Yikes, Bev! Glad it all worked out - I've heard a couple of horror stories on RC of doctors stamping their feet and insisting it can't be the fish tank until things got really ugly. I think our local breed doesn't want to admit they don't know anything about tropical diseases..
Anybody else find they get a reaction on their skin when working in the tank? It never seems to fail that when I'm doing a water change and in the tank for more than a minute or two, I get a nasty rash on the underside of the forearm and it always takes a week or so to go away. I'm never brushing against corals there or scraping the sides so I can only assume it's something nasty floating around in the water.
