In another post i was talking about how i am having to completly restart my tank b/c of hurricane Katrina. Well I have the rock re-curing in a rubbermaid container. I look today and several of the pieces have a grey film forming over the rock. It can be rubbed away like cyano, but im not sure what it is. Sorry i cant get a pic. :help:

I found this same problem in a little 5G I just started. It has two pieces of rock in it right now but thats it....and lots of grey dust everywhere....!
