This is the tank all bare and empty. Due to a fish mishap and the fact that it was run as a marine tank for the last year or so, I filled the tank with water and bleach and let it stand like that for a week, filter and lights running only. I have changed water twice to start diluting the bleach and the next step will be draining the tank and filter and adding a heavy dose of dechlorinator and then setting the tank up.
