Q. Why do I need a protein skimmer?
A. A protein skimmer is a device that mixes air with the water from your aquarium and allows the mixture to concentrate into foam where protein molecules attach and become removed. There are several methods of protein skimming of which counter-current; venturi and downdraft types are the majority. Protein skimmers are placed either in or near a sump or are hung on the back of the aquarium.

The primary benefit of a protein skimmer is its ability to remove a significant quantity of organic matter before it is broken down biologically. Another benefit is that it oxygenates the water raising your dissolved oxygen. A protein skimmer can also act as a mechanical filter to a small degree by removing some particulate matter.

At the Marine Scene we strongly suggest the use of protein skimmers on all typical aquariums. A veteran aquarist that fully understands the careful chemical balance in an aquarium and who has the experience to visually assess his or her aquarium will often minimize or forego the use of a protein skimmer. A well developed reef tank with a minimal fish load and considerable use of soft corals can often go without a skimmer at all. Furthermore, regular water changes can also minimize or eliminate the need for a skimmer. Ultimately the choice is based on overall water quality and the aquarist's ability to maintain his or her tank as desired.

Be cautious in selecting a protein skimmer. There are many types and models out there. The key is to get the unit that is properly matched to your aquariums needs.
