Collection: IceCap Protein Skimmers

IceCap lists four protein skimmers across two lines. The K1 Nano and K1 Neo sit at the compact end of the range and are aimed at small systems. The AIO-120 and AIO-240 are named for all-in-one aquariums, where a skimmer has to fit inside a rear filtration chamber rather than stand in an open sump. The number separates the two AIO sizes from one another. On an all-in-one the compartment decides what will physically fit, so measure the depth and width of the chamber before choosing between the 120 and the 240.
