Everything you need to know about water testing in saltwater aquariums

Regular water testing in saltwater aquariums is a crucial factor for long-term success in marine aquariums. Only by continuously monitoring water values can stable conditions be created in which marine fish, corals and invertebrates can thrive in the long term. The most important water tests for saltwater aquariums include measurements of salinity, pH value, carbonate hardness (KH), calcium, magnesium, nitrate, phosphate and ammonium.


These values provide information about water quality and help to identify imbalances at an early stage and correct them in a targeted manner. Precise testing is essential, especially in reef aquariums, in order to maintain the delicate biological balance.
