Does Salifert Iodine expire?

Anybody know how long the stuff lasts? Thanks!

Pretty sure all test kits do. should have a date on it

Thanks, but Im not talking about a test kit. Im talking about the actual Iodine supplement...

Any input on that?

If it doesn't have a date anywhere on it and it doesn't look separated you should be okay, but I tend to not like risking that sort of thing. I would rather pay $15 for piece of mind the risk it being bad.

Iodide may eventually oxidize to iodate. Both are naturally occurring in seawater, and iodate predominates anyway. Some kits may not detect it properly.

That said, I don't think iodide or iodate is a useful supplement for most folks.

Thank you both for the help. I just went ahead and threw it away. Dont really need it anyway. Thanks again.
