The RK25PE Protein Fractionator Skimmer is an advanced filtration device engineered to efficiently remove organic waste from saltwater aquarium systems. Utilizing a sophisticated counter-current design, it injects air, and optionally ozone, into a reaction chamber where it mixes thoroughly with incoming water. This process creates a dense, concentrated foam that effectively captures dissolved organic compounds, isolating them from the aquarium water and exporting them as waste.

This robust fractionator features durable molded HDPE reaction chambers and a crucial wash-down system to maintain clean surfaces and prevent foam inhibition. Key components include tuned Mazzei Venturi pumps and Kynar Mazzei Venturi injectors for precise air and ozone delivery, along with an ozone gas connection port and air flow meters for optimal control. It boasts a screw top lid, clear sight gauge, and high-quality Hayward or Asahi ball valves, all supported by MDM pumps and Spears piping and fittings, ensuring reliable operation and longevity.

Designed for serious reef aquarists and professional setups, the RK25PE Protein Fractionator Skimmer is ideal for those requiring superior water clarity and pollutant removal in large or heavily stocked marine environments. Its industrial-grade construction, automated features like the optional venturi cleaning, and efficient foam fractionation process make it a top-tier choice for maintaining pristine water quality with minimal manual intervention.
