Octo Regal 300INT Protein Skimmer

Reef Octopus Regal 300-INT Protein Skimmer

The Reef Octopus Regal 300-INT is the titan of the Regal series, designed specifically for massive residential systems and large-scale commercial reef displays. Boasting a substantial 12-inch wine-glass body, this skimmer is engineered to process the heavy biological waste produced by systems up to 740 gallons. Powered by the VarioS-6S DC controllable pump, it offers the rare combination of high-volume processing and surgical precision, allowing the user to electronically adjust air and water flow to match the specific needs of their ecosystem.

Built with industrial-grade cast acrylic, the Regal 300-INT is designed for longevity and peak efficiency. The VarioS controller provides a "soft start" to prevent overflow upon startup and includes a waterproof connection for the integrated float switch—a critical safety feature for large-scale systems to prevent salt creep and waste re-entry. With its heavy-duty geared gate valve and turbulence-reducing bubble plate, the Regal 300-INT provides the most stable foam production available for high-capacity in-sump filtration.
