So I am in the process of removing my sand from my 180, was just going to leave the rocks on the bare glass. If I had to guess my rock work doesn't go up on both piles more then half the tank. Who here has larger tanks with the rock work on the glass? Some have told me to put Starboard down, but I dont plan to remove everything to silicone the gaps etc.

Rock directly on glass is fine, many do it with all sizes of tanks including myself. Just limit any sliding of the rocks to avoid unsightly scratches.

I have not put anything between the glass and my rocks on any bare bottom tank I had. Unless you drop a rock in air from above the tank you are not going to break the glass, in most cases.
