For some reason my phosphates level (according to test by Leslie's) has been high over the past 9 months. (readings: 5/28/23 - 5 ppb, 7/23/23 - 241 ppb, 10/2/23 - 663 ppb, 1/18/24 - 530 ppb). They sold me Leslie's NoPHOS to use. Before I used it, I decided to have my pool replastered with Pebble Tech plaster. I thought draining the pool for this project would take care of the high phosphates problem. 5 weeks later after the pool was refilled on 3/22/24, I took a water sample back to Leslie's for testing. Results: 4/26/24 - 1676 ppb. WTF!
Can someone tell me what is going on? There is very little plant life, trees, etc. around my pool or in neighbors' yards. No leaves or fertilizer going in the pool water. Cannot understand where the source is coming from. There has been an unusual amount of rain this winter. Leslie's told me that rain can greatly increase phosphates. Is it possible that the pebble tech plaster has created high phosphates readings? Any thoughts or recommendations are greatly appreciated.
If your suggestion is to treat the water with a phosphates remover, what product do you recommend?
