I need about another 6 or 7 pounds of live rock but I want to add some hard corals in there. I have three different zoos, various mushrooms and ricordia's. I don't really know yet. I want to have a variaty of color but I still want my rock to show. I don't want it completley covered up because some of my rock is awesome. I guess i want it full but not packed. I'm going to slowly build up...I found this lady in IL who has about 800 corals in her basement that she sells for dirt cheap but it's a two hour drive so i will slowly build up. Actually i'm thinking about converting my 75 gallon over to a reef tank because her stuff is so cheap.
