Octo SRO 5000EXT Recirculating External Protein Skimmer

Reef Octopus SRO 5000EXT Recirculating External Protein Skimmer

The Reef Octopus SRO 5000EXT (Super Reef Octopus) is a heavy-duty external recirculating protein skimmer designed for large marine systems up to 500 gallons. Unlike standard internal skimmers, the 5000EXT utilizes a recirculating design where the Bubble Blaster HY-5000S pump focuses entirely on mixing air and water within the skimmer body. A separate feed pump (sold separately) is used to move water from the sump into the skimmer, allowing the aquarist to perfectly tune the dwell time for maximum nutrient export.

The SRO series is famous for the Bubble Blaster pump, which is widely considered one of the most reliable and efficient pinwheel pumps in the industry. These pumps feature a silicon carbide shaft and bearings for extreme wear resistance and a digital control circuit that monitors the motor's status. The skimmer body is constructed from high-grade cast acrylic and features a turbulence-reducing bubble plate and an oversized air silencer for near-silent operation. For those looking for an external filtration solution that doesn't compromise on power, the SRO 5000EXT is the industry standard.

Key Features
