Good afternoon everyone! I have a TF-100 that I bought last year (worked great, thanks for the recommendations). I am about a week or so from opening our pool...I wait until the oaks and cotton woods stop blooming!
Question is do these chemicals in the test kit loose their potency or am I good to continue to use this from last year?
Thanks in advance!
