JBL ProAquaTest NH4 Ammonium, Refill

The JBL ProAqua Test NH4 is a water test for analysis of ammonium and ammonia content in freshwater and seawater aquariums, as well as in ponds.

The degradation of all organic substances (feed and plant residues, excretions of fish) in the aquarium and pond is done via the so-called nitrogen cycle. Proteins are converted into ammonium and this into nitrite and harmless nitrate. Certain bacteria are responsible for this process. By measuring the individual intermediates ammonium, nitrite and nitrate, statements can be made about the "functioning" of the system. For example, medicines for curing fish diseases can damage the beneficial cleansing bacteria and thereby lead to an increase in ammonium and / or nitrite levels. As a rule, ammonium will not be measurable in a well-maintained aquarium with a powerful biological filter. Ammonium is a plant nutrient and non-toxic to fish in low concentrations. Depending on the pH value, however, ammonia (BH3) can form from the ammonium. For this reason, should always be carried out with the ammonium measurement, a pH measurement.

Recommended ammonium values:
Freshwater aquarium (community aquarium): <0.25 mg / l
Malawi Lake Tanganyika Aquarium: <0.25 mg / l
Plant aquariums with few fish (aquascaping): <0.25 mg / l
Marine aquariums: 0-0.25 mg / l
Ponds: <0.1 mg / l

Inexplicable fish diseases or fish deaths are often the cause of a bacterial change - a water test gives quick and safe information about it!
