Not every reef build has room for a custom-cut sump, and a simple, well-designed PVC sump can be exactly what a nano or small reef tank needs. The Reef Octopus RS-80 Mini Reef Sump is built with a straightforward baffle layout for easy setup.
Why a Purpose-Built Mini Sump Helps
Nano and small reef tanks benefit from the same sump advantages as larger systems — dedicated space for a skimmer, room for a heater and probes out of display view — but need a sump actually sized and priced for that scale rather than a scaled-down large-tank design.
What the RS-80 Offers
- Simple, well-built PVC construction sized for nano and small reef tanks.
- Straightforward baffle layout that's easy to understand and work with during setup.
- Room for core equipment — skimmer, heater, and probes — out of display view.
Setup Tips
- Plan your equipment layout before final plumbing, since baffle compartments define where each piece of equipment can go.
- Match overflow and return plumbing to your specific display tank's drilling or overflow box.
- Leave a stable water level range in the return section for consistent pump performance.
