I have been reading and looking at tank set-ups all over the net, trying to steal ideas. Anyway, I read somewhere that if you going to do any drilling to use use some kind of rods to support your LR, and even if your not, that you should pre-drill some holes in your LR 3/8 in. thick,to place corals frags in at a later date, in places you like. My question: is that the way coral frags come, I sure would hate to drill 5 or 6 holes in my LR and then the coral frags come in differant sizes than 3/8 in.? If any of you have any suggestions that might help me in this aquascaping thing, feel free to give them to me. There aren't to many artistic bones in my body. I am leaning towards some kinda layering thing, kinda like diff. levels to the strucatures.
