The Carbonate Hardness (kH) value of water is the basis for the stability of pH, both in freshwater and marine. Low kH has a negative effect on the growth of plants and may cause an unmanageable pH fall.

The lower the Carbonate Hardness value of water, the less buffering effect it has on pH values and so pH becomes unstable.

To hold pH at prescribed levels we recommend: Freshwater kH =70 to 170ppm, cichlids kH = 125-250ppm, marine kH = 125-250ppm.

Dose: 1 tab per 60 Litres raises the kH level by 20ppm.
