Phos Fx consists of porous polymer resin beads infused with iron oxide. The iron oxide binds with phosphate and silicate as water passes over the beads. Phosphate and silicate control is important in freshwater, marine and reef aquariums for algae control. Limiting phosphate and silicate helps to starve algae and reduce maintenance. Phosphate also binds with calcium and can inhibit calcification in corals. The porous beads eliminate the break-down and dust problems often found with GFO. The spherical beads are especially effective when used in a contact chamber. The uniform beads help to ensure maximum contact time and nutrient removal. Phos Fx can be regenerated several times with Regen Fx.Phos Fx is recommended for freshwater, marine and reef tanks to reduce algae growth and control phosphate levels. Drop a bag or two into your filter and see the difference it makes! Available in 250ml & 500ml.
