Endursal

Silbermann Endursal is a hardening salt to increase the total hardness and carbonate hardness at the same time. 
Very economical: only 15 g per 100 l increase the total hardness by 3° and the carbonate hardness by 2°.
Does not clump when stored dry.

We recommend: always measure the water values before use!
Overdosing or dissolving too quickly can cause turbidity.

The salt is highly hygroscopic and must be stored in a dry place!

Keep out of the reach of children!
