4. FoamView The FoamView window built into the front of the collection cup provides a clear view of the foam ingaction inside the skimmer neck and allows for easy and accurate adjustment for achieving the desired consistency of the foam The integrated neck washing system will keep the neck completely clear at all times Optimal compactness The ergonomic compact rectangular design of the C Skim with the complete user interface on one side of the unit makes the C Skim ideal for any conventional filtration system in sump or stand alone without compromising on skimming efficiency or performance Integrated Skimmer Neck Washing system The neck of the protein skimmer is the section where the dense air water mixture gradually transforms into dry foam Over time if not cleaned regularly a thick layer of organic sludge will form on the inside of the neck Research has shown that allowing organic sludge to accumulate in the skimmer neck will reduce foam production by 30 40 The integrated neck washing system developed for the C Skim diverts the incoming water for a short period of time from the skim chamber to an annular spray ring around the top of the neck which sprays concentrated jets of the incoming water onto the inside of the neck This washes all of the accumulated sludge back into the reaction chamber Upon returning the water flow back to the skim chamber most
5. Protein skimming also called foam fractionation can be considered as a form of fine mechanical filtration since it is a physical process of removing substances from the water Whilst a mechanical filter removes large particles such as uneaten fish food a protein skimmer removes suspended or dissolved organic waste and invisible particles from the aquarium water The advantage of protein skimming lies in the fact that waste material is continuously removed separating it from the water flow The waste suspended in foam is then collected into a cup where it is no longer in contact with the aquarium water In contrast the dirt collected in an ordinary mechanical filter stays in contact with the water flow A mechanical filter should therefore be cleaned very regularly otherwise bacteria will decompose the collected dirt into harmful dissolved organic material A successful marine aquarium should have both a regularly cleaned mechanical filter and an efficient protein skimmer as the first and second stage of the water treatment process Why is protein skimming important Protein skimming plays a very important role in reducing the amount of dissolved organic material in your aquarium water This material consists of protein carbohydrate and fat fragments together with other waste produced by the living organisms in the marine aquarium Since these could break down to potentially harmful materials to the aquarium inhabitants rapid remov
