Well, you can, but it's not always necessary...factors such as tank depth (ft. to back) and height of the rockwork, will affect stability. But, besides that, you can drill rocks, and put in PVC or acrylic rods, for support. If you're planning on keeping corals that need room to grow, you may not want to pile rock up too high.do you guys use any kind of glue or something like that?
