My live rock isn't very porous and thus doesn't have a lot of holes for frag plugs. I would like to add some frags, but not sure how to attach them to my rock work.
Do people take out the rocks and drill holes in the rocks to hold the plugs? Or is there another way?
Any suggestions are greatly appreciated.
