Immediate help against nitrite
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 for the fish. sera Nitrite-minus provides quick help in case of acute pollution and immediately removes up to 1.5 mg/l nitrite 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.
Advice: The amount of nitrite in the aquarium water can be checked with the sera nitrite-test (NO2) or the sera Quick Test.
What is a new tank syndrome, when does it occur and what can I do against it? We will answer these and further questions in our contribution “What you should know about the new tank syndrome”.
The following chart provides an overview for evaluating the nitrite levels and when measures should be taken:
Add 5 ml of Nitrite-minus per each 20 l (5.3 US gal.) of water against 1.5 mg/l nitrite. 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.
