After reading this article, guess which one I decided I preferred.

Yes, Seachem Prime.

And no, Seachem doesn’t pay me a lot of money to promote their products.

Although, if they wanted to give me a big check, I wouldn’t worry about it either.

I promised myself that I would keep an open mind while writing this article. I knew I preferred Prime, but everyone should always be open to new information, including myself.

But I have to admit that after looking at the numbers for all these different products, I came to the conclusion that Prime is the best water conditioner.

I don’t really believe the aquatic experts’ claim that Prime’s odor bothers aquarium fish. I’ve added Prime to my tanks literally hundreds of times now.

The fish don’t try to escape the new water or swim away if I fill the tank right away.

So it all boils down to this: I want a water conditioner that removes chlorine/chloramines, detoxifies nitrites and nitrates, and is reasonably priced. Prime is the clear winner.



There is no doubt that you now know that this could be the reason why your fish has been dying all the time. You can’t just add tap water to the aquarium and hope the fish will survive.

Now that you know more about Best Aquarium Water Conditioner, you should be able to have one of the best products for your aquarium today. Each of the models discussed above will give you the performance you deserve when it comes to treating your water. You can choose according to your preferences.
