Ammonia is produced when uneaten food and waste decompose. This is highly stressful and toxic to fish if left to accumulate within the aquarium. To know if you have a build up of ammonia, test weekly.


Ammonia is produced by fish as they breathe and pass waste into aquarium water. Other sources include decomposing waste from uneaten food and other organic contributors. This is highly stressful and toxic to fish, in particular in new aquariums and if left to accumulate within the aquarium fish loss will occur. To know if you have a build up of ammonia, test weekly to ensure ammonia is detected or more frequently during new aquarium establishment, post medicating, etc.

Why did my aquarium pH level rise rapidly after changing my gravel?

Some buffering by natural gravel is expected, but it will have a more dramatic effect on tap water with little buffering capacity (KH). At least 30-40mg/L KH temporary hardness is required to stabilize pH levels.

Is the Fluval Ammonia Test kit affected by ammonia binding/locking supplements?

The Fluval Ammonia test kit uses the Indophenol method, which is typically not affected by ammonia binding/locking products. Given that there are many such water supplements on the market today, we cannot guarantee this will always be the case.

Why did my test kit reading show a different pH value than when I brought a water sample to the store?

It’s best to bring both your water sample and test kit to the store, in order to measure both at the same time. Conditions can differ between locations sufficiently to affect test kit results. Furthermore, if your container had too much air in it, the pH level is likely to have changed.
