Coralife Cone Skimmer's advanced design concentrates the foam as it rises, for more efficient skimming action. The micro-bubbles formed in the lower end of the column attach to organic proteins in your aquarium water. As the bubbles rise, the drier more concentrated foam is carried to the collection cup. Cone Skimmers include a powerful and quiet internal pump, a large neck for efficient foam production and control, and a patented Needle Wheel aspiration system.
