Reef Octopus BR70 Solid Carbon Dosing BioPellet Reactor
The Reef Octopus BR70 BioPellet Reactor (SKU: OCT-BR70) is a high-performance, specialized fluidizing media reactor meticulously designed to support solid carbon dosing in small to mid-sized marine and reef aquariums up to 100 gallons. Managing elevated nitrate and phosphate concentrations is a primary priority to avoid nuisance algae blooms and coral tissue issues. The BR70 provides an optimized environment for solid biodegradable polymer pellets (biopellets), functioning as a concentrated breeding ground for nutrient-consuming heterotrophic bacteria.
The defining characteristic of the BR70 is its engineered reverse-cone bottom dispersement plate. Standard, flat-bottom multi-media reactors often allow heavy polymer pellets to clump, settle, and cement together in stagnant corners, giving rise to toxic anaerobic zones. The fluidizing cone design of the BR70 naturally forces water outward and evenly upward from the very base of the 2.75-inch cylinder. This motion ensures that your entire media column remains in a continuous, active tumble without dead spots. Sealed with heavy-duty thumb flange screws and equipped with a non-restrictive upper acrylic containment screen, the BR70 offers a reliable, low-maintenance approach to establishing a clean, ultra-low nutrient aquarium ecosystem.
Key Features:
Perfect Fluidization Matrix: Combats media packing and channeling by distributing incoming flow uniformly through the lower chamber.
Durable Sieve Screen Assembly: Eliminates old-fashioned foam pads that quickly trap debris, using a sleek mesh plate to prevent media bypass.
Flexible Installation Plumb: Furnished with customizable 1/2-inch barbed fittings to instantly accommodate your existing pump feed lines.
Premium Construction Core: Hand-machined cast acrylic offers heavy structural integrity and complete optical transparency to check pellet wear.
Inline Integrity Check: Built-in design features help safeguard against accidental media back-siphoning if power is interrupted.
Bioload Handling:
Heavy Bioload: 50 Gallons
Medium Bioload: 75 Gallons
Light Bioload: 100 Gallons
Ideal For:
• Small reef tanks and nano aquariums up to 80 gallons that require consistent nutrient export.
• Hobbyists with very limited sump space who need a high-performance, vertically oriented reactor.
• Advanced nano-reef keepers who want to fine-tune their carbon dosing with a dedicated feed pump.
• Systems using solid carbon sources like Reef Octopus BioSpheres to combat nuisance algae.
• Aquarists looking for a robust, professional-grade reactor scaled for smaller water volumes.
Pro Tips:
-
Target Your Skimmer Intake. For premium nutrient reduction results, always route the outlet water exiting the BR70 directly into the same sump compartment as your protein skimmer's intake pump. The skimmer will immediately intercept and extract the bacteria-laden sludge shedding off the tumbling pellets before it can disperse back into your display tank.
-
The Phased Boot-Up Method. Never fill the reactor with the maximum recommended volume of biopellets immediately. Start your system with only 25% of the total suggested media amount. Allow 3 full weeks for the initial bacterial colony to colonize and adapt before adding small portions of fresh media every two weeks. This prevents a massive, sudden bacterial bloom that can rapidly drop your water's dissolved oxygen levels.
-
Zero Tumble is Trouble. Check on the reactor's tumble rhythm daily. Biopellet surfaces are naturally covered in a sticky bacterial biofilm. If the flow drops and the media stops tumbling for more than 24 hours, the pellets can quickly stick together into a solid clump, creating a toxic anaerobic zone. Always use a dedicated, adjustable pump to guarantee a constant, rhythmic suspension loop.
