does Seachem Prime expire?

[montanafish gal]

Hi all!

I found a bottle of Prime that is anywhere from 5-7 years old, I think. Does anyone know for sure if it's any good? Would hate to throw it away if I can still use it!
Thanks!

I don't know. I do know that my last bottle started smelling less prime like, and I thought it was becoming less effective towards the bottom of the bottle. I opened a new bottle and it smelled really strong.

If you contact Seachem, they will say it has no expiration date.

I would be surprise if it expires and become ineffective.
