My thoughts are mixed... one thing for sure is my neglect played a large part in it. My tank took a back seat to "life in general" and because of that I let an algae bloom become an algae Atomic Bomb! I let it go until the algae suffocated the live rock, coral and every surface in the tank. I can't help but believe that over-all poor water quality was the ultimate demise of the tank.
I've got brand new rock to put in the tank (it's currently rockless except for one "token" piece of rock) and only has a single Yellow-tail Damsel in the tank. I'm planning to completely clean it inside and out (moving it into our new house ) and start it back up from scratch.
