I have a TF100 test kit obtained just last year. I got it well into the swim season and then adverse weather further limited pool use so I didn't stay on top of it nearly as much. As a result, I haven't used that much of most of the chemicals.
Are those test chemicals still good and if so, how long will they be? On that note, what is the standard use rate for a normal season? Will one season generally use up a kit's standard supply?
