The RK2 Systems RRK1000PE Protein Fractionator Skimmer is a high-performance, industrial-grade filtration device engineered to meticulously remove dissolved organic waste from saltwater aquarium systems. Utilizing a sophisticated counter-current design, it efficiently injects air, and optionally ozone, into the water column, creating a dense foam that selectively binds and exports harmful organic compounds before they can degrade water quality, ensuring a pristine aquatic environment. This advanced skimmer features robust molded HDPE reaction chambers, a precise counter-current design for optimal foam formation, and a critical wash down system to prevent foam inhibition. It is equipped with tuned Mazzei® Venturi Pumps and Kynar® Mazzei® Venturi Injectors, an ozone gas connection port, and accurate air flow meters. Additional high-quality components include a secure screw top lid, a clear sight gauge, Hayward® or Asahi® ball valves, and durable MDM® pumps and Spears® piping and fittings, all proudly made in the U.S.A. An automated venturi cleaning system is available as an optional enhancement. This advanced protein skimmer is ideally suited for large-scale reef aquariums, public aquaria, or demanding commercial aquaculture operations where uncompromising water quality is paramount. Its robust construction with molded HDPE reaction chambers, high-quality MDM pumps, and Spears piping ensures exceptional durability and reliable long-term operation, making it a cornerstone for maintaining superior biological health and clarity in the most challenging marine environments.
