IceCap AIO Protein Skimmer

The IceCap AIO Protein Skimmer is a compact, air-driven skimmer built to drop into the rear filtration chamber of All-In-One (AIO) reef tanks. It pulls dissolved organic waste out of the water before it can break down into nitrate and phosphate, which helps keep the water cleaner and your corals happier. A quiet DC air pump drives it, and the small footprint is made to fit the tight back chambers AIO tanks are known for. Round out the system with the rest of your saltwater and reef supplies.

How It Works

The DC air pump feeds a steady stream of fine bubbles up through the skimmer body. As the bubbles rise, dissolved proteins and organic waste cling to their surface and collect as foam. That foam climbs into the removable cup at the top, lifting the waste out of your tank before it has a chance to decay and drive up nutrients.

Why Reefkeepers Like It

• Compact footprint sized for the back chamber of AIO nano and reef tanks
• Quiet, energy-efficient DC air pump
• Removes organic waste before it becomes nitrate and phosphate
• Removable collection cup makes cleanout quick
• Simple drop-in setup, no sump or extra plumbing required

Choose Your Size

Both models are the same air-driven design; pick the one matched to your tank volume and the space in your back chamber.

FAQ

Which size do I need? Match it to your display: the AIO 120 suits 10 to 30 gallon AIO tanks, the AIO 240 suits 20 to 65 gallon AIO tanks. If you sit between two ranges or run a heavier bioload, size up.

Does it need a controller? No. The DC air pump runs the skimmer on its own, so it works right out of the box.

Will it fit my tank? It is designed for the rear filtration chamber of All-In-One tanks. Check the footprint and height above against the open space in your back chamber before ordering.

Freshwater or saltwater? Saltwater and reef only. Protein skimming relies on salt water to form the foam that carries waste out.

Is it loud? No. The DC air pump is designed to run quietly, which matters on a nano tank that is often in a living space.
