Full Details

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.

  • Great Biopellet Reactor By Steve on 4/10/2017

    The BR-70 reactor was a huge improvement over various media reactors I tried to use for biopellets, well worth the price. Purpose built design provides great tumbling action at a reasonably low flow rate. Note the actual load capacity is 300 ml; it works great at that volume, going slightly over capacity seemed OK at first, but would eventually start to bind.
    The reactor fit perfectly in my setup, requiring only a small section of PVC pipe to connect to my manifold. I can't really give credit to Reef Octopus for that happy accident, but they do offer several options to connect both input and output, I wish more products would do the same.
    Only dislike I have was the screen at the top of reactor; it is changed from picture here, now a clear plastic grate on a collar that is held in place with a plastic bolt. The grate itself is fine, but tightening the bolt is an exercise in frustration, especially when it seems the bolt wouldn't even be necessary if they just made the collar a little taller. Rather than mess with the bolt one more time, I made a spacer out of PVC pipe to fill the gap that should have been collar, seems to work fine.
