Immediate help against nitrite

  • removes up to 1.5 mg/l of nitrite per dosage
  • prevents new tank syndrome

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.

 

  • removes up to 1.5 mg/l of nitrite per dosage within shortest time
  • prevents new tank syndrome and provides immediate help in case of acute pollution
  • binds nitrite and converts it into organic amines that are utilized by the filter bacteria

 

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”.


New tank syndrome course with and without Nitrite-minus


The following chart provides an overview for evaluating the nitrite levels and when measures should be taken:

NO2 Evaluation Measures
0.0 mg/l good -
>0 – 0.5 mg/l action required dose sera bio nitrivec
0.5 mg/l critical possibly dose sera Nitrite-minus (1-fold dosage)
1.0 mg/l harmful dose sera Nitrite-minus (1- fold dosage)
2.0 mg/l dangerous dose sera Nitrite-minus (possibly 2- fold dosage)
5.0 mg/l toxic dose sera Nitrite-minus (possibly 4- fold dosage)
