Do you all lean your rock aqainst the glass I try not to and it seems that I cant get my structure to look as good as some I've seen on here. Does it scratch the glass or put stress on the seals?
most people sat stacking LR agaisnt the glass is not that good, although one small piece(like at the very top) is not going to hurt.
try making a wide base and just work your way up, kinda like a triabgle if you look at it from the side.
