I had my water tested at Leslie’s pool store and they told me I needed to add 11 oz of soda ash and then 5 oz shock. I have a 1,000 gallon Intex pool. I dissolved the soda ash in water as best I could before adding it to the pool. After the cloudiness cleared, the next day, I noticed white deposits all over the bottom of the pool. I tried stirring it up, but it just keeps settling to the bottom. It’s been 2 days now and I’ve stirred it up multiple times, but it won’t dissolve.
