Hmm, does anyone know anything about metal allergies? I wear a sterling ring on that finger and I'm wondering if maybe I'm developing an allergy to silver, nickel, or copper. I've worn the ring on that finger for years, but only been dealing with saltwater on a daily basis for the past 4 or 5 months. So I wonder if the saltwater is reacting to the alloy and causing the reaction - maybe it needed to build up over time and the large amount of contact from rearranging the tank this weekend finally triggered the reaction enough to notice. So it turns out that the other 7.5% of sterling is usually copper! Is it possible that the saltwater is reacting with the copper or other metals in these short amounts of time that I'm reefing to be affecting me or my tank's parameters? I'd be especially interested to hear of other accounts of metal rings causing circulation problems.
