Thanks Norman, started scrubbing it down last night, gotta buy a gallon of vinegar today! I think that some time cleaning it, and maybe a polishing kit, and it will look great again.
You bagged up that cactus coral, and I walked away with out it. I came back by a little bit later and didn't see it, but I'm not 100% sure where you might have set it down as we were moving things around. I hope someone got it and it made it's way into a tank. Sorry about that.
