Aqua green pool

[Watermom]

Good general guidelines for levels for vinyl pools: TA 80-120 but those aren't set in stone and you are fine at 140. You don't need calcium but it isn't a problem unless you get too high like maybe over 400ppm. Then you may have cloudy water issues. And, pH is ok anywhere between 7.2- 7.8. Your CYA is kinda high at 90 so I would advise not using any forms of stabilized chlorine meaning no trichlor pucks and no dichlor shock powder.
