So, I went to the pool store and took a water sample to see how it aligns to mine and I left the store with something I probably didn't need and is now causing me grief! She tested my phosphates and said they were high. I added 9 oz as prescribed. 48 hours later I vacuumed to waste and back washed 3 times as she said. This was a week ago. I still have cloudy water (which I didn't have when I went to the store) and the walls of my fiberglass pool are chalky. I use a SWG.
Can you help!! Thank you!!
