Reef Sump 36 V2 - IceCap

The IceCap Reef Sump 36 V2 is purpose-built acrylic filtration for reef systems that demand more than a basic sump can offer. The layout is deliberate: a bubble-diffusing intake chamber quiets incoming flow before it reaches the filter sock section, where twin 7-inch sock holders with 200-micron prefilter socks handle mechanical filtration. Spill-over design in the micron bag compartment and included lids keep noise to a minimum and processing efficient.

The skimmer section measures 17 by 21.6 inches — enough footprint to accommodate larger in-sump skimmers including IceCap's own K1-160 and K3-160INT — while the return pump section at 9.8 by 21.6 inches leaves room for a capable return pump without crowding. Three 1.5-inch intake drains provide redundancy and flow capacity appropriate for high-turnover systems. The V2 design adds an emergency drain holder, ensuring that overflow safety plumbing can be routed cleanly inside the cabinet.

Equipment management is well thought out. A triple probe holder keeps pH, temperature, and salinity probes accessible and correctly positioned. Four slot tubing holders manage dosing lines and other small-diameter tubing without zip ties or improvised solutions. The twin heater holder keeps heaters upright and properly submerged, a detail that matters for both heater performance and longevity. Adjustable water depth between 5 and 9 inches lets you dial in the return section level to match your specific pump's intake requirements.

At 36 by 22 by 16 inches, the Reef Sump 36 V2 fits standard 36-inch aquarium cabinets while delivering working volume and section sizing comparable to much larger sumps. The blue acrylic baffles and adjustable water level bracket ship with the unit, allowing section customization without additional hardware. This sump suits reef keepers who want a clean, organized equipment bay and the flexibility to adapt as their system evolves.
