Steve, I had a thick black fungus growing all over the inside of my toilet when I came back from a week on vacation - it looked like black moss, sort of. Only happened that one time but it was one of those things that prompted me to get a full house water filter. My one neighbor described a thin black fungus that was causing creepy crawly sensations on his legs (he said it came off when he poured alcohol on his legs in the tub so he's convinced it was growing on his skin). |
