IceCap K3 100HOB Protein Skimmer


Up to 140 gallons

Convenient and Function Design

The IceCap K3 100HOB Protein Skimmer is a compact hang-on-back protein skimmer ideal for aquariums up to 140 gallons. The shape of the skimmer body requires minimal space behind the aquarium and its pump is mounted externally for less heat-to-water exchange. 

Built to Last

The IceCap HOB DC body is constructed of high-quality acrylic and equipped with the new controllable and efficient DCAIR pinwheel pump that produces an ideal mix of water and air for optimal waste removal at the push of a button.

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.
