My pool located in Henderson, NV is one year old and started producing large visible white flakes over the last several months that float to the bottom of the pool. The 5000 gal pool is crystal clear with all water chemistries in spec. I believe the SWC is the culprit for the white flakes, since I observe the flakes enter from the water outlets in the pool. So, I clean the cell every month (4:1 water-MA) and have conducted my quarterly pool filter (cartridge) cleaning. Daily, I manually skim the pool bottom with a fine mesh screen and have collected about 2 oz of flakes over the past couple of months. I have noticed the main drain filter has about 10 grams of flakes, but the cartridge filters did not show any white flakes. The flakes breakdown easily when wet and tend to solidify when dry. I noticed the dried flakes will bubble with MA, so I think it has to be related to calcium. So, does anyone know how to fix this problem. Cant replace water, since the incoming local city water is the calcium level. Is there a way to reduce the soluble calcium level in a pool? Or is there something else I should investigate???
