Aqua One Carbonate Hardness (KH) Test Kit

The correct Carbonate Hardness level will help maintain a balanced and stable pH. With the aid of this test kit you will help ensure your aquatic pets live long, happy, healthy lives. 

Carbonate Hardness (KH) is a "buffing" element in aquarium water which stabilises the pH. A low KH can result in the pH value continuously dropping (going acidic) regardless of how often bicarbonate soda (pH up) is added. The break down of toxins within the aquarium filtration system results in the formation of an acid, which depletes the Carbonate Hardness reserve causing the pH to become unstable. The correct Carbonate Hardness level will not only stabilize the pH but also act as a supply of carbon dioxide for aquatic plants. It is also an important element to consider when trying to simulate the correct breeding conditions for particular species.
