Unfortunately let my FC get down to 1 and a algae brown green dust followed fast! Shocked the pool and got it back to crystal clear again. My SWG is at 40% and I was wondering if I should keep it that high or lower it. We are using the pool daily at present. 20 hours after shock my PH is 7.5, FC at 12, CC 0 TA 70 and CYA at about 55. What % should I adjust my swg to and when is it safe to take a dip??
