  • 75gal By Roger on 3/18/14

    Put it on my 75 gallon tank. Easy install works great
  • Great quality By Bryan on 2/3/14

    Installed this on my 100 gallon tank with 1.5" bulkheads. VERY tight fit with the 90 degree elbows inside the overflow so I had to modify the fittings, but after that they work great.
  • Great overflow By Scott on 11/24/13

    Looks great in the tank. Very well made. A schedule 80 bulkhead and a downward turned elbow fits perfectly in the box.
  • Super Simple By Lisa on 7/8/13

    This Overflow has made my DIY plumbing super simple. Pretty much silicone n play. It's really that easy!
  • Strong Overflow By Timmy on 4/17/13

    This is a strong overflow. It's made from 1/4" acrylic and will stand the test of time for sure. Great product.
  • 1800GPH Overflow By Matt on 4/6/13

    Looks great! It's the best overflow I could find on the web. The only negative is the inside depth is 3 7/16". It's a tight fit with a SCH 80 bulkhead connected to a PVC elbow.
  • Two Thumbs Up! By PJ on 1/1/13

    I give this weir two thumbs up for easy of installation and durability. Made from thick strong acrylic.
  • Perfect for 110G By Robby on 10/23/12

    This overflow fits my 110 gallon aquarium perfect. Allows for tons of flow. My tank has a tempered bottom. This overflow allowed me to drill the back wall of my tank. I will most likely go with this style of overflow for all future setups.
  • Finally! By Nancy P on 9/16/12

    Finally there's an affordable option for internal overflows! As others already mentioned this overflow installs in minutes. Easy as 1-2-3... Great quality, made from sturdy acrylic. I have no doubt this overflow box will outlast my tank. Also keep in mind that if you ever had to adjust or make any repairs, you only have to drain off the first 5" of water in your tank vs. completely emptying your tank. This is a HUGE plus in my eyes!
  • good overflow By Nicholas on 6/1/12

    Only overflow box I've used but the craftsmenship is great and water tight. Measurements of the box are outside dimensions(not inside)
