The Super Reef Octopus (SRO) line is the fixed-speed workhorse of the Reef Octopus catalog — proven pinwheel pumps, straightforward operation, and a size for nearly every in-sump application. The SRO In-Sump line runs from entry-level 75-gallon tanks up through 1,000+ gallon systems.
Why Fixed-Speed SRO Still Makes Sense
Not every build needs app control and variable-speed tuning — a well-matched fixed-speed pump running a proven pinwheel design delivers consistent skimming without the added cost or complexity of DC control, which is exactly the SRO line's appeal.
Choosing a Size
- SRO 1000 — the entry point to the SRO line, sized for aquariums from 75 to 125 gallons.
- SRO 2000 — steps up to aquariums up to 200 gallons, powered by the Bubble Blaster HY-2000 pinwheel pump.
- SRO 3000 — built for aquariums up to 300 gallons, running the Bubble Blaster HY-3000 for efficient skimming.
- SRO 5000 — the top-of-line fixed-speed SRO model, rated for aquariums up to 500 gallons.
- SRO XP8000I — sits between the standard SRO 5000/6000 lines and the commercial 9000EXT, for systems that have outgrown the standard range.
Setup Tips
- Match sump depth to the model's water level requirements before ordering — larger SRO models need more clearance.
- Break in gradually, expecting microbubble overflow during the first 1–2 weeks.
- Pair with a Waste Collector for insurance during break-in or bioload changes.
