Just a quick update, I continued diluting/exchanging the water for another 48 hours. On Sunday I fired everything back up and thank God my CC's were 0 and FC was about 8 with my CYA at 40! I was able to get the pool balanced and had the family swimming for Memorial Day. Thanks everyone for all your help here. On a positive note through all this, the initial acid treatment kit did work very well. All my calcium scaling is completely gone. But I don't think I would do it again.
