NT Labs Ammonia Test Kit

What is ammonia?
Ammonia is the main waste product produced by fish as a result of feeding. It can also be generated by the decay of uneaten food or decaying organic matter, such as plant leaves. It is invisible to the naked eye and its presence or absence cannot be determined by looking at the water alone. It is extremely toxic to the fish but is broken down into less toxic nitrite by the beneficial bacteria found in the filter.

What is the correct ammonia level?
There is no occasion where any ammonia is tolerable. A level of zero mg/l (ppm) should be maintained at all times.

What do I do if the ammonia level is wrong?
If a level of 0.2 mg/l (ppm) is found, add a filter booster such as Filter Starter. If a level above this is found, then a substantial water change is essential. Change 25% of the volume for 0.5 – 1.0 mg/l (ppm) ammonia and 50% for ammonia levels above this. Add Ammonia Remover to the filter compartment to remove ammonia. If any amount of ammonia is found, then it is important to check other vital water quality parameters, in particular pH, KH and nitrite.
