back to my staining problem. I have had the water checked for metals and have tried different removers. I don’t add water very often. When I open my pool for the season its fine for the first few days, then the staining starts and its a problem all season long.


Does the 1st staining happen to coincide with the addition of sanitizer (chlorine), say within 24 hours? If so, it could be starting the staining. That could also indicate a problem with a metal that is not tested by the pool stores such as magnesium or silver.
