pH - GH - KH

Stability and safety. Buffers and stabilizes the pH value. Is effective against biogenic decalcification. Creates appropriate conditions (e.g. for African cichlids)

Dennerle KH + elixier in the freshwater aquarium ensures optimal carbonate hardness and stable pH.

In time, a marine aquarium will lose its carbonate hardness (KH), which may lead to a dangerous acidity level (pH value).

Tetra pH/KH Plus allows a precise and controlled increase of carbonate hardness (KH). The pH value depends on KH and carbon dioxide (CO2) content. If the CO2 level is constant, the pH value can only be influenced by the KH value.
