So im getting a used 55 gal tank, I would like to have holes drilled for a overflow and return, How do I tell if my tank can be drilled? if it has a temperedglass sticker on bottom, is that just the bottom that is tempered? or is there another way to tell? also if i want a 1 1/4" overflow what size hole needs to be drilled for this? same for a 3/4" return?

I want to do a jet/spray bar under my sand with heads popping up that can pivot to be positioned at deadspots, anyone do this? Ive tryed and couldnt find the 1 picture that I seen of someones setup.

also should i use 3/4" or 1/2" for the jet/spray bar?

Chances are you won't be able to drill the bottom since that will be the piece that is tempered. Not sure what size holes you'll have to drill for those bulkhead but you should be able to google search them. Return size will depend on your pump.

I just want to have 4 holes drilled in back of tank, a bigger 1 on bottom of each outside corner, and then 2 holes towards top for the returns. typically is the bottom only piece that is tempered?

Typically, only the bottom piece is the one that is tempered.
You can do the drilling yourself. The diamond tipped drill bits are readily available on ebay & are fairly inexpensive. Just be sure to use plenty of water to keep the bit cool when drilling & let the drill bit do the work - don't force it.

It was probably my tank here is a link to the pictures

Although my setup is all contained inside the tank with pumps on the back wall behind the rock.

I used 3/4 line and have great flow coming through. I figured the bigger the line the better I also put valves just after the pumps so I could restrict the flow if I wanted too (though I have not wanted to as of yet).

I also used loc line for the pivot heads here is a link to a place that sells everything you need if you want to use loc line.
