| 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, an integrated Neck Washing system which increases long term skimming performances and the FoamView™ enabling easy adjustment of the skimming foam production.
Inlet: Aquarium water is injected above the conical top of the skim chamber which spreads the incoming water flow around the periphery of the skim chamber walls, preventing turbulent flows of water that can destabilize the foam production.
Aeration: The aspiration pump with pin wheel impeller re-circulates the water in the chamber while constantly injecting 800 liters (200 gal) per hour of micro air bubbles into the water.
Foaming: The conical top of the skimming chamber concentrates the air/water mixture, forcing it up into the neck of the collection cup where it transforms into dry organics-laden foam.
Outlet: The out-flowing water is collected evenly from around the periphery of the bottom of the skim chamber where it is almost bubble free.
Control: A skim regulator valve easily adjusts the foaming for a wide range of water conditions providing optimal skimming performance.
Integrated 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.
FoamViewTM
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.
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 & FoamViewTM Window, Air Control Valve with Silencer, Skim/Wash Control, Aspiration Pump, Waste Drain Port, 90º Outlet Adaptor suitable for standard 40mm or 1-1/2" rigid pipe.

 "Red Sea C-Skim 1200 Advanced Protein Skimmer")
The Red Sea C-Skim 1800 is the easiest-to-maintain advanced protein skimmer on the market, introducing commercial features at a hobbyist price. Designed for placement in or next to a sump, the C-Skim 1800 can be powered by your aquarium main flow pump or 400 gph separate pump. A dedicated closed loop aspiration pump gives over 200 gallons per hour of air, creating a true water-to-air ratio exceeding 3-to-1. Its compact square footprint maximizes sump space, while all controls are on one face, making setup and maintenance a breeze. Regulate foam height easily using an integrated adjustment lever and patented "FoamView™" window. A 3-position lever on the same face allows you to lower water levels for routine maintenance without unplugging pumps or uncoupling any fittings. Or flip the lever down to engage the C-Skim's innovative neck washing system. Performed daily, this feature increases skimmer efficiency by over 40%, ensuring peak performance! Built-in drain plug fitting means you never have to remove the collection cup. Aspiration pump included. 13.4" x 10" x 21-1/4"
