Grotech KH + CA 1 1000ml for rapid increase in carbonate hardness

The liquid for rapid increase in carbonate hardness.
Addition of 50 ml of KH + CA 1 increases the carbonate hardness by 2 ° KH at 100 l of water.
The ideal value is around 8-9 ° KH.

The KH value reflects the pH buffer capacity of the water. Too low a KH value offers the risk of a pH drop.
