What to do???

[stevearthur]

I just called the manufacture about my free 28 gallon bow front tank(TopFin) and I found out that it is tempered glass. Should I just go our and buy a new tank or should I just do a overflow with a syphion? I had planned on adding bulkheads but from what I have heard, you can't drill tempered glass. I really don't want to buy a new tank because I bought my lighting for a tank length of 24" and that means I would have to drop down to a 20H tank. Any suggestions! I am planning to stop buy the LFS to ask for advice on my way back home from teaching.

Darn it!!

No, you cannot drill tempered glass. It's pressure treated and any drilling, chipping will shatter them into pieces. Call them again, and ask if they can modify it and put a internal overflow box into the tank? Sometimes tanks are made with tempered glass on the 4 sides, but not the bottom plate. If the bottom plate can be drilled, then you will just have to glue a top-slotted internal overflow box around the plumbing.

Otherwise, the last resort is the hangon overflow.

no, the whole dam thing is tempered. I will have to do a siphon skimmer/overflow. I am also planning on two maxi-jet 900's on a wavemaker. All this with a 20 gallon fuge down below.

FWIW, AGA makes a 26 gallon bowfront that is also 24" long. Not sure, but I think only the bottom of the AGA is tempered so it could probably be drilled in the back. You could contact them to confirm.
