I cleaned it up one rock at a time. Lifted each out of the tank and scrubbed (and scrubbed). I dropped most of the rocks I cleaned in a weak (2%-5% bleach solution).
It took a long time.
There's fewer rocks now. And it looks a bit different. I filled a 2L ice cream container with rocks that weren't put back. Still need to put the sideways rock back somehow. But so far so good, it's looking nice tonight.
