I'm sure the larger Jebaos can work on 3/4th inch glass. They have a small suction cup on them too which would probably do a lot of the work on keeping them on your glass - once you attach it with the magnet there is some small suction force that keeps the wavemaker on the glass.
I didn't see that they have glass thickness ratings though.
I have skimz SS18.0's on my 650g FOWLR with sharks, which has 3/4" glass. They stay put just fine until one of my sharks decides to knock it out of alignment. Doesn't fall off though. They're great if you need to push water a long way in particular.
Also have a Gyre. Great water movement and no issue on the glass, but mine is a bit unreliable (XF150- bought used)
