Biopellet reactors typically rely on flow alone to tumble media, but that can leave pellets clumping or channeling rather than staying evenly suspended. The Reef Octopus BioChurn line uses a patent-pending churn plate to actively fluidize media in a gentle cyclone motion, available as an in-sump hang-on-back or a dedicated external unit.
Why a Churn Plate Beats Flow Alone
Standard biopellet reactors depend entirely on upward flow to keep media suspended, which can result in uneven tumbling or dead zones where pellets settle and clump. BioChurn's churn plate actively drives a cyclone motion that keeps media consistently in suspension.
Choosing a Configuration
- BioChurn 90INT with HOB Bracket — uses the churn plate design with a bracket for hang-on-back mounting on the sump.
- BioChurn 90ext — the dedicated hang-on-back version, using the same churn plate for consistent media fluidization.
Setup Tips
- Start with a conservative pellet charge and monitor for even churn before increasing.
- Watch for consistent cyclone motion — uneven tumbling suggests flow or charge adjustment is needed.
- Monitor nitrate and phosphate while dialing in the reactor for your bioload.
