Protein skimming only works with saltwater tanks. It's primarily used by reef aquarists, but it's also the best method of mechanical filtration for saltwater fish only tanks. Visit the section for an overview of how protein skimming fits into an overall filtration strategy. For more serious aquarium keepers with have the advanced venturi marine skimmers made by the highly regarded European company; Tropic Marine Center.

The majority of unwanted organic wastes found in our aquariums collect at the surface of a gas-liquid interface. These "surface-active" materials, including fish wastes, uneaten food, and decomposing matter are what we attribute to increasing our tanks pollution. We associate this extra waste with increases in nuisance algaes, cyanobacterial blooms, and having a generally unhealthy tank appearance. Therefore, when we add new fish, and/or increase the volume of foods in our tank, we hope to remove an equal amount of potential pollution. The good news is we can reduce some of these potential wastes by removing them from the water before they cause problems. One method of removing organic wastes from a fish tank is through foam fractionation (skimming). I have run many marine fish only and reef aquariums with and without protein skimmers for many years. To this day I can not say that there is a noticeable benefit running a protein skimmer. I ran a protein skimmer for many years on a fish only system and then I took it off the system. The system was ran for years without a protein skimmer and there was no noticeable affect on fish health. I have also set up many reef systems without protein skimmers, and had excellent results with small polypstony (SPS) corals growing very well, and several species of marine fish spawning. Some reef system setups had undetectable nitrate levels after being set up for years.The protein skimmer originated in the wastewater treatment industry many years ago. It was used primarily to reduce the organic load before the water reached the activated sludge reactors. This technique exploits the affinity of organic waste to adsorb to air bubbles. In basic terms, organic-waste-laden aquarium water is reacted in a column of air bubbles, the waste sticks in the foam, and the foam collected. Foam is what is produced when one passes a gas through a liquid that contains high levels of surfactants.
Air driven counter-current (CC) skimmers
Air driven skimmers are the original type of skimmer designed for the home aquarium, and fortunately they are one of the most efficient. However, they also require the most frequent maintenance, and can be costly. These skimmers use wooden air diffusers and a powerful air pump to produce their bubbles. These skimmers have excellent foam volume and consistency when operated with new (unclogged) airstones. According to Theil [4], the minimum recommended height of an air driven CC skimmer is 28", and this skimmer should have two to three air woods (airstones) for every 4" of skimmer width. Therefore, a 6" diameter skimmer should have four to six air woods. Depending on the organic load of the tank, airstones should be replaced monthly to every two months, and air pump diaphragms checked and replaced when weakened. His reasoning for a minimum height of a CC skimmer is due to the fact that the water and air bubbles must interact over a set distance and time, and a skimmer shorter than 28" does not meet these criteria. Long-time hobbyists consider this skimmer type to produce the most consistent quality foam. Interestingly, this skimmer style strictly adheres to our "skimming laws," and when tuned properly it seems to yield the best results. This is a common skimmer for DIY'ers, as this skimmer is easy to construct and requires minimal construction skills.
