I just put the glass where I wanted it and put a bead on each side to form a
gusset and lock it in place. For the center of the bubble trap I cut 2
short 1/2" lengths of 3/4" pvc and laid them on the floor and set the center
glass on them to keep the height.

Did the same with acrylic in the return area as I had to drill holes in it
and bend it. There is no pressure differential on either side of the glass
to speak of so the silicon is jus there to keep it from falling over.

Glass on glass will work 100% better than acrylic on glass.. Go for
the glass and 100% pure silicone ( I like the DAP brand)

Great. Thanks guys, I'll go with glass. One (dumb) question then. When
using the silicone, do I put it BETWEEN the glass pieces when joining it,
or do I put glass on glass, and then line the joint on both sides (like
caulk)?

Thanks
