The bottom of my pool has a white patchy look to it. The pool is painted a dark blue so the white patches show up very well. When I brush the bottom a cloud erupts but the white patches do not go away. No amount of vacuuming will remove the white patches. the pool is plaster/gunite bottom with fiberglass sides.
I use a Mineralize Model 401 by Lifeguard Systems for my purification keeping a copper level at .2 to .3. PH, Total Alkalinity and Calcium Hardness are all balanced where they should be. The water is crystal clear.
Anyone have any idea what the white patches are and how to get rid of them.
Thanks for any help
