I have a bottle of Cycle that I bought I would say at least 2 years ago. It's never been opened would it still be ok to use?
 
I don't know, does it have an expiration date? The question is, why do you feel the need to use it?
 
It says 7/03 on the bottom of the box. Don't know if thats expiration or manufacturing date. I have recently just gotten back into saltwater and I went to put my new calcium test kit on my fish shelf when I noticed there are a lot of things on there that are really old that should probably be thrown away. I just didn't know if this was one of them or not.
