Prevents the precipitation of lime and other mineral salts
Prevents limescale deposits in the pool and filter system
Dosage depends on water hardness
Liquid, foam-free, easily soluble, non-irritant

Hard water also increases the pH value due to the lime content. Water temperatures that are too high can also trigger lime precipitation. The BWT hardness stabiliser has a stabilising effect on fluctuating pH values. It reduces limescale deposits and thus prevents the pool water from becoming cloudy.

We recommend adding the easily soluble hardness stabiliser to the water in spring or at the beginning of the pool season.

The amount required depends on the water hardness:

up to 20°dH = 200 ml/10 m³
from 20°dH = 300 ml/10 m³
