Please advice me on Aquascaping a Bare bottom Tank

[nature786]

Hello Everyone,
I'm settting up a 120 and moving everything from my 90 but this time I don't want to add sand.
What are some tips for making sure my rock structure is stable and to make sure they don't slide on the glass.

Thank You all.

I would try to put something on the bottom. I didn’t and am terrified I will crack my glass. I believe there is a product called starboard, but I’m not sure of the name and you’ll have to search that one. I did use acrylic rods to secure my rocks and glad I did that. Good luck.
