The IceCap K3-100 INT is a high-performance in-sump protein skimmer designed to efficiently remove dissolved organic compounds from your saltwater aquarium. By creating a dense cloud of fine microbubbles, it effectively strips proteins and other waste products from the water column before they can break down into harmful nitrates and phosphates. This process results in improved water clarity, increased oxygen levels, and a healthier overall environment for your corals and fish, making it a cornerstone of advanced marine filtration.

The K3-100 INT boasts a remarkably compact footprint of just 4.7 by 6.3 inches, with a total height of 19 inches, making it an excellent choice for sumps with limited space. Its 4-inch body diameter is engineered for maximum reaction time, while the skimmer operates optimally in a water depth of 6 to 8 inches. Built with quality materials, it features a quiet and reliable pump that produces a consistent foam head for stable and effective waste removal. The design also includes an easily adjustable output and a collection cup with a convenient drain port for simple maintenance.

This protein skimmer is perfectly suited for aquarists with nano or medium-sized reef systems. It is rated for aquariums up to 80 gallons with a light bioload, 65 gallons with a medium bioload, or 40 gallons with a heavy bioload. Its space-saving design and powerful performance make it ideal for hobbyists who want to maximize filtration efficiency in tight sump compartments without compromising on the health and stability of their delicate marine ecosystem.
