Octo BR3000SS Space Saver BioPellet Reactor

Biopellet Reactor for Large Reef and High-Nutrient Saltwater Systems

The Reef Octopus BR3000SS Space Saver Biopellet Reactor is the definitive solution for large-scale nutrient management where sump real estate is at a premium. Designed for systems up to 500 gallons, this reactor utilizes an ingenious internal pump configuration to minimize its overall footprint. By housing the high-performance Water Blaster 3000 pump directly within the reactor base, the BR3000SS provides professional-grade filtration volume without the sprawling floor space requirements of traditional external-pump models.

At the heart of the BR3000SS is a specialized fluidizing cone bottom that works in harmony with the Water Blaster pump to create a perfect, sustained media tumble. This constant cyclone motion ensures that every biopellet remains in suspension, maximizing the surface area available for beneficial bacteria to colonize and strip nitrates and phosphates from your aquarium water. Crafted from heavy-duty, hand-polished cell-cast acrylic, the 5.0-liter reaction chamber allows for clear monitoring of media levels and performance in even the most demanding marine environments.

Key Features:

• Space-Saving Internal Pump: Drastically reduces the required sump area by mounting the pump inside the reactor body. 
• Water Blaster 3000 Pump: Includes a premium, high-efficiency pump known for its exceptional longevity and head pressure. 
• Massive Media Capacity: Holds up to 2.5 liters of biopellet media for aggressive carbon dosing in high-volume systems. 
• Fluidizing Cone Design: The conical base plate ensures uniform water distribution and prevents biopellets from clumping at the bottom. 
• Professional Grade Construction: Crafted from durable, hand-polished acrylic for maximum clarity and structural integrity. 
• Precision Sieve Plates: Integrated internal screens keep media securely contained within the chamber regardless of flow rates.

Ideal For:

• Large-scale reef aquariums and mixed-species systems up to 500 gallons with high nutrient levels. 
• Hobbyists with complex filtration rooms where sump real estate is strictly limited. 
• High-bio-load systems requiring a massive volume of biopellet media for effective export. 
• Advanced reefers who demand a high-performance reactor paired with a top-tier, reliable pump. 
• SPS-dominant tanks where maintaining ultra-low phosphate and nitrate levels is critical for coral color.

Pro Tips:

• Feed the Skimmer. To maximize the impact of solid carbon dosing, always place the output plumbing of the BR3000SS right next to the intake pump of a powerful protein skimmer. The biological process naturally causes a heavy layer of bacterial slime to shed off the tumbling pellets. A nearby skimmer will instantly export this nutrient-laden biofilm from the system before it can break down or cloud the display.
• Avoid the "All-In" Shock. When first introducing biopellets to your aquarium, never fill the reactor to its maximum capacity immediately. Start with just 25% of the total recommended media volume. Let the bacterial colony mature for 3 full weeks before adding a small amount of new media every two weeks. This phased approach prevents a sudden, aggressive bacterial bloom that can rapidly drop the water's dissolved oxygen levels.
• Keep an Eye on the Flow. Check the fluidizing tumble of the media column daily. Biopellets are coated in a sticky bacterial matrix; if the pump intake becomes blocked by stray macroalgae or a hitchhiking snail, the pellets will stop moving and can quickly cement together into a solid block, creating an anaerobic pocket. Keep the base pump intake screen free of debris.
