Some skimmers are built to accept a specifically controllable pump rather than a bolt-on VarioS-S replacement, and the RODC line fills that role with five preset speeds and dedicated service controls. RODC Skimmer Pumps come in two sizes for compatible Reef Octopus skimmer bodies.
What Makes RODC Different
Rather than smooth variable-speed control, RODC pumps offer five discrete preset speeds selectable via LED indicator — a simpler control scheme that's easy to set and forget — plus a dedicated feed/service pause button for quick maintenance access without powering the whole pump down.
Choosing a Size
- RODC 2500s — offers five preset speeds via LED indicator, a feed/service button, and a timer function for compatible skimmer bodies.
- RODC 3500s — the larger option, with the same five preset speeds, 10-minute feed/service pause button, and timer function for bigger skimmers.
Before You Order
- Confirm compatibility with your specific skimmer model, since RODC pumps are built for particular Reef Octopus skimmer bodies.
- Use the feed/service pause during feeding or coral dosing to temporarily halt skimming without a full power cycle.
- Select a preset speed based on foam production rather than defaulting to the highest setting.
Reef Octopus RODC Skimmer Pumps are available at Marine Concept Supply in both sizes — order online or pick up at our shop in Wheeling, IL. Shop RODC 2500s or RODC 3500s, and browse more aquarium pumps.
