If the price is right then you can always drill larger/more holes. The hole saws are pretty cheap. The holes don't have to be on the bottom either. You can drill holes in the back or sides if you want.
3/4" drains for a 220?

I bought my tank undrilled. It would have been nice to have the overflows already but it has allowed me to design my own setup. This is where I decided to use the H2Overflows because of their compact design while maintaining lots of surface skimming. It also will allow me to keep all the space that the large corner overflows usually take up.
I just can't wait to get it up and running. Lol

I have a 210 and use dual 1" durso's and it seems to be barely keeping up with the 1350GPH i have going through it, if you are having decent flow, I'd look into larger holes. Did you find out if they are dual holes in the overflows or single 3/4" ? I find it hard to believe that a RR tank would only have 1 3/4" bulkhead in each overflow. Wondering if the seller is possibly giving info wrong or something is being misunderstood.
Also, why are they running bioballs in the overflow itself? I haven't seen that done before.

Ya I find it hard to believe that it is only drilled with only 2- 3/4" overflows. The seller said he used a 900 gph hour pump and he used it as a reef tank.
I'm considering drilling it but the glass is 3/4" thick. Seems like a big job.

My 220 is about 5/8" (I think 15mm) glass. I'm not looking forward to drilling it and I'm extremely nervous about it because if I break the tank I'm pretty much SOL because my wife will freak.
Holy hell! I drilled a 3" hole through glass. It took over an hour and the bit was worn out when I was done.
