Protein Skimmers

A protein skimmer, or foam fractionator, is a device commonly used to remove dissolved organic compounds (DOC) such as food and waste particles from saltwater aquariums. Skimmers could be considered one of the most beneficial devices for the saltwater hobbyist.

Protein skimmers remove hydrophilic substances from water using air bubbles that are collected in a collection cup and thereby removed from the fish tank altogether. As air and water mix in the skimmer chamber, bubbles rise and take with them the dissolved organics that are attracted to the bubble surface skin.
