Reef Octopus Super Reef SRO 6000ext Recirculating External Protein Skimmer (SRO-6000EXT)
The Reef Octopus Super Reef SRO 6000ext Recirculating External Protein Skimmer (SKU: SRO-6000EXT) is a high-capacity out-of-sump organic waste extraction system distributed by CoralVue to maintain low nutrient metrics across massive marine systems up to 700 gallons. Standard internal in-sump skimmers are continuously affected by fluctuating sump water levels, evaporation cycles, and shared chamber turbulence. The SRO-6000EXT bypasses these mechanical variables completely by utilizing a fully sealed, recirculating external framework. By drawing its internal processing volume independently via its dedicated Bubble Blaster loop, the skimmer maintains an unyielding, high-density air-stripping column that processes dissolved proteins, amino acids, and organic compounds before they can break down into nitrates and phosphates.
At the center of this heavy-duty system is the specialized Bubble Blaster HY-5000s pinwheel pump. Unlike basic utility water pumps fitted with afterthought needlewheels, the Bubble Blaster is built from the ground up for the sole purpose of air fractionating. Utilizing an ultra-hard Silicon Nitride impeller shaft and high-flux Neodymium rare-earth magnets, the pump delivers extreme rotational torque while drawing a mere 45 watts of electricity. The pump injects a massive 2,100 L/H of air directly into an integrated bubble diffusing plate at the skimmer base. This configuration eliminates harsh directional tracking, resulting in an ultra-quiet, microbubble cloud with massive total surface area that smoothly travels up the 12-inch hybrid cone body without collapsing early.
Key Features
True Recirculating Performance Advantage: Allows you to fine-tune the exact rate at which water passes through the chamber by utilizing a separate, secondary feed line or dedicated utility pump.
Integrated Internal Circuit Shutdown: Onboard digital pump circuitry checks operational resistance in real time, automatically cutting power if a jammed needlewheel or physical blockage is detected.
High-Volume Air Silencer Array: Oversized noise reduction cylinder with built-in flexible air line mounts minimizes suction noise for near-silent operation.
(Note: This external system requires a separate, dedicated feed pump or a manifold line delivering between 900 and 1,400 GPH of raw system water to function correctly).
Verified System Load Ratings
Heavy Bioload Environments: Rated for heavily populated coral reef systems up to 500 Gallons.
Medium Bioload Environments: Rated for standard mixed reef or community marine setups up to 600 Gallons.
Light Bioload Environments: Rated for sparsely populated layouts or ultra-low nutrient configurations up to 700 Gallons.
