My pool is open just over a week now and the water is crystal clear!! It look beautiful … however - it doesn't see I am holding onto any chlorine? Where is it going? I have shocked with 2 gallons of liquid chlorine four times (at least) …. last tuesday, thursday, sunday, and again yesterday .. I may have even shocked once more in there. I opened last Tuesday and pulled out the filters and CLEANED them on Sunday. My SWG is on at 100%. I am actually still floating 4 3" chlorine tabs …. and just tested again (just with a test strip) and there is NO CHLORINE.
Last water analysis (yesterday before shock)
Phosphates 100 (i did phosFREE on Sunday)
