Far exceeded my expectations

I bought the CL-60 Sump. I also bought the shadow overflow, and 10 gallon ATO. Everything arrived in a timely manner, and without a scratch. The quality of the sump, ATO and overflow far exceeded my expectations. All the lids (I also got a lid on the skimmer chamber) are recessed, and fit snuggly, this will help with salt creep and evaporation. I bought the atomic green color scheme, and couldn't be happier, the whole sump, and overflow just pop. If your in the market for a sump, ATO, or overflow, I highly recommend synergy reef.

Awesome quality and craftsmanship. I love this sump! Perfect size for a larger system or if you just want a large sump and have the space for it!

I used this for an in-wall build and it turned out amazing. I will definitely purchase from Synergy Reef again in the future.
