Thanks guys, the tank is just happy right now. At some point I'll screw something up and my least favorite colors of brown and white will return. On a side note, I was at fengs today and all I can say is that man has built the biggest tank I've ever seen!! Wonderful time chatting and seeing all his home made tanks. The corals are outstanding in color and size. One can appreciate what A true colony looks like. Gotta go back.
