SEA WATER

PRESAL is the new long-lasting auto-activating filter material. Highly effective three componentfilter material ensuring fresh, living aquarium water, low in detrimental substances (for seawater aquariums only).

PRESAL MARIN eliminates all detrimental substances such as albumin, ammonium, phosphate, phenol, organic acids as well as nitrate from seawater aquariums. PRESAL MARIN works selectively, i.e. essential components are not filtered out. An aquarium filtered with PRESAL MARIN will hardly age; it remains fresh and healthy for a long time. One package of PRESAL MARIN will last about 2 months and will keep an aquarium of up to 200 l free of polluting/toxic agents. When using the product for the first time, primary activation is recommended after 2-3 weeks. This way, subsequent intervals between reactivations will become longer. As the filter material is depleted, the nitrate content will slowly begin to rise. Then, it is time to reactivate. PRESAL MARIN should be used in a suction filter, f.e. Eheim.
