Salifert KH Test Kit

The Salifert KH Test Kit measures carbonate hardness (alkalinity) using a precise drop-count titration method, covering a range of 0.5 to 20 dKH. Maintaining stable KH is essential for both reef aquariums (where it supports coral calcification) and planted freshwater tanks (where it prevents dangerous pH swings). Each drop of titrant represents a measurable KH increment, allowing for straightforward and accurate readings. The kit typically yields around 100–150 tests per bottle. Salifert's reagent is formulated for minimal color ambiguity at the endpoint, reducing the risk of misreading results compared to kits with gradual color transitions.
