Compact Filtration for Aquariums ranging from 40-80 Gallons

Modern Design and Functionality
The IceCap K2 50 is a remarkably compact skimmer that offers a new level of refined filtration for marine aquariums ranging from 40 to 80 gallons. All aspects of the skimmer were implemented to surpass many challenges other skimmer on the market miss out on. Compact & Built to Last

Master crafted from robust PVC and high quality acrylic. All components are marine safe and refined in every aspect to provide the latest enhancements in foam fractionation and the highest in quality.

The elegant “Beer Bottle” curve of the skimmer body naturally stabilizes the air and water mix as they transition upward within the reaction chamber. An impressively compact footprint makes it the ideal candidate for tight sump applications. Every aspect of the skimmer disassembles completely for easy service.

Quiet Performance & Control
At the Core of the IceCap K2, you will find a super efficient DCAIR-700 DC skimmer pump that packs this skimmer with tons of microbubbles.

The pipeless output offers fine-tuning and trouble free underwater outflow plus quiet operation. The wedge pipe commonly used on other skimmer to channel outgoing water often causes performance inconsistency and additional sound. Our pipeless design not only saves on space but also allows the outgoing water to exit on the side of the skimmer and below the water surface providing splash-free circulation in the sump.

Located much lower in the reaction chamber, the unique bubble dispersing chamber offers a multi stage diffusion of water, additional contact time for enhanced foam stability.
