ReefPure PHOSaR is a new high performance Iron based media Phosphate and Arsenic remover with a special shape and composition especially for water filtration. ReefPure PHOSar contains Iron Oxide in a new pelleted form which offers higher hydrodynamic performance compared to the competitor's Iron-based granular product. Microanalysis reveals that the pelleted media found in ReefPure PHOSaR has a more uniform and efficient pore structure to allow greater Phosphate absorption to levels below 4ppB.
