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. Available in three sizes.

These Revolutionary Media Reactors have a fluidizing cone bottom design to help keep the bio pellet media in suspension and evenly disperse the water upwards, without restricting the flow through the unit. These advanced reactor units also includes 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

Can I run GFO in this?
Question by: Osiel Alvarado on Jan 17, 2017, 10:15 PM
Hey there! I would not recommend this reactor to be used with GFO. Since the GFO particles are much smaller granular size, the downward flow from the plumbing of this reactor would not allow the water to pass underneath the media. You do need the GFO to tumble. :-)
