The IceCap Nano 50 HOB Protein Skimmer is a highly efficient hang-on-back protein skimmer specifically engineered for smaller saltwater aquariums. It effectively removes organic waste and dissolved proteins from the water column, significantly enhancing water quality and clarity, which is vital for maintaining a thriving reef ecosystem. This skimmer boasts an impressively slim profile, minimizing its footprint behind the aquarium and accommodating tank rims up to a half-inch thick. Crafted from robust, high-quality acrylic, it features a quiet 12V DCair 700 skimmer pump for reliable performance. Fine-tuning the collection is simple with its easy-to-dial-in output valve, and the unit disassembles effortlessly for routine cleaning and maintenance. It is perfectly suited for aquariums up to 65 gallons with a light bioload, 40 gallons with a medium bioload, or 20 gallons with a heavy bioload. Its compact design, quiet operation, and superior waste removal capabilities make it an excellent choice for nano reef tanks or smaller setups where space is limited but pristine water conditions are paramount.
