240 All-In-One Aquarium Protein Skimmer - IceCap

The IceCap AIO 240 Protein Skimmer was purpose-built for the rear filter compartments common to all-in-one aquariums. Rather than adapting a sump skimmer to an awkward space, the AIO 240's square body and compact 2.75" × 3.625" footprint fit cleanly in tight chambers without dominating the available real estate. An adjustable height hanging bracket means you can set the skimmer at the correct water depth for your specific tank and fine-tune it as water levels shift—an often-overlooked factor that has an outsized effect on skimmate quality.

At the heart of the skimmer is IceCap's 12V DCair 400 pinwheel pump, which draws approximately 150 lph of air and moves water at roughly 53 gph while consuming only 6 watts. DC operation keeps noise to a minimum and allows the inline speed controller to modulate pump output without the coarse, on/off behavior of AC pumps. The bubble dispersant chamber and purpose-designed output flow path help produce consistent, dry foam rather than the wet, watery skimmate that plagues undersized or mismatched skimmers.

Bioload rating is straightforward: the AIO 240 handles a lightly stocked 65-gallon system, a medium-stocked 45-gallon, or a heavily stocked 20-gallon. Match the skimmer to your actual feeding and stocking levels rather than the maximum tank volume claim—overstocked or heavily fed systems should size down accordingly.

Construction is acrylic throughout, with materials selected for long-term compatibility in marine environments. The collection cup lifts off without tools for routine cleaning, and the skimmer body disassembles fully for deeper maintenance. For hobbyists running AIO tanks in the 20–65 gallon range who want reliable mechanical filtration without a complicated install, the IceCap AIO 240 is a practical, well-matched solution.
