A few years ago I had a total system loss. I never emptied my tank so my live rock was just sitting there. 99.5% of the coralline algae has died as well as everything else. There are a few spots where there is some purple, mostly where the sunlight hit the tank through the window. This weekend I purchased a new lighting system and did a water change. Got the pumps running again. Any chance anything survived? Should I get a new piece of live rock to kick start the tank again? Any suggestions would be appreciated.
