Reagent shelf life?

I am about to start the conversion process to BBB and after buying a test kit from Walmart that doesn't test FC or CC I came home and finally found my Taylor K-2006 kit from 2 summers ago.

I know I have to replace the reagents for testing chlorine but do I need to replace ALL of the reagents? Is there any of them that have a shelf life of more than one season? The kit was stored inside in a closet.

Thanks!

Here's Ben's Take on the subject

Thanks so much! Just what I was looking for. :)

Looks like I should only have to replace a few of them instead of ALL of them!
