API Nitrite Kit Fresh & Saltwater 180 Tests

API Nitrite Kit is a testing kit that is suitable for fresh and saltwater aquariums. It contains 180 tests and tests nitrite levels from 0 to 5ppm. It reads nitrite levels quickly and accurately, so your aquarium is safe for your fish. Nitrite is produced in the aquarium in the forms of fish waste, uneaten food, and by nitrifying bacteria in your aquariums natural cycle as it breaks down ammonia. Low levels of nitrite inhibit respiration and suppress the immune system, while high levels cause suffocation in fish. It contains 1 test solution, easy-to-read instructions, glass test tube and color chart.
