Has anyone installed one of these overflows?


New member
I am getting ready to start my 300 gallon build out. The tank doesn't have any built in overflows. (see pic)

Since this will be a reef tank, I am wanting to have Internal overflows. I found this one for sale at BRS


Aquarium Overflow - Overflow Box 2400 GPH
18 1/4" W x 4" D x 5" H
Recommended tank size: 150+ gallons
1/4" Black Cast Acrylic
Recommended return pump of 2400 GPH or less

Is this the best solution?
If this is the best solution, should I install two of them?
My 300 Gallon is 10' Long, by 2' Tall and 2' deep.
