The KH represents the buffering power of the water, which is the water’s capacity to oppose the pH variations, which are extremely harmful to the fish. The KH value should be over 3°dH and adapted to the biotope of the aquarium.
HOW should it be used?
Shake well before use. Add the dose of WATER KH & pH, preferably near the water outlet of the filter.
Dose: 10mL for every 40L (always for the total volume of the aquarium).
A single dose of WATER KH & pH leads to increases of 1°dH and 0.1 pH. Double the dose if you want an increase of 2°dH and 0.2 pH. Maximum increase per day of 2°dH.
