45 seconds in fw is enough to kill montiporas. Acros won't be happy either.

If you want to slime your corals, just expose them to air for a minute or so. Some people do that for "air acclimation" before putting corals into their tanks. The slime moderates salinity and chemistry differences as it slowly clears away.
I don't bother acclimating either. I quit doing that years ago after finding out that LFS and wholesalers don't bother, as Gresham said.
[quote author=MontanaBay link=topic=4320.msg52454#msg52454 date=1218768894]I didn't know that about providone being slower acting than Lugol's, good to know.[/quote]
Povidone Iodine isn't slower acting than Lugol's Iodine, but the article may not have been perfectly clear on that.
The implication was that iodine in general is slower acting compared to other disinfectants, like bleach for example.
