12% liquid chlorine in his pool at one time...is this ok? He has an inground gunite 35000 gallons. I took my tf100 over there yesterday and his CYA was at 100....FC was 0
His water is cloudy and this is why the pool store told him to dump 56 gallons in at one time....I mean, I have probably used close to that amount trying to get rid of Algae but not at on once...maybe over 2 weeks! The pool guy told him everything would be good by Tuesday... Talk about shocking your pool! Lol!!!! He is in the country and claims that he can not drain and fill his pool, if only 18 inches at a time bc his well water will stain the pool? So he plans on keeping his high CYA. Whatever.....I also saw some dark green stuff in the filter hole and he told me it was rust... Green rust?
