Clarify Your Aquarium Water
Our protein skimmers inject fine bubbles into the water that attract and bind to organic pollutants in your aquarium. This creates a dense foam that is further concentrated by the hybrid cone as it is carried into the collection cup, thereby, removing the waste to improve water quality to create a healthier reef ecosystem.
Remove Waste Efficiently
Our uniquely designed air intake valve pulls in more air than more expensive competitors, producing a dense waste-removing foam. The hybrid cone body then stabilizes the foam column and concentrates it as it rises, maximizing waste removal through foam fractionation.
