Ripping out "reef-ready" overflows: Bad idea?

[shelburn61]

I got a good deal on an "reef-ready" oceanic 120g with a pair of the big, black, top-to-bottom overflow boxes in each corner. Are there any benefits to this design?

I only see the negatives: less surface skimming, lost tank space, difficult maintenance, etc.

I am planning to drill the upper back corners and add 2 smaller overflow boxes. Thoughts?

I have a big overflow in my 54 wedge---I think it's also an Oceanic---and without it I'd be up a creek, with a powerful pump that really drives that overflow hard. I just barely get a downdrop. That's a big positive, the ability to take more pump. I wouldn't do it.
I let coralline overgrow mine and it makes a nice 'natural' backdrop.

You shoud have it checked. There is a chance the back my be tmepered. I left the over flow in my 75g, I just cut some of the teeth out to help with flow.

Following along. I want to setup a 120 myself and have been thinking about the different overflow options.

Was thinking of just drilling four holes in the back along the top and plumbing in overflows. The returns would be over the rim.

You should be good to go with the new holes/overflow boxes. Just be sure to cap the existing holes good if you don't plan to use them.

Definately should do it. Recently ripped the megaflops out of a buddies tank, came out great. Heres how I did mine.

Here's how they look in my tank. 0 floorspace and total surface skimming with no teeth.
