Iron based granulate for removal of phosphate in sea and fresh water tanks.
Slow water flow in a filter bypass. 1 kg can absorb approx. 60 gr. of phosphate. Biophos 2 should be exchanged as soon as PO4 is measurable at the PO4 reactor outlet. To enforce the effect of the adsorber we recommend to place the wet adsorber overnight in the freezer. Recommended in any tank system.
Rinse the adsorber with hot tap water before use.
