FC 21ppm (was attempting to shock as water had very slight green tint upon opening 7 days ago)
pH 8.2 (or off the chart)
CYA well above 100
Pool water is currently crystal clear. My refill water tests @ CH 100. I am thinking of draining and refilling to get a better handle on CH and CYA levels. If drain/re-fill recommended, do I need to wait for the chlorine level to go down before draining to my lawn?
Thank you for your input,
