I have a couple of questions.
I am going to shock my pool for the first time (the real way with liquid and not powdered "shock").
My CYA is 100 so. Know I need LOTS of chlorine per the calculator.
1. Is it better to do a partial drain first (few inches so I can water my lawn. In so cal drought)
2. If I water my lawn, what is an OK chlorine level to not harm vegetation?
3. How soon can we swim after the shock?
