Thanks Goodwin9, Actually, I took those pics today, but actualy the tank isnt looking as good as it normally does. I changed 2 of my six metal halides fro 20000k to 10000k and now I have a cyanobacteria issue under those lamps. Its like a big red stripe down the middle of the tank. It hasnt affected my corals at all, but its a sign of dropping water quality in my opinion. I checked my ro/di unit, and my filters are all exausted, so my top off water has been high in nutrients. I got new filters yesterday, should be back to normal in a few days. However, like I said, it doesnt seem to be affecting my livestock.
