Colombo KH Plus

The correct Carbonate Hardness (KH) is mandatory for clear pond water and healthy fish and plants as well as a stable pH. KH is a measurement for the total amount of dissolved carbonates in the pond water. When the KH is too low the pH can fluctuate which is very harmful for the aquatic life.

If the KH is too low, the pH can fluctuate rapidly, which is very harmful to pond life.

An optimum KH value is between 6 and 10?DH. Test the KH value regularly with a Colombo test kit and add KH+ if necessary to keep the value at the desired level.
