Just got an Aquarite 40K SWG from craigslist and have a 24K, vinyl pool. In testing, we have 0 FC, high CC greater than 3, PH 7.4, TA 50, Calcium 170, and 0 sanitizer. Bought the house and pool had been neglected. Question is do we shock first and get pool specs to recommended levels before installing SWG? OR install SWG first and then shock pool?
Also, will shocking with bleach get us back to recommended levels for FC? We added 5 96oz. jugs of 6% and only got up to just over 1 FC and high CC's.
