Increasingly, methods are used management of the aquarium attached to the Berlin method, based on the administration of organic carbon sources (ethanol, acetic acid, vodka, or various types of sugar such as sucrose and fructose, ...) to power bacteria (mostly anaerobic or facultative anaerobes) so that they increase in number, as they are able to reduce nitrates and phosphates.
In this process the skimmer cover a fundamental role to be more efficient and skim a little 'liquid so that the package does not become dirty too quickly and the skimmer does not reduce its efficiency because it has to remove excess bacteria remaining suspended in water.
must be careful not to overdo it with these carbon sources as too high doses lead to bacterial blooms that occur with the formation of a brown flap on the surface of the aquarium, rocks, sand, ..., and with ' water becomes milky.
These bacterial blooms can lead to mortality or to anoxia, as the bacteria and then burn a lot of oxygen can also lead to bacterial diseases, or excessive nutrient reduction resulting in passage of the corals.
are management systems that should be followed carefully, but can give great satisfaction.
