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.  Earlier Gen 2 models will require a different float switch bracket. Please let us know on checkout if you need Gen2 Brackets. These flow rates vary and we recommend running a lower flow rate for more efficient filtration. 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 plumbed directly to your drains, there is a maximum flow rate of 2600 gph thru the sump. For higher flow systems we recommend using the 7″ filter socks for best performance.

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

Just Awesome!!

I am thrilled to have received my SK-60 sump. The craftsmanship is impeccable! It looks nice and feels very sturdy. I love the flexibility I now have with the mechanical filtration options and refugium chamber.

SK-60 Beautiful Sump

I received my SK-60 a few days ago. The workmanship is excellent. All the extra parts were present. I love the look, fit and finish of the sump. The seems all look perfect. It will be nice to show my friends when it is setup.. The packaging was well done also, no damage at all. The delivery was from a lift truck to my garage, so that wasn't an issue. Even on the pallet is wasn't that heavy. As suggested I did a leak test for a couple days and everything is fine. Cant wait to hook it up and get the system going. The tank I have coming has a synergy shadow overflow, they should go nice together.

SK-60 Sump

Excellent experience from first contact! Great communication during build with several status updates. Specific instructions regarding freight delivery made the process seamless. Now, let’s get into the meat of this thing-the sump. Beautifully done and well thought out as far as design. Exceptional machining and quality parts make the build very robust. Best of all.. made in the USA by a family owned business.

Thank you for the feedback and review Abtin! Enjoy your new sump!

Top Quality Product

Quality is absolutely top notch. Great communication through out the ordering/build process with updates all along the way. Will absolutely be ordering more items for my system from them !!

expected high quality, was not disappointed

I ordered pretty much all the options for this sump. I was sick of messing around with my nice, but sort of limiting current setup. I have not yet put this sump into service but have been spending time getting it ready - pre-plumbing, getting the fleece roller installed, etc. You can imagine something, look at reviews/videos, etc and all that just sets your expectations. Seeing this in person once it arrives is totally different. This thing is impressively well built with lots of attention to detail.

While I knew the dimensions it did seem imposing when I received it. It showed up undamaged from the shipping company (don’t sign for it until you open it enough to see that it is not damaged). After moving it into the garage and removing the rest of the packaging to check it out I was impressed with how well the accessories were packaged to ensure that they didn’t break or damage other components during shipping.

A couple things to note/wish list:
- The chamber where the input pipes land is really really hard to get into. Don’t expect to retrieve anything from this chamber (a fish surfing the overflow) without some serious work unless you have extra joints and/or super small hands
- While I understand Synergys stance on not doing non-standard things, I use an external return pump and looking at this beautiful sump facing the challenge of drilling the return chamber is daunting. Is it “hard”, no but I worry about messing it up or what I do not being as well finished as the rest.
- I’d love to see some sort of internal lighting option. I looked at other high end vendors and this option really struck me as a good idea. I can’t count the number of times I needed to grab a flashlight to try to see into my current sump. I am looking for a solution to putting some sort of LED into the sump to provide some lighting without detracting from how great this looks. I’m not one of those “color changing LEDs to match my current mood linked to my iWatch” types but just having some additional light would be great.

Overall summary “wow, it was worth the wait”.
