The AquaMaxx BioMaxx BioPellet Reactor is a finely-tuned fluidized filter designed to help hobbyists remove nitrates and phosphates from reef aquarium systems. Controlling nutrients inside our aquariums is one of the keys to preventing nuisance algae growth. AquaMaxx BioMaxx bio pellet reactors are computer designed, precision-cut and made of polished A-class acrylic. All AquaMaxx media reactors are rigorously tested to ensure reliability, efficiency and affordability. The AquaMaxx Bio Pellet Reactor utilizes a fluidizing plate to keep biopellet media suspended and evenly dispersed. The upward flow design provides maximum contact time between your aquarium water and the bio pellets inside the reactor. The Aquamaxx BioMaxx Biopellets Reactor also includes a special plate on the lid to keep media within the reactor without the need for sponges.



  • A-class acrylic construction
  • Extremely efficient, reliable and affordable
  • Easy to setup and maintain
  • Ideal for nitrate and phosphate removal
  • Instruction manual with diagrams for setup and maintenance included
  • Inlet and outlet hose fittings for ¾" flexible tubing included.

Adding a bio pellets reactor to your reef aquarium filtration system will improve the water quality for fish and other marine life. Biopellets initiate a more efficient denitrification process that removes nitrate and phosphate from aquarium water to prevent algae growth or harm to invertebrate and coral.

The AquaMaxx BioMaxx BioPellet Reactor requires a small pump/powerhead and tubing to push water through the reactor (sold separately). You can plumb the reactor using ¾" flexible tubing. Using a ball valve is highly recommended because it will allow you to dial-in the correct flow rate. A flow rate of 200-300 gallons per hour (GPH) is recommended for the AquaMaxx BioPellet Reactor. A flow rate of 300-600 GPH is recommended for the AquaMaxx BioMaxx XL BioPellet Reactor. Exact flow rates required to tumble the media will vary based on how much media is being used.

An optional hang-on adaptor (sold separately) is available for additional mounting configurations. For best results, use BRS Bulk Biopellets or similar biofiltration & nutrient control filter media.

All AquaMaxx products carry a 90-day manufacturer warranty and include detailed instructions and diagrams to help hobbyists get up and running immediately.

Could I use this product if I have a canister filter?
Question by: Caleb on Nov 15, 2021, 7:21 PM
Hi, Thank you for your question, for best performance it is better to run a separate dedicated pump for the reactor. However;
, if you plan to connect the reactor in-line using the canister filter then please consider that the reactor has a recommended water flow rate of 300-600 GPH. If the canister filter is your only filtration, please also keep in mind that depending on the flow rate and the amount of biopellets used, you may need to decrease or increase the flow rate and that can affect the performance of the canister filter.

Happy Reef Keeping.
