  • Buy next size up By Mike Greene on 8/18/2014

    I 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 7/8/2014

    I 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 6/25/2014

    I 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 5/30/2014

    Not 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.
