The PO4X4 Phosphate Remover is a uniquely-engineered polymer-based mini pellets which works without the risk of Iron-ions leakage.

The pellets do not clump together and can be readily used in fluidized filters.

Has very high surface area and can absorb approximately 4 times more phosphate than most other phosphate removing products. Effective algae prevention.

250 ml will remove 3 ppm of phosphate and silicate from roughly 8 liter of fresh water or 4 liter of marine water.
