Adding Glass-Holes overflow kit

[jim2083]

Looking to get some opinions on adding a 1500gph overflow kit to my reef-ready 90 gallon Marineland Corner-flo aquarium.

I am looking to increase the overall turnover rate inside the aquarium.

Has anyone done this in the past?

I have the 3000 kit and I'm pretty unhappy with it. I've had to modify it after the water was in the tank to turn it into a herbie, and that was a huge pain, but I've gotten it pretty silent finally. In retrospect I should have just had a simple herbie built, either internally or externally.

Did you add it to a tank that was already drilled or is it the only overflow you have on your tank?

It's the only overflow on the tank.

Would it be too difficult to match the flow through the drains
