Aquarium Protein Skimmer

protein skimmerAquarium Protein Skimmer works by injecting tiny air bubbles into the aquarium water and the protein layer that forms at the surface is skimmed off and removed from the water. It is widely used in saltwater aquarium as means of mechanical separation to remove some of the organic waste and reduce the load for biological filtration. Other than protein, the skimming effect will also remove fats and trace amount of metal compounds as well. Generally, this will improve water quality considerably.

All protein skimmer operate using similar basic operation in which water will be directed through a chamber and then come into contact with high volumes of fine bubbles for maximum air/water surface contact. The bubbles, which are lighter and heavily charged will attract protein binding and then float to the surface. Currently there are two different systems, one is using the co-current flow and another is the counter-current system. A Venturi Protein Skimmer is a good example that works based on the co-current flow while Beckett Protein Skimmer is another that type that employs the counter current flow system.

Other than ensuring better water quality, buying a protein skimmer can actually save lot of money in the long run. Basically a cubic meter of water for saltwater aquarium can cost quite a lot and it’s much cheaper to treat the water than using fresh water and then increase the usage of marine salt. If you are a serious pet fish hobbyist, I would suggest getting a unit even though the price can be quite high, it is actually a worthy investment.
