Vinyl liner pool, 37,500 gallons. Used citric acid, about 18 lbs, to get rid of stains. did the trick day one, but on day 3, pool cloudy. day 5, went to leslies pool and they said ph low. added 10 lbs, went back 4 hours later, still low, another 4 lbs would do the trick. told me to use my setting of 2 on the heyward chlorinator when i usually use 3. still cloudy today. instead of 3 lbs of shock, i used 1.5 lbs. water looks green all over, i think that is just the chlorine.
so, will it burn off and everything right after that? take it back to leslies to test tomorrow evening?
suggestions>?
