Salifert Fresh KH Test – Carbonate Hardness (KH) Test for Freshwater Aquariums

Salifert Fresh KH Test Salifert Fresh KH Test is a drop test for measuring carbonate hardness (KH) in freshwater aquariums. KH (alkalinity) is closely linked to pH stability , making it an important parameter during water changes, aquarium set-ups and routine maintenance. The result is read by counting drops and checking a clear colour change. What the test measures – Carbonate hardness KH in dKH Key features – Fast drop test for routine freshwater water testing – Clear end point colour change from blue to yellow – Drop count method for quick checks during water changes and parameter adjustment – Useful for monitoring pH stability in freshwater aquariums
