I did that with my 120 after having some substrate issues in the 90 (the clown car scape resulted in anaerobic substrate) and it worked really well to fill out the hills. It will also help hold the rocks in place as the AS is super light and just slips about under the rocks when I angle them steeply.
I love those rocks. Yeah, to me powersand is overprice. All of my scape with high hills/mountain use lava rocks and so far have been perfectly fine. Yup, they will hold pretty good. Can't wait to see more pictures.
