Very impressive

Given its superior quality, customizable color options, and robust functionality, the Synergy Reef sump is highly recommended for a stylish and efficient filtration system.

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

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!

Great overflow

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.

Socks and silencers

The socks and silencers are great like I expected. Knew I wouldn’t be disappointed since I have had a great experience with my synergy reef sump and overflow. Thanks!
