The unique CPR Aquatic SR2 Protein Skimmer design places the air inlet venturi prior to the pump impeller achieving an effect similar to needle-wheel skimmers in that the impeller chops the bubbles into the water giving smaller bubbles and improved contact time. The bio-filter section includes shaved plastic "Bio-Bale" which acts as both a biological filter and a bubble trap to prevent small bubbles from returning to the tank.
