PondCare Nitrite Test Kit

Quickly & accurately measures the level of nitrite in pond water, reading levels from 0 ppm to 5 ppm. Makes 180 tests. Determines the level of nitrite, a toxic chemical produced when nitrifying bacteria break down ammonia in pond water.

High nitrite levels may cause pond fish to suffocate & die. Includes test solution, glass test tube with cap, color chart & easy-to-follow instructions.

How often should I test for nitrite?
Regular testing is necessary to make sure the ammonia level is safe. Pond water should be tested for nitrite every other day when the pond is first set up, and once a week after the biological filter has been established (in about 4 to 6 weeks).

Ammonia levels will first rise then nitrite will begin to rise as the biological develops. The nitrite level should always be zero once the biological filter is established.
