I tested my CYA today and my TFP test kit says I have no CYA. this is strange because I tested it a couple of times in the past 6 months or so and it said it was at like 40-60. I have had a lot of rain, but I don't drain the pool, I just let it evaporate so I don't screw up my cya and salt levels.
So my question is, can CYA just evaporate? Either the chemicals in my kit just went bad or I really have lost all CYA. I've been having problems with my salt generator producing some chlorine in the morning and then I test in the afternoon and the level is zero so its all pointing towards the stabilizer.
