Salifert Profi-Test Kits - KH + Alkalinity (Carbonate Hardness) is an ideal addition to any aquarist's store cupboard.

The Carbonate Hardness or KH level of the water in a reef aquarium is a vital component for healthy and strong coral growth. The KH level denotes how alkali or acidic the water is, which can affect fish and coral health if it isn't at the right level.

The ideal range for a reef aquarium is between 8.1 and 8.4, so regular testing means that you can monitor this sensitive level. Salifert's precise tests are sensitive enough to detect even the smallest change.

With enough solution to perform between 100-200 tests, this kit is not only reliable but long lasting too.
