Are you looking for the perfect sump that incorporates the Best Rollermat available, the Clarisea SK5000? The Synergy Reef® SK-44 model sumps are your answer. We have designed this sump to be able to run 1 or 2 Clarisea SK5000 Gen2, Gen 2.1 or Gen3 Fleece filters. Earlier Gen 2 models will require a different float switch bracket. Please let us know on checkout if you need Gen2 Brackets. Very easy to drop in your Clarisea SK5000 and get running. No Modifications needed and will not void your Clarisea warranty. You can also run filter socks on this sump in tandem with the SK5000. Or if you want to just run 7″ or 4″ filter socks, that can be done as well. This is a universal sump that will allow multiple configurations and not be obsolete like other rollermat sumps that are built into the sump. These are hand-built right here in the USA with only the highest quality materials and craftsmanship. Our 44″ models are designed to provide the best functionality on your system. You will need to purchase the SK5000 fleece filter separately.

Refugium is not available on this sump due to the larger area needed for the ClariSea fleece filter. Our CL44.4 Sump will have a refugium option if needed.
