All skimmers work in the same way, but there are different designs that have developed over the years. These include co-current, counter-current, venturi-style, and ETS skimmers. Each works in a slightly different manner. Protein skimmers are often a good choice for keeping your saltwater aquarium clean. Besides primary biological filtration, foam fractionating (better known as protein skimming) is the most important aspect of any healthy marine system.
Although there are systems that claim to be “skimmer-free,” for most of us, dissolved organic compounds (DOC), phenol oils, and other yellowing agents are a nuisance. Only active protein skimming can eliminate the need for these. It is also important to understand that different manufacturers put their own twist on the basic design. While your choices in a skimmer are vast, it remains important to understand their basic function.
Protein skimmers help maintain low nitrate levels by retarding nitrate buildup. They remove organic waste before it has a chance to break down and release nitrogen compounds. The use of a protein skimmer is essential in reef aquariums where a very low nitrate level is crucial for coral health.
We have adding an new protein skimmer into our soft coral facility to improve the quality of our soft corals. Moving together with the new technologies and ideas in aquaculture for improved quality is beneficial to all industry players. This is an indication of how Kenya Marine Center takes serious measure to improve its quality assurance.
