BioChurn 90INT Reactor with HOB Bracket

The Reef Octopus BioChurn 90INT Reactor with HOB Bracket uses a patent-pending churn plate to fluidize biopellet media in a gentle cyclone motion instead of blasting it with direct flow pressure — a gentler, more even alternative to standard fluidized reactors. It ships with both a sump mounting option and a hang-on-back bracket, so it adapts to whichever setup you're running.

• Best for: hobbyists wanting a simple, low-maintenance biopellet reactor with mounting flexibility
• Setup: in-sump or hang-on-back (bracket included), integrated Aquatrance pump feeds and disperses media
• Design: cascading chamber for greater bacterial surface area, patent-pending churn plate for extended media contact time

The churn-style motion is the core BioChurn advantage: instead of high flow blasting pellets around (which can grind media and shorten its working life), the churn plate keeps pellets gently suspended for longer, more complete contact with tank water.

Compatible replacement parts: Aquatrance pump kits and churn plates for the BioChurn 90 series.
