Red Sea C-Skim 1800 is said to represent “an integration of revolutionary features, performance characteristics of high demand commercial foam fractionators and the footprint and affordability of a modernly designed hobby protein skimmer.” Red Sea says it is designed for aquariums of up to 475 gallons. The skimmer can be used in both in-sump or external applications. A closed loop, 215+ GPH, PSK aspiration pump uses an all-in-one molded pin impeller to maximize efficiency and performance. Foam height can easily be adjusted via a dedicated lever. A neat feature of the Red Sea C-Skim 1800, is the ability to clean to remove the cup without having to turn off both the feed, and re-circulating pumps. Another dedicated lever is simply moved to the “cap removal position”, and the water-flow in the skimmer is reduced. The C-skim also has a drain hole that can be used to continuously drain the collection cup.

The C-skim 1800 comes with a patented neck-washing system. A turn of a lever to “wash” position will set jets of water through a spray ring, which washes the accumulated waste from the skimmer neck. This waste is skimmed out when the lever is returned to the “operating” position. This process, when performed regularly, will increase skimmer efficiency.
