I am getting ready to open the pool.. I have filled it up to the correct level and am getting ready to take the cover off but did my water testing
CYA=20 I could still see the dot in the bottom even after it was full
First I was wondering if I could go ahead and shock it with the winter cover still on and how long do I need to keep it at shock level? How much shock should I add?
I am a little rusty as it's been a few months since I messed with the pool.... Thanks bunches....
