PhosFX is a new phosphate removing media from BlueLife USA, makers of the widely used ClearFX aquarium water polishing filter. PhosFX is different from granular ferric oxide (GFO) and is said to absorb PO4 twice as fast, with a higher adsorption capacity.
BlueLife USA’s PhosFX can be regenerated up to 6 times over its lifetime making it competitively priced compared to some of the higher priced GFO media. BlueLife also offers their Phos Fx Regenerate solution for recharging the phosphate removing filter. BlueLife USA is making PhosFX available in 250ml and 500ml sizes with the latter being suitable for 250 gallons of aquarium water. [BlueLife USA]
