water care products by EHEIM are based on natural microbiological substances.
It is not the chemical substances, but above all carefully combined organisms that determine the effect.
This means careful improvement of the water quality without disturbing the ecological balance.
In principle, water care products should always be used sparingly. Not as a replacement for filter technology, but to support it.
When water values have to be corrected selectively. When speed is of the essence. Or if the filter cannot manage it alone.
