(CARBONATE HARDNESS)

Tests tap water and fresh or saltwater aquariums for carbonate hardness(KH), the measure of dissolved carbonate and bicarbonate ion concentrations, also called alkalinity.

* For fresh & salt water
* Helps detect stress on fish caused by rapid pH shifts, the result of low levels of KH
* Helps to maintain the correct buffering capacity in aquariums.
