Carbonate Hardness Test Kit

Carbonate Hardness (KH) helps stabilize pH in the aquarium/pond. Water with low KH is susceptible to rapid pH shifts, greatly stressing fish and increasing the risk of disease. Use this kit to easily and accurately measure KH.

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