The RK150PE Protein Fractionator Skimmer by RK2 Systems is a high-performance filtration device designed for advanced saltwater reef aquariums. It utilizes a sophisticated protein fractionation process, injecting air and optionally ozone into a counter-current water flow to create a dense foam. This foam effectively captures and removes dissolved organic waste, proteins, and other pollutants from the aquarium water, significantly improving water clarity and overall system health.

Key features of this robust skimmer include molded HDPE reaction chambers, a precise counter-current design, and an integrated wash-down system to maintain optimal performance. It is equipped with tuned Mazzei Venturi pumps and Kynar Mazzei Venturi injectors for efficient gas mixing, alongside an ozone gas connection port and air flow meters for precise control. Other notable components include a secure screw-top lid, a clear sight gauge, high-quality Hayward or Asahi ball valves, and reliable MDM pumps and Spears piping, all proudly made in the U.S.A. An optional automated venturi cleaning system further enhances its low-maintenance operation.

This RK2 Systems Fractionator is an ideal choice for serious reef aquarists with medium to large-sized systems who demand exceptional water quality and reliability. Its robust construction and advanced features, such as the automated rinse systems and high-quality components, ensure consistent and efficient waste removal with minimal user intervention. It is particularly well-suited for setups where maintaining pristine water parameters is critical for sensitive corals and demanding livestock, offering a premium solution for nutrient export.
