Best Place to Drill 40 Breeder for RR?

Well I am about to start a new project. I just brought a brand new 40 gallon breeder All Glass brand tank from Petco. I am going to set it up first for QT to rebuild my fish populaiton, and later to try and grow out some of the fry that my false percs have been producing. I want to make it Reef Ready by adding an overflow. I was thinking of just doing the usual corner over flow with just one drain hole drilled through the bottom and then having the return over the top. This is assuming that I can drill the bottom. Does anyone know if All Glass tanks bottoms are tempered? I thought I read once that if you go very slow and have a good glass drill bit you can still drill tempered glass? If not the bottom I assume some place on the back. Should I create a small center overflow high up, still go with the corner or mabye a long overflow across half the back. Do I drill it high up or down low?

What do you think?

Thanks in advance,

Check with bdare, he drilled his 40 on the bottom. He checked with the maker and found out that the 40 breeder is the only tank that uses regular glass on the bottom. The only problem I see with the over the edge return is they can be a problem if you need to put a screen or cover on the tank.
 
Well I took a look at bdare's thread over on nano reef and I see he did;

A center overflow through the bottom with the return through a SCWD over the top

A feed for the closed loop through the back with the returns via an om squirt over the top.

I was not thinking about a closed loop but I do agree that the over the top return does cause issue with sealing the top. That is something I will have to think about.

The tank is an All Glass 40 Breeder and based on all of this link;

I am confident that the bottom is not tempered.

So now all I have to decide is if I want it in the corner or center.

Anybody have an opinion either way?
 
I would drill three holes in the middle and put up a black acrylic wall about 8"x3". Two of the holes would be drains and one would be the return tee'd into two locline tubes.
 
Hmmm, I can see why three holes might be good but since this will eventually be a tank for raising fry I guess I thought I would not want a ton of turnover via the sump. I do like the idea of two drains just for redundency. Oh well, more to think about.
 
You can always build a refigium section into the sump and have it fed from a T line on on one of the drain lines. That way you could control the flow into it. I will always have two drain lines when ever running a sump.
