Colombo Kh+ 1000ml/7.000l

A good carbonate hardness (KH) is an essential condition for clear water, healthy plants and fish and a stable acidity level (pH).

The KH indicates the concentration of dissolved carbonates in your pond.

If this value is too low, the pH level can fluctuate rapidly, which is very harmful to the life of the pond.

Sufficient for :
1.000 ML = 7.000L + 4˚DH
2,500 ML = 17,500L +4˚DH
5.000 ML = 35.000L +4˚DH
15,000 ML= 105,000L +4˚DH
