Reef Octopus Regal 250-EXT Recirculating Protein Skimmer
The Reef Octopus Regal 250-EXT is a professional-grade external recirculating protein skimmer designed for large reef systems up to 600 gallons. Featuring a substantial 10-inch wine-glass body, this skimmer utilizes a recirculating design where the VarioS-6S DC pump focuses entirely on mixing air and water within the reaction chamber. By using a separate feed pump (sold separately) to move water through the skimmer, users can perfectly tune the dwell time, ensuring that even the most stubborn organic compounds are efficiently removed.
