Hi all, we just had our pool refinished with sunstone quartz, after a few weeks we had a lot of dark staining, the company came back to look at it and suggested adding 5 gallons of muratic acid every week for 3 weeks and continue brushing, after doing this it was better but we continued to add 3 gallons a week for a further 3 weeks and still brushing daily, it looks fine now but I'm noticing white clouding while brushing and the surface feels rough and loose to touch, also the chemistry is way off, does anyone know if this could be damaging the new surface? Or any suggestions on what to do next? Thanks
