Due to bacterial, animal and vegetable metabolism, there is a progressive decrease in carbonate hardness in the aquarium. The concentration should never fall below the 3° dKH level in freshwater aquariums. ABA KH POWDER allows to increase the carbonate hardness in the aquarium also avoiding the fall of the pH. 

DOSES: 5 ml/50 liters to increase by 5 degrees. 

Avoid dissolving the salt directly in the aquarium.
