My 3 year old viking pool has developed a bad white "haze" on almost all surfaces below the water line. I have tried everything to remove it before I open the pool. Tried, vitamin c, 50/50 bleach, 20% muratic acid in a spray bottle. The only thing that will remove the stain is 3M heavy cut rubbing compound and a ton of elbow grease. I travel a lot and did a terrible job last year of balancing the water. I'm sure that has something to do with it. The pool is very small, 5500 gallons, 10x20, "small unicorn" model. I normally drain and refill each year (sandy soil, so no worries with draining). Any ideas how to remove the white staining without 2 days with the power buffer?
