Water parameters nitrite (No2), nitrate (No3) and ammonia (NH3)

Estimated reading time: 2 minuten

This page is all about the waterparameters: Nitrite, Nitrate and Ammonia on this page. What is it? Why do you need to know? And what can you do if the values are incorrect?

Ammonia (NH3)

Ammonia is indicated by the NH3 value and is the first phase. Pollution of the water will increase the formation of ammonia in the aquarium. This contamination is, for example, excrement from shrimp (and other aquarium inhabitants), food that has not been eaten (get this out!), The rotting of a dead shrimp. If there is a dead shrimp in your tank, get it out as soon as possible. Ammonia is very dangerous for shrimp. In fact, it is poisonous to everything that lives in the aquarium. This value must be absolutely minimal, preferably zero. The optimal value is less than 0.2 mg / liter.

Lower NH3

  • Change the water;
  • Feed less;
  • Add plants to your tank.

Nitrite (No2)

Nitrite is created as an intermediate, the second phase, in the breakdown of harmful substances in the aquarium. Ammonia is converted by the bacteria in your filter into Ammonium (NH4) which is then converted into Nitrite. Nitrite is indicated with the No2 value. In too high a concentration Nitrite can cause septicemia.

Lower No2

  • Change the water.

Nitrate (No3)

Nitrate is indicated with the NO3 value and is the next phase (after Nitrite) in the breakdown of harmful substances. Nitrate is absorbed by the plants in your aquarium. If the Nitrate value is too high (above 50 mg per liter), a lot of algae will form and the shrimps and plants will weaken. The ideal value is a maximum of 20mg / liter.

Lower No3

  • Change the water;
  • Feed less;
  • Add plants to your tank.
