TMC Reef Bio React 2.0 – Biological Nutrient Control
The TMC Reef Bio React 2.0 is a fluidised media reactor designed to support biological nutrient reduction in marine aquariums. Available in Small and Medium sizes, it keeps compatible biopellets moving so aquarium water can circulate around them, supporting the bacteria involved in nutrient uptake.
Why Use a Biopellet Reactor?
In reef aquariums, excessive nitrate and phosphate can contribute to nuisance algae and make nutrient management more difficult. Biopellets provide an organic carbon source for bacteria, which use dissolved nutrients as they grow. A reactor helps maintain the water movement these pellets need to work effectively.
Designed for Consistent Media Movement
The Reef Bio React 2.0 is designed to circulate water through fluidised media, reducing the risk of pellets settling and clumping together. Consistent movement helps expose the media to aquarium water and supports stable operation.
The reactor is intended for compatible biological filtration media rather than serving as a universal replacement for every type of chemical media reactor. Follow the instructions for your chosen media and avoid overfilling the chamber.
Practical Installation and Maintenance
Its compact format makes the Reef Bio React suitable for installation in an appropriate sump compartment. Routine checks and cleaning help keep the reactor free from obstructions and maintain good media movement. Replenish pellets gradually as they are consumed, following the media manufacturer's guidance.
For marine systems, positioning the reactor outlet near the protein skimmer intake can help remove bacterial biomass. Start with a conservative media quantity and monitor nutrient levels, livestock and water clarity as the system establishes.
Choose Your Model
Small (S): A compact choice where sump space and media requirements are limited.
Medium (M): A larger option for aquariums needing greater biological media capacity.
Choose the model based on your system's nutrient load, available space and the manufacturer's guidance. See the Technical Information tab for individual model specifications.
Why Choose the TMC Reef Bio React 2.0?
If you're looking for a dedicated way to run compatible biopellets, the Reef Bio React 2.0 offers a practical route to biological nutrient management, with a choice of two sizes.
Available from Rock ’N’ Critters. Check the selected model's package contents and choose compatible media before ordering.
