Sorry if this has been answered several times already. I tried a search, but couldn't seem to find the right search terms to find an answer.
What is the expected shelf life of a TF-100 kit? I live in a northern climate, and we can only use the pool in the summer months. Can a kit purchased now still be used next year? Or is it better to purchase a new test kit when opening the pool next Spring?
Thanks in advance for replies.
