Not every DC pump needs to be tied to a specific skimmer or reactor — sumps, filters, and closed-loop systems often just need a general-purpose controllable water pump. The Reef Octopus RODC Controllable Water Pump line offers exactly that, in two flow capacities.
Why a General-Purpose DC Pump Helps
General circulation tasks — feeding a media reactor, supplementing flow in a sump, running a closed loop — don't always call for a pump purpose-built for one job. A general-purpose controllable pump gives you flexibility to use it wherever variable-speed circulation is useful.
Choosing a Size
- RODC 3500 — a general-purpose DC circulation pump for sumps, reactors, filters, and closed-loop systems.
- RODC 5500 — the largest general-purpose DC circulation pump in the RODC line, for bigger sumps, reactors, and closed-loop demands.
Setup Tips
- Size to your total head height and application, not just tank volume.
- Use variable speed to fine-tune flow for the specific job — a reactor feed typically needs less flow than closed-loop circulation.
- Confirm plumbing fitting sizes match your intended installation before ordering.
