Return hole size.

I'm looking at drilling the back of my tank for my return. Just curious what size is standard or what people use when drilling the glass. Thanks!

How big is the tank is my first question :-)

It's a 50 breeder. It has a corner overflow with a 1 3/4 drain and a 1 1/2 return. But I Wana do the herby style overflow and use the 1 1/2 for full syphon and the 1 3/4 for the backup. Then that means I'd have tk drill the back glass as long as it is not temporal (wich I don't think it is).

Tempered

If the normal drain is 1.5 then the return should be 1, most is 1.25. Just my opinion ; -)


I thought only the bottom panel of the tanks would be done with tempered glass. Anyway there is an easy way to check right?

Well the bottom glass isn't tempered because it is drilled.

Not necessarily :-)

O, didn't know it could be drilled at tempered. But still don't think the back glass is tempered though I'll test it to double check though.

The new DC pumps have large intake and discharge so you might consider a 1.5". They provide so much flow you might not even need power heads.

I remember there was a discussion on rc about this tempered glass. Just because the panel has a hole, it does not mean the glass is not tempered. Also, there was a discussion about how to drill tempered glass....
