The Reef Octopus Biopellet Reactor is designed specifically for the use of solid carbon dosing biopellets. Cone bottom design helps to keep the biopellet media in suspension and evenly dispersed. Reactor lids close with fastening screws and a mesh screen contains biopellets while still allowing flow.


These Revolutionary Media Reactors have a fluidizing cone bottom design to help keep the biopellet media in suspension and evenly disperse the water upwards, without restricting the flow through the unit. These advanced reactor units also include fastening screws on the lid for a sure tight seal and a mesh screen to keep the bio pellets within the reactor without the risk of restricting flow or clogging like other media reactors on the market.

Product Questions

Do these have a check valve or something to avoid backflow causing pellets to get sucked up the intake?
Question by: Kevin Petersen on Jan 19, 2020, 11:12 AM
Hey there!

They do not have check valves but have grates and strainers in place to prevent it from backflowing any biopellets out.

Take care!
