C- Skim (1800 liters):

Red Sea C-Skim 1800 represents 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. The C-Skim provides a new level of protein skimming in terms of efficiency, performances and user friendliness.

The C-Skim features include a Peripheral Flow Closed Loop Skim Chamber providing improved water/air flow dynamics, a unique integrated Neck Washing system which increases long term skimming performances and the FoamView enabling easy adjustment of the skimming foam production.

Long Term Pollutant Reduction

Tests have shown that over time the C-Skim is extremely effective in lowering the level of oxygen consuming pollutants (COD/BOD) in aquarium water.

Integrated Skimmer Neck Washing system

Research has shown that allowing organic sludge to accumulate in the skimmer neck (which will occur if not cleaned regularly), will reduce the foam production by 30-40%. The patent pending integrated neck washing system developed specifically for the C-Skim diverts the water from the skim chamber to an annular spray ring around the top of the neck that sprays concentrated jets of water onto the inside of the neck, washing all of the accumulated sludge back into the reaction chamber. Returning the water flow back to the skim chamber flushes the sludge into the collection cup for easy disposal.

Foam View

The patent pending FoamView window built into the front of the collection cup provides a clear view of the foaming action inside the skimmer neck and allows for easy and accurate adjustment to achieve the desired consistency of the foam. The integrated neck washing system will keep the  FoamView window completely clear of organic sludge at all times.

Ergonomic Design

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 use in sump or stand-alone installation on any conventional filtration system without compromising on skimming efficiency or performance.
User interface features includes: Water Inlet and Outlet, Foam regulator & FoamView window, Air control valve with silencer, Skim/Wash control, Aspiration pump, Waste drain port, 90º outlet adaptor suitable for standard 40mm or 1½” rigid pipe.
