Buy next size up By Mike Greene on 8/18/2014Mike Greene wouldn't recommend this product to a friendI ended up having to return for the next size larger. The cut out teeth seem to minimize the amount of water the overflow can handle. Just plan to go a size larger and you should be fine.
Restricted Flow By Jon Baxter on 7/8/2014Jon Baxter wouldn't recommend this product to a friendI bought the RSS12 for my 75 gallon SPS Reef tank along with a Mag12 (1200 gph) return pump. With a 5 foot head the pump is probably pushing around 900-1000 gph. It was obvious right off the bat that the overflow could not handle the flow. I would recommend buying one size up to compensate for the calculation flaw.
I also wanted to address some of the negative reviews I read on these overflow boxes. The material is not completely rigid but strong enough. I have only had my hands on the Medium size so this may be more of a problem with the larger sizes.
Great product worth the money By AJ on 6/25/2014AJ would recommend this product to a friendI purchased the Small overflow for my build. It went on easy and looks great. Wishing i went a little bigger, but i'm excited for the way it will work compared to the HOB overflow i have been using.
Confused about prior reviews By Andrew on 5/30/2014Andrew would recommend this product to a friendNot exactly sure about the above reviews. If you will notice, they are all posted on the same day. I ordered this (RSS12) because everything else was out of stock and thought i would take a chance. I am more than happy. It is 3/8" thick black acrylic, not flimsy at all. Nice quality.

What size goes with the 700 overflow lid?
Bulk Reef Supply Hi Evan,
The 700 lid measures 3"x3" and we do not currently stock an overflow box that size. Our smallest overflow box is the RSS05. Its measurements are - 6 3/8" L x 2 3/8" W x 3 5/8" H. The RSS05DX is very similar but it has a back on the overflox - 6 3/8" L x 2 5/8" W x 3 5/8" H.
I hope this helps.
Have a great day :)
