Does Prime have a shelf life or expire?

According to Seachem Technical Support "Prime is formulated to have a practical unlimited shelf life (i.e. practical within expected usage time frames, for example it's not likely someone would try to use a 20 year old bottle of Prime)."

I hope this helps.

Thanks.
I have a bottle that is about 2 years old and was just wondering if it was still OK.
