Opened the pool , it was a green mess .Vacumed algae out , slowly clearing up . The Cya level was 0 !,and I had 2 pm of Ammonia (yes, my yearly problem) I shocked the pool with granules and put the SWG on Boost .Ammonia is gone and I added CYA Sunday evening, it is now up to 50 ppm .Fc is 11, I figured I'll leave it high until I'm at my 75ppm of CYA , still a little cloudy but I'm starting being able to see the bottom. My Alk is 90, Ph was 6.8 , I guess after adding the Cya the Ph dropped ?? How can i clear this up quickly and how long do I wait before adding more Cya ???
