I just purchased about 100# of live rock for my new 140 Gal tank I am setting up. One piece is about 18" across and would be a beautiful shelf however I am not sure how to attach it top the other rocks so it will not collapse, do I use Epoxy or cement or something else. I appreciate any suggestions.
