Why test for Nitrite & Nitrate?

Overfeeding, too many fish or inadequate biological filtration can lead to an unhealthy nitrate level. Nitrite in the aquarium interferes with fish respiration, and high levels of nitrite quickly lead to fish death. A high nitrate level causes poor water quality and increases the suseptibility of fish to disease.

When to test Nitrite & Nitrate?

Regular testing of nitrite and nitrate are an essential part of routine aquarium maintenance. Nitrite and Nitrate should be tested weekly to make sure they do not reach undesirable levels.
