im sure there are a few of us in Texas who survived the freeze and are getting pools back up. My testing chemicals where outside and below 20F for about a couple of days.
1. Are they still good for testing or do they need replacing?
2. in October my CYA was 60. when I test now I can still see the dot when the tube is full so CYA is really low. Where did the CYA go or do I need new chem.
