Versatile. Spacious. Accessible Filtration. The IceCap 24 Reef Sump V2 was developed and built around the requirements of a modern-day reef aquarist. Its attention to detail, practical design, and overall aesthetic appeal will exceed any expectations. This modern-day reef sump features a spill-over design in the micron bag compartment with compartment lids for quiet operation. The Reef Sump was constructed to adapt to your filtration needs with adjustable baffles, probe holder, and plenty of room for equipment such as skimmers, heaters, return pumps, and reactors. What changed? The IceCap 24in reef sump has undergone some changes. The freshwater reservoir has been removed and multiple 4in socks have been replaced with a single 7in sock prefilter. Additionally, new drains have been added along with a built-in holder for the heaters. It's important to note that the exterior dimensions, skimmer compartment, and return sections remain the same size between versions 1 and 2.
