General information
Marine aquarium inhabitants produce waste substances, the quantity depends on the livestock and the feeding. By means of an effective skimming system, organic waste matter, the so-called DOCs (Dissolved Organic Carbons), can be removed. To mention but a few, these are substances such as proteins, cellulose, dead cell substances from bacterial and algae. In high concentration they are harmful for any aquarium biotope. The DOC skimmer removes these compounds effectively from the water circuit, better than a bio-mechanical filter, which means that by removing proteins “before” bacterial decomposition, crystal-clear water is retained and a rise in nitrate and phosphate is reduced.
It can be observed that when air bubbles are produced proteins are absorbed immediately. In practice it can be observed that the absorbed matter is torn off the air bubbles again by skimmers with a tall reaction chamber. For this reason, all TUNZE® DOC skimmers have very short reactors with a high air throughput .
