With a little, A LOT of help from Jesus, not Heyzus. I managed to successfully drill a 1/2" return and 3/4" drain in rear compartment. Remove one of the baffles so not to create or leave the so-called "chamber of death". Then drill another 1/2" hole above the factor returns to raise/maintain a higher water level when power is down or return pump is shut off to control draining from display.
Interesting thing I use to do this almost daily without thinking. And of all places a company I first learned the trade, "Marine Glass" which is now long gone. Done it at many other shops as well. Still can't remember if I ever lost a sheet of glass/mirror. Never worried when doing it. Maybe because it wasn't my money nor was I doing it freehand. Used a portable press and just let the weight of the drill do the work. Also had access to quality bits made by reputable glass companies. No EBay 30 years ago.
So, as far as I know, I own the only 130 drilled through the bottom. Seen the back drilled but not the bottom. Been searching for a cheap/free acrylic tank to butcher into a sump to fit underneath. Seen an ATO tank that would work great but I'm a cheapo and they want $60. $60 seems like a lot to me to but something to cut in half and glue back together. But it would create instant baffles for me and fit perfectly. But only 10" tall. Pondered a larger fuge/sump to sit next to it.
