Strong Overflow By Timmy on 4/17/13
Timmy would recommend this product to a friendThis 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
Matt would recommend this product to a friendLooks 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. -

Perfect for 110G By Robby on 10/23/12
Robby would recommend this product to a friendThis 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
Nancy P would recommend this product to a friendFinally 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! -

Nicholas would recommend this product to a friendOnly overflow box I've used but the craftsmenship is great and water tight. Measurements of the box are outside dimensions(not inside) -
Will buy again By Reef-a-holic on 5/30/12
Reef-a-holic would recommend this product to a friendI purchased this overflow for my 110 gallon reef aquarium to replace my CPR overflow. It was easy to install and so far has been working great. Plan to buy the lid and a smaller overflow for my frag tank. -
