The Reef Octopus Regal 300INT is a high-performance in-sump protein skimmer designed to deliver powerful filtration for saltwater aquariums up to 700 gallons. Its primary function is to remove dissolved organic compounds from the water column before they can break down into harmful nitrates and phosphates, resulting in a cleaner, clearer, and healthier aquatic environment. The skimmer's hybrid conical body is engineered to naturally stabilize and concentrate the organic-rich foam as it rises, ensuring efficient waste export and optimal performance for large, heavily stocked reef systems.

Constructed from high-quality cast acrylic, the Regal 300INT is built for durability and disassembles completely for easy maintenance. At its core is the advanced VarioS-6S controllable DC pinwheel pump, which offers superior efficiency and refined control over traditional AC pumps. This allows the user to electronically adjust both air and water flow rates through five variable speed settings, fine-tuning the skimmer's performance to match the specific needs of their aquarium. The included controller also features a float switch connection, providing an essential safety feature that can automatically shut off the pump when the collection cup is full.

This protein skimmer is ideal for the dedicated reef aquarist with a large system and ample sump space who demands precision, power, and reliability from their life support equipment. The ability to precisely control the skimmer's operation makes it perfect for hobbyists looking to maximize nutrient export and maintain pristine water quality. The combination of its robust build, innovative DC pump technology, and thoughtful safety features makes the Regal 300INT a premium choice for supporting a thriving reef ecosystem.
