LaMotte Test Kits for Nitrite

This is an intermediate compound formed in the oxidation (nitrification) process of ammonia becoming nitrate. Nitrite can become toxic in recirculating systems. Nitrites interfere with the ability of the fish’s blood to take up oxygen (levels as low as 0.2 mg/l can cause “Brown Blood” problems with catfish). Testing takes 5 minutes. There are 50 tests per kit. Range: 0.05 to 0.8 mg/liter.
