The RK2000PE Protein Fractionator Skimmer by RK2 Systems is a high-performance filtration device engineered for demanding saltwater aquarium environments. It efficiently removes organic waste from aquarium water through a process called foam fractionation. By injecting air, and optionally ozone, into a counter-current flow of water, it creates a concentrated foam that collects and exports dissolved organic compounds before they can break down and degrade water quality. This robust fractionator features durable molded HDPE reaction chambers and a sophisticated counter-current design for optimal foam production. Key components include tuned Mazzei Venturi pumps with Kynar Venturi injectors, an ozone gas connection port, and precise airflow meters for fine-tuning. It boasts a convenient screw top lid, a clear sight gauge, and high-quality Hayward or Asahi ball valves. Internally, it utilizes top-tier MDM pumps and Spears piping and fittings, all proudly made in the U.S.A., ensuring exceptional reliability and longevity. An automated wash-down system is also included to maintain efficiency. The RK2000PE Protein Fractionator Skimmer is ideally suited for serious hobbyists, public aquariums, or commercial aquaculture operations running large or heavily stocked reef systems that demand superior water quality. Its industrial-grade construction, precise engineering, and advanced features like the automated wash-down system ensure consistent, high-level performance with minimal maintenance. This skimmer is designed for those who require the most effective and reliable solution for preventing nutrient build-up and maintaining pristine conditions in their aquatic environments.
