Preis Aktivant P 900 gr

Highly active 3-component filter material for fresh, lively, waste-free aquarium water (exclusively for fresh water).

PRESAL removes all harmful substances from the water in your freshwater aquarium: albumin, ammonium, phosphates, phenols, organic acids, as well as all nitrates. PRESAL acts selectively, c. to d. that all the essential substances are kept. All aggressive elements contained in the pipe water are quickly eliminated. Water treated with PRESAL barely changes and stays fresh and healthy for a long time. One pack of PRESAL is enough to rid an aquarium with a capacity of up to 200 l of any pathogen for 2 months. If the aquarium is larger, increase the amount of PRESAL. When using for the first time, it is recommended to activate PRESAL 2-3 weeks later, depending on the level of nitrates. The intervals between the following activations increase. When the filter material is used up, the nitrates increase and the pH rises slowly. PRESAL must then be reactivated. The use of PRESAL is possible in all models of suction filters.
