The Reef Octopus BR70 BioPellet Reactor is the smallest in the BR series, built for solid carbon dosing with biopellets on smaller reef systems. A fluidizing cone bottom keeps media suspended and evenly dispersed as water flows upward, while a durable acrylic screen at the top prevents pellets from escaping into the sump. Best for: smaller reef aquariums running biopellet-based carbon dosing Setup: requires an external feed pump plumbed to the reactor inlet (not included) Design: fluidizing cone bottom, screw-fastened lid for a secure seal, acrylic anti-clog screen This is the base BR reactor body — no integrated pump — so you'll feed it off an existing return or dedicated reactor pump rather than plugging it straight in. For a self-contained, all-in-one alternative with a built-in pump, see the BR1000SS/2000SS/3000SS Space Saver series.Compatible replacement parts: acrylic screens and cone-bottom seals for the BR70.
