What is the concept behind a protein skimmer and why is it important?
A protein skimmer is a device that is used in both marine and freshwater aquaria. There are many types and designs of skimmers, some of which include: co-current , counter-current, venturi, and downdraft skimmers. Regardless of the design, the concept stays true. Protein skimmers are designed to do just that–skim off excess protein/toxic elements from the aquarium, and to aid in the dissolved oxygen levels of the aquarium water. In most designs, oxygen or ozone is introduced into a cylindrical tube and contacts the water. During this contact time, chemical reactions are taking place. Oxygen (O2) is an unstable molecule and wants to complete its valence shells by engaging in chemical reactions with other molecules. Even more unstable is ozone (O3), and is used by certain reef enthusiasts who have strict redox potential parameters, and require high water quality. In the process of this contact time and chemical reactions, many complex organic molecules are torn apart to form a foamy pro
