Accumulating nitrite (“new tank syndrome”) is a threat during the starting phase of a new aquarium, after a disease treatment or a filter change, since insufficient filter bacteria are present for breaking down toxic nitrite to the plant nutrient nitrate. A nitrite level of 1.0 mg/l can already be harmful to the fish. sera Nitrite-minus provides quick help in case of acute pollution and immediately removes up to 1.5 mg/l nitrites per dosage. It converts toxic nitrite into organic amines that are then utilized by bacteria. sera Nitrite-minus is very well tolerated by ornamental fish, invertebrates, and plants, and can be dosed up to 5-fold.
Add 5 ml of Nitrite-minus per each 5.3 US gal. (20 l) of water against 1.5 mg/l nitrites. Dose up to 5-fold in case of acute pollution or every other day between the 5th and 15th day during the biological activation. Always check water parameters and ensure good aeration of the water.
