If the masonry was strong enough to hold the water the last time you did this, then just set the back glass in -the entire width- then set the two sides in against that, then set the front over the edges of the sides with silicone in the seams. That'll all be locked in when the tank is empty, as long as your method of mounting the front works well. When the tank is full, water pressure will hold everything up, so I really don't think you need to be that generous with the silicone, except in the seam where the front sits against the two side edges, and maybe some dabs at the back of the sides to keep them from slipping inward. I'm assuming your last project(s) had glass in the front and you were able to mount it effectively and avoid blowouts.
