The IceCap OVP In-Sump Protein Skimmer is engineered for marine aquariums, providing exceptional filtration performance with a remarkably small footprint. This innovative skimmer efficiently removes organic waste from the water column, significantly enhancing water quality and clarity in your reef tank. Its design specifically addresses the challenges of limited sump space, ensuring optimal air-to-water contact for superior waste extraction. Equipped with a controllable DC skimmer pump, this unit offers 10 power levels and a convenient feed timer, allowing precise tuning to your aquarium's specific bioload. Key features include quiet operation, a built-in air silencer, and a unique submerged pipeless output that minimizes turbulence for a consistent foam head. Constructed from high-quality acrylic, it is built for durability and can be completely dismantled for easy, thorough cleaning. This protein skimmer is an ideal choice for reef aquarists who require powerful filtration in a compact form factor, especially those with small sumps. With models capable of handling marine aquariums up to 650 gallons (light bioload), it suits a wide range of setups from heavily stocked to lightly loaded systems. Its robust construction and user-friendly controls make it a reliable and effective solution for maintaining pristine and stable water parameters in demanding reef environments.
