Hey guys, I got a 15' by 48" pool for free last summer, got it set up, and now I'm just starting learning about PH, Total Alkalinity, Chlorine, and pool chemistry..... The pool came with two small testing kits for Chlorine, PH, and TA.

How long the kits last depends partly on how they're stored--heat being the main thing that will ruin them. If they use Taylor reagents, Taylor says its stuff is good for a year and I read about people using the same stuff for two years with no problem.
