Ammonium NH4 is a chemical compound which is normally converted into nitrites and then into nitrates in the nitrogen cycle.
The pH is one of the values which are vital to the good health of an aquarium or a pond. This test quickly measures the acidity of the water.
Nitrates test for freshwater and seawater
Nitrites test for freshwater and seawater
Phosphate test for freshwater and seawater
Bicarbonates (KH= bicarbonates / carbonates) have a stabilising effect on pH variations in the water. This is therefore one of the most important tests in reef aquariums.
The general hardness (GH) indicates the quantities of magnesium and calcium salts dissolved in the water. The recommended level is between 6 and 20°GH in freshwater, depending on the species kept.
