IceCap AIO 120 All-In-One Nano Protein Skimmer (IC-AIO120)The IceCap AIO 120 Protein Skimmer (SKU: IC-AIO120) is a high-performance, ultra-compact nano waste extraction system distributed by CoralVue to bring advanced direct-current foam fractionation into rear-compartment filtration layouts. Standard protein skimmers feature sprawling circular footprints and wide plumbing gates that are impossible to fit into the cramped rear chambers of all-in-one desktop aquariums. The IC-AIO120 bypasses these physical limits completely by utilizing a spacesaving square body profile. This allows nano hobbyists to aggressively manage dissolved organic compounds, fish waste, and organic lipids before they can break down into troublesome nitrates and phosphates.Beneath the clear acrylic faceplates of the AIO 120 sits the controllable DCAIR-200 DC pinwheel pump. Running on safe, low-voltage 12V current, this compact engine draws a meager 5 watts of power while pulling a highly efficient 100 liters of air per hour directly into the water column. The pre-installed inline controller puts full fine-tuning power at your fingertips, allowing you to instantly ramp the pump's rotational speed up or down to accommodate your system's specific biological load. Combined with an easy-to-lift off collection cup and an adjustable hanging slider bracket, the AIO 120 delivers full-scale skimmer features in a package tiny enough to keep your main display pristine and uncluttered.Key Features Novel Side Output Flow Tracking: Forces water to exit lower in the reaction chamber and below the active surface line, keeping your back compartments splash-free. Durable Cell Cast Acrylic Build: High-grade polymer formulation resists yellowing and embrittlement, easily handling the rough conditions of localized saltwater filtration zones. Friction-Adjustable Cup Ring: Uses a simple, thick-gauge rubber O-ring along the neck column to smoothly change collection heights without dealing with fragile locking threads. (Note: This self-contained nano skimmer includes the main body housing, DC pump assembly, inline speed controller, air silencer, and power supply brick. Side magnetic mounts are sold separately under alternative parts layouts). Verified Biological Load Ratings Heavy Bioload Settings: Rated for intensively fed or heavily stocked nano fish systems up to 10 Gallons. Medium Bioload Settings: Rated for standard soft coral or community nano setups up to 20 Gallons. Light Bioload Settings: Rated for low-nutrient frag tanks or sparsely populated layouts up to 30 Gallons.
