acropora1981 Posted December 11, 2009 Share Posted December 11, 2009 I have a bunch of frags on frag plugs, made of...well ...concrete? I guess...aragonite...who knows, they're like these Frag plugs. Anyway, right now I just have them crammed into holes in the rock, but a lot of them keep falling out. What I'm wondering is, can I drill similar sized holes in the live rock to make secure places, and if so, what kind of drill bit should I use? Any handy tips/techniques? Link to comment
