BR140 BioPellet Reactor

The Reef Octopus BR140 BioPellet Reactor is the largest body in the base BR series, built with a cone-bottom design for larger reef systems running a substantial biopellet charge. The taller chamber gives media more vertical room to fluidize evenly, which matters as pellet volume increases. Best for: larger reef aquariums running biopellet-based carbon dosing Setup: requires an external feed pump plumbed to the reactor inlet (not included) Design: cone-bottom fluidizing base, screw-fastened lid, acrylic anti-clog screen As the top of the base BR line, the 140 is where most hobbyists land before considering a self-contained, pump-included model like the BR3000SS for larger media volumes. Compatible replacement parts: acrylic screens and cone-bottom seals for the BR140.
