Another thing to add to this discussion is ways/ideas to not only test spots but get different growth patters is hanging frags. You can string frag plugs and corals with monofilament and hang them from a rod across the top of the tank so they are suspended in the tank this allows you to test spots, growth patterns,keeps CUC from knocking over your frags not to mention it looks cool. If you have never seen this done it's worth searching on the internet.
