The Regal 200INT Protein Skimmer is an innovative in-sump filtration device designed to efficiently remove organic waste from saltwater aquariums. This high-performance skimmer is suitable for systems up to 400 gallons, providing powerful and reliable water purification by creating a rich foam that extracts dissolved organics before they can degrade water quality. Its robust design features a hybrid conical body that naturally stabilizes and concentrates the foam, ensuring optimal collection of pollutants. This advanced skimmer is equipped with a new generation Reef Octopus controllable Direct Current VarioS-4S pinwheel skimmer pump. Unlike traditional AC pumps, the VarioS-4S DC pump allows for precise electronic control over the motor's rotational speed, enabling users to adjust air and water flow rates into the skimmer across five different speeds with the push of a button. The VarioS Controller further enhances functionality by including a float switch connection, providing an added security feature to automatically shut off the skimmer pump if the waste collector becomes full. The Regal 200INT Protein Skimmer is ideal for dedicated reef aquarists with sumps that accommodate its size and who manage aquariums up to 400 gallons. It is particularly well-suited for hobbyists seeking refined control over their filtration performance, energy efficiency, and reliable operation. Those who prioritize high-quality construction, ease of maintenance through complete disassembly, and integrated safety features like automatic shut-off will find this skimmer an excellent investment for maintaining pristine water parameters.
