Tetra Tetratest KH Carbonate Hardness #16611

Why Test? In most waters, bicarbonate salts form part of the water hardness. These bicarbonate salts make up the carbonate hardness (KH) value. Bicarbonates have an important function in the overall chemistry of aquarium water. They act as a pH buffer, preventing sudden and potentially harmful changes in the acidity or basicity of the water. The Tetratest KH kit was professionally developed to accurately determine the carbonate hardness of your aquarium water. Kit contains one 10-ml test reagent, a test vial and instructions. For freshwater, marine aquariums and ponds. Shipping weight: 1/4 lb.
