Upgrade your aquarium filtration with the IceCap Reef Sump V2, available in six sizes for aquariums ranging from 10 to 350 gallons.

Designed for modern reef and marine aquariums, the IceCap Reef Sump V2 combines durable acrylic construction, quiet mechanical filtration, adjustable operating depth, and organized equipment compartments in one clean filtration system. Each model provides dedicated space for a protein skimmer, return pump, heaters, probes, tubing, and additional filtration equipment.

The V2 design removes the built-in freshwater reservoir found on earlier models, creating more usable space inside the sump for filtration equipment. A separate freshwater reservoir and automatic top-off system may be added based on the needs of your aquarium.

Important Sizing Information

Measure the inside of your aquarium cabinet and the cabinet-door opening before ordering. Confirm that the selected sump can pass through the opening and that adequate clearance remains above and around it for removing filter socks, servicing the protein skimmer, and accessing pumps and plumbing.

The listed aquarium ranges are general equipment-selection guidelines. Choose the appropriate sump according to the aquarium’s actual water volume, livestock load, available cabinet space, drain configuration, and planned filtration equipment.

Protein skimmers, return pumps, automatic fleece filters, freshwater reservoirs, ATO systems, heaters, controllers, plumbing, and other accessories are sold separately unless specifically stated otherwise.
