Thanks for the previous help. I have opened our pool, running the pump since this morning. Test results as followed:
My question: once I started sweeping the pool, it turned cloudy and the FC started dropping from 25 to 23, CC increased from 0 to 2, pH dropped from 7.8 to 7.2. I know to keep pool at shock level until the overnight test shows no drop in FC levels, but since FC is so high to begin with, should I just continue to brush, sweep and retest in the morning? Also, is it best to bring up the pH and TA now or wait till the FC comes down? Am I correct that shock level is 16 for CYA at 50 in a nonSWG pool, 13,200 gallon vinyl AG?
Thank you again for this great resource.
