Suddenly could not keep chlorine in the pool. Started SLAM yesterday with the following readings:
Added bleach and brought FC to 26 at 7p yesterday. Turned off SWG and ran pool overnight. At 6am had the following:
FC 27 (margin for error)
Water is clear.
Good right? Next test at 6p today. FC = 10. What's up with this? Ok, it was partly cloudy and 95 deg. But, is it possible to lose so much so quick?
Do I need to raise it back up again and try again tonight?
