Gluing live rock to the back glass?


New member
I'm planning a 32 galleon tank and to give me more options in the aquascaping I intend to glue pieces of live rock to the rear glass.

I'm going to cut them with a saw or something similar to get a smooth surface to bond with, and I'm not going to use big heavy pieces, probably just try to make some "shelves" higher in the tank.

I'm not really sure which product I can use to mount them securely though. The tank is empty now and I can do the mounting "dry" before I fill it.

Any ideas or advice?
