The Reef Octopus Regal 250-INT is a high-performance, in-sump protein skimmer designed to efficiently remove dissolved organic waste from large saltwater aquarium systems. By creating a massive volume of fine air bubbles, it effectively strips proteins and other pollutants from the water column before they can break down into harmful nitrates and phosphates. This process is crucial for maintaining exceptional water clarity, promoting stable water parameters, and supporting the health of sensitive corals and marine life in a thriving reef environment.

This skimmer features a sophisticated hybrid cone body for stable foam production and is powered by the highly controllable Reef Octopus VarioS 5500s DC pinwheel pump. This variable speed pump allows for precise adjustments, consuming only 35-50 watts while producing a formidable air draw of 1200-2000 lph. The unit has a compact 16.5 by 11-inch footprint and stands 24 inches tall, designed to operate optimally in a sump with a water depth of 7 to 8.5 inches. Its quality construction ensures durability and quiet, reliable operation for your filtration system.

The Regal 250-INT is an ideal filtration solution for the serious aquarist managing a significant bioload. It is rated for heavily stocked reef tanks up to 300 gallons, medium-stocked systems up to 500 gallons, or lightly stocked aquariums as large as 600 gallons. Hobbyists who demand precise control, energy efficiency, and powerful waste removal to maintain pristine conditions for demanding SPS corals and delicate fish will find this skimmer to be an essential and dependable component of their life support system.
