im waiting for my chlorine to get down to 0. (at 1.5 right now) and i will be doing the absorbic acid treatment. i have a question as well. right now my PH is at 7.0... (AlK normal). is this an ok ph to do the treatment. im using natural chemistry products. Stain-Free and Metal-Free. the Stain-Free says to have Ph btwn 7.2 and 7.6. i dont want to raise the ph just for it to drop and have to raise it again.
