Aquaforest TestPro Alkalinity is designed to rapidly measure carbonate hardness (dKH) and alkalinity (meq / L) in salt water. Alkalinity levels should be analyzed regularly, along with other critical water parameters such as Calcium and Magnesium. The recommended values of carbonate hardness are in the range of 6.5 to 8.0 dKH. The test contains enough reagent to make about 78-100 measurements in that range.
Within the test is the reference solution - Kh 7.3 +/- 1%
