KH (Carbonate Hardness) Test Kit

KH (Carbonate Hardness) helps stabilise pH. Water with low KH is susceptible to rapid pH shifts, greatly stressing fish and increasing risk of disease. In marine applications a proper KH level is essential for healthy coral growth. Use this test kit to accurately measure KH.

This kit contains: liquid dropper bottle with child-resistant safety cap, easy-to-read instructions with information on how to test and correct unsafe water conditions, and glass test tube with snap-tight lid
