Compact Filtration for Aquariums Ranging from 40-80 Gallons

Footprint: 4.5" x 7.5" | Reaction Chamber: 4" | Height: 19"
Pump: IceCap EVair 400

Modern Design and Functionality

The IceCap K1 100 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 skimmers on the market miss out.

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 entirely for secure service.

Quiet Performance & Control

At the Core of the IceCap K1, you will find the IceCap EVair 400 skimmer pump built to be highly durable and packing a ton of efficient performance. It's comfortable to grip and twist-Locking access to the pinwheel for secure service.

The pipeless output offers fine-tuning and trouble-free underwater outflow plus quiet operation. 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.

Bioload Handling

The bioload of an aquarium refers to its ability to process waste in proportion to tank volume. Protein skimmers perform best when the aquarium's bioload matches the bioload rating suggested by the skimmer manufacturer.
