So I bought the TF-100 kit last year. I still have plenty of chemicals left.
I know i'll need some more DPD power and maybe some more CYA solution, but for the most part, i'm all set.
One question I have. I store this stuff in my garage. And it can dip down to around 45 degrees sometimes in there. Is it recommended to replace the chemicals each year? Or can I continue to use them until they are gone. I read a post a few months ago about this but I can't find it now. I know some have more shelf life than others.
I mainly do the FC, CC, Ph, and CYA tests. I did a full range of test twice last year and these 4 were the only ones that really changed.
Just trying to figure out what all I will need to restock this year. I know there is usually a sell on the chemicals around March sometime.
