Flow!!! Review by Nate
This is a great product and I'm so happy to see AquaCave carrying this line of overflows. I bought the 700 GPH overflow for my 29g nano and it can handle all the flow I will ever need. Blends perfect with the black wall of the nano and very easy to install. I used silicone and my tank was ready to go 24 hours later. (Posted on 7/8/2013)
GREAT OVERFLOW! Review by Nick
Will buy again. I finally found an overflow for my 40g frag tank. Takes up little space and installed in 10 minutes. Planning to buy a larger one for my DT. (Posted on 1/28/2013)
PERFECT FOR NANO Review by John
I bought this for my 20 gallon nano tank. Perfect size and great option for tanks with tempered glass bottoms. Thanks AquaCave! (Posted on 1/28/2013)

PERFECT PERFECT PERFECT!!! Review by John
This overflow is all about durability and functionality! Its simple, space-saving and made from thick, strong acrylic. Not flimsy thin plastic. I tend to rearrange the rock in my tank and hit the overflow pretty hard with a large piece of rock. There wasnt even a mark left let alone and serious cracks or damage. Very tough! A must have for any serious aquarist! (Posted on 1/1/2013)
