I recently bought an overflow box and drilled 2 holea in the tank. Then i realize the drain holes were inly 1/2 in for my 120g tank. Im screwed lol, so my question is what if i were to drill 1 more hole and silicone a skimmer for bean animal overflow. Does the 3 hole have to be different height? Can 2 be same hieght? Or is my tank i drilled screwed lol... sad day.

Is also possible to enlarge the holes.
Trace the inside dimension of the 1" gasket and use a slow drip of water and a dremel with a diamond bit. I have fixed small holes like this before and it's not pretty but it works.
If it is half inch glass, I would even try to use a larger hole saw but there is a huge potential for breaking the tank if you aren't square and very steady.

Well not the holes on the tank its the holes in the overflow they are 1/2 in holes. I drilled 1in holes in the glass.
I was thinking about getting a cpr retrofit overflow box.
The picture on their web site show a bean set up. Not sure how you can do this with the bulkheads extending that far into the box. They do say you can do 3/4 inch pipe in that box.

so with threaded part of the bulkhead stick out so far out there is no room or blocks the holes,for the standpipes? Now that's acrylic and a different story. Is this right?
The holes your drilled are in the overflow box. Right?
Foxt has a good idea. Maybe a bigger box.

You can trim the bulkeads to leave enough threads for the nut, and nothing more.The picture on their web site show a bean set up. Not sure how you can do this with the bulkheads extending that far into the box. They do say you can do 3/4 inch pipe in that box.
Its the holes inside the overflow box itself. all 3 holes are 1/2 inch im worried wont be good enough for 120g tank. I was thinking about drilling a third hole and buying a new overflow box and silicone it on to the tank.
I contacted modular marine they want me pay like 130 plus shipping to make one for the tank. Where i can buy a cpr retrofit for half the price.
Cant those are 1/2in uniseal i tried add 1/2 in bulkheads but super tight fitting barely turn it
I dont know who to sell it too lol.. but they offered to makr me one for my tank for a price looking at maybe 150 including shipping might just go with a price.
Yeah i think i just buy the overflow like they said and use stand pipes thx for your help

Since you have two holes drilled and have the bulkhead fittings, run a herbie. You won't have to have an overflow box.
Been drilling my own tanks and running herbies for years.
