Well, it's been awhile..but I do have something to add here about leaving ProZinc on the counter after dosing!
I left mine out the very FIRST time I used it, for 5 hrs!!

I was panic stricken and so embarrassed, I couldn't even tell anyone I did it!!
I worried for the next week, or more


But I never noticed a difference at all!
I even did it AGAIN. 2 HRS or less, but still..!
I am nearing the expiration date now, and while it may be losing a bit of to-be-expected potency..I've never seen floaters at all.
Thanks
