7/5/2019: I received my 4" socks today fast free shipping product is as described. one suggestion I would make is to display the socks with a black background on your site so they can standout. other then that look & feel heavy duty and will do a great job trapping crud

Thank you.

CL-26 Aquarium Sump

Awesome sump ! The build and the delivery time was excellent. The Synergy CL-26 Sump fit perfectly underneath my stand with plenty of room to maneuver. Was able to fit a Simplicity DC320 Protein Skimmer with no issues, plenty of space ! Very pleased with this sump ! Thank you SYNERGY 🤘🏻🤘🏻🤘🏻

Convenient

Layers of glue is not best sealing approach but effective. All my flow goes thru the shortest with u installed for noise. 800 gallons an hour through filter sock others just drip into sump.

Great Product

Works flawlessly for my 310gal aquariums. Only need one gate valve to fine tune the sound out of the drain. Quality product. Highly recommend.

Great ATO container

I am very pleased with my ATO container. It holds a goodly amount of RO water.

Excellent Sump at Fair Price

So I ordered a RM 34 roller mat sump that needed to be cut down to a 32”. It came in about a month and it was shipped extremely well. It took me hour to bag up all the peanuts from packaging. :) It looks amazing and while I have not installed it yet (waiting on tank) I am certain it will perform just fine! My only thought is I wish the acrylic was a little thicker but overall very happy.

Quietest overflow system!

I've been using the overflow for over a year now and am really enjoying the very low noise the box is outputting altough I am running a lot of flow through it! Surface skimmer is perfect and cleaning is very easy. Great design!

I installed this over flow on my 240 Gallon (2 X 2 X 8) tsunami aquarium. I have it plumbed into my Synergy Reef CL-60. Everything runs great. My only regret is not getting the option to replace the filter socks with a roller mat. I had to cut my CL-60's filter sock section to accept my roller mat.
