Reef Octopus BR110 Solid Carbon Dosing BioPellet Reactor
The Reef Octopus BR110 BioPellet Reactor (SKU: OCT-BR110) is a high-performance, specialized fluidizing media reactor meticulously designed to support solid carbon dosing in marine and reef aquariums up to 250 gallons. As modern reef systems encounter high bioloads, managing elevated nitrate and phosphate concentrations becomes a primary priority to avoid nuisance algae blooms and coral tissue issues. The BR110 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 BR110 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 areas, giving rise to toxic anaerobic zones. The fluidizing cone design of the BR110 naturally forces water outward and evenly upward from the very base of the 4-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 BR110 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 and 5/8-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 check valve features help safeguard against accidental media back-siphoning if power is interrupted.
Bioload Handling
Heavy Bioload: 120 Gallons

Warranty
CoralVue, Inc. hereby guarantees this product to be free from defects in material and workmanship for a period of:
- 1 Year
Warranty is activated on the date of purchase.
This Standard Limited Warranty applies and is limited as follows:
- To the product only as long as it remains in the possession of the original purchaser.
- To the product that has not been subject to accident, misuse or abuse.
- To the product that has not been modified, altered, defaced, or had repairs made or attempted by other than CoralVue, Inc.
- That CoralVue be immediately notified in writing within ten (10) days of first knowledge of defect by owner or his agent.
- That CoralVue, Inc. shall be given first opportunity to make any repairs, replacements or corrections to the defective construction within a reasonable period of time.
- Under no circumstances shall CoralVue and/or the Manufacturer be liable by virtue of this warranty or otherwise for damage to any person or property whatsoever for any special, indirect, secondary or consequential damages of any nature however arising out of the use or inability to use because of the product defect.
- Loosen the upper thumb-fastening hardware and lift the heavy-duty lid off the 4-inch acrylic reactor tower.
- Pour your preferred solid carbon biopellet media (CoralVue BioSphere media is highly recommended) into the main chamber body.
- Re-seat the lid flange and integrated rubber O-ring securely back onto the upper collar, turning the fastening screws down evenly.
- Connect an external, controllable feed pump (capable of pushing 530–800 GPH) to the dedicated bottom inlet plumbing using the provided union barb fittings.
- Route the upper discharge plumbing line safely back into your sump system, ensuring it drops near your protein skimmer.
- Activate the water feed pump, and adjust your inline plumbing valve until the biopellet column achieves a uniform, lively suspension tumble.
Pro Tips:
- Target Your Skimmer Intake. For premium nutrient reduction results, always route the outlet water exiting the BR110 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.
