Just removed Loop-Lok cover last nite.
Usual dark green swamp!!!
This morning tests show high PH.
The test #'s
CYA: <20 (cloudy but can just see black dot)
1. Is high PH caused by the cold water temp?
2. Do I need to lower PH before starting to "Shock and Hold"?
2. I use liquid Chlorine to open and shock, pucks for maintenance, so CYA slowly climbs thru the season(May-Sept. 1st.)....so do i need to raise the CYA
before I start the "Shock and Hold"?
Thanks again for the awesome resource this website and to it's Mod's and members.
Have a Great Day,
