I have 25K gallon vinyl pool and have been taking care of it for over 20 years. Lately with all of the rain, I had a PH of 6.5 and Alkalinity of 40. I usually use Baking Soda but decided to use Soda Ash instead because it was more convenient. I added 8 lbs premixed into the deep end right above the main drain. I instantly saw a white fog engulf the pool. It has taken a couple of days to clear up but has left white sediment on the bottom which I am brushing up. I have been through the forums looking at other people who have posted and no one has really explained why it turns the pool cloudy. Can anyone explain the chemistry as to what made my nice clear pool into a white fog and is it normal?
Thanks so much
