Sera Test Ammonia NH3 / Ammonium NH4

Test for Ammonia NH3 / Ammonium NH4

High ammonium levels indicate a disturbed or not fully developed bacterial activity in the filter.

Ammonia (NH3) formed from ammonium (NH4) in case of pH values above 7 is especially dangerous.

Even ammonia values of 0.02 mg/l lead to gill damages in the long term.
Therefore you should always check the pH value in addition to the NH4 level.

Directions for use:

Shake reagent bottle well before using!
Do not allow tested water to contact aquarium or pond water!

1. Rinse the measurement vial several times with the water to be tested, then fill to the 10 ml mark (freshwater) or the 5 ml mark (marine water). Dry the vial on the outside.
