Drilling and glass thickness?
 

I was talking to J&L today about having a 90gal (48x18x24) drilled for an overflow. They kept mentioning that they'd replace whichever pane of glass that's being drilled with a thicker pane. So if I wanted a hole drilled in the back, they'd replace the whole back pane of glass with a thicker piece. Is this necessary if all I need is a single 1" hole drilled in the back upper corner of a 90gal tank? In theory, shouldn't it just cost like $20-$30 extra to buy a tank with a hole in the back, instead of the $100+ increase they quoted me? Thanks in advance.

Mason,

as soon as you drill your tank it does weaken the pane of glass. Having a thicker piece put in is a good idea. I did it on my tanks. All of them. Piece of mind. You don't have to but....

Just take your tank to Crystal Glass in Burnaby, they did my 50G tank for only $10, the hole size was 1 and 5/8", the guys there were very confident about drilling tanks, the hole turned out to be perfect too. :D

FYI Seastar wants an arm and a leg for a drilled tank. as well as the markup added by J & L.

If your glass is 3/8 or thicker you do not need to worry about it breaking, if the person drilling the hole knows what they are doing. Just keep it at least 2 inches from the edges.
