Salt water test kits

Natural water parameters are an essential prerequisite for a well nurtured aquarium. However, the intricate chemical differences between salt water and freshwater pose a challenge for the development of a precise water test. GIESEMANN professional test kits have specifically been developed for salt water and provide accurate measurements of all relevant water parameters – in laboratory-grade quality.
