Are you looking for the perfect sump that incorporates the Best Fleece Roller mat available, the Clarisea SK5000? The Synergy Reef® SK-60 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 rollermats. This allows for high flow systems up to 2600 GPH with 2 SK5000s! 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 roller mat 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 60″ models are designed to provide the best functionality on your system. You will need to purchase the SK5000 fleece filter separately.

Since this sump has a Refugium built in, you get the added benefit of the Refugium removing nitrates for you. So 2 mechanical filtration sections (Socks & Skimmer) and a Refugium.  We recommend this sump for tanks up to 300 Gallons. With 2 SK5000s there is a maximum flow rate of 2600 gph thru the sump.

These are available in left to right flow or right to left flow. Please select the option.

So clean🔥

Amazing craftsmanship. I’m very happy with the sump and ATO reservoir. Beautiful and functional.

Awesome Sump!

I bought my sk60 about a year ago and it has been unbelievable! The craftsmanship on it is top knotch! The only thing I've had a problem with was I broke the adapter plates for the sk 5000's but honestly I them sitting on the bottom plate and the tubes screw right in to the bulk heads like there supposed to. I love my purchases with Synergy. Everything I've bought from them are awesome products! Next time I need a sump, overflow,ATO container or anything acrylic,they will be my first call!

World Class Manufacturer - Highly Recommend SK-60 Clarissa SK5000 Sump

I ordered the SK-60 with a few custom specifications and I was very impressed with the responsiveness and professionalism during the order process answering questions before the order through email. I was also very impressed because they quoted 8-10 weeks to ship, and shipped in 8 weeks even during the COVID supply chain disruptions while many companies were not hitting quoted timelines. Once I received the product, I somehow cracked one of the adapter plates for the Clarissa SK-5000 roller mats and they replaced it promptly, with excellent customer service. As far as the sump itself goes, every part of it is superior quality and carefully designed for perfect function. The products from Synergy are worth every dollar!!!
