I want to make a vertical LR "wall" for the side of my new cube tank. How can I attach LR together? Basically, I would like to use my flat rocks and just construct a wall, about 18 inches tall by about 6 inches wide and as thin as possible. I've considered connecting them wiht cement, but don't really want to wait 12 weeks for it to cure. Any brilliant ideas out there?
