We have been living in Miami for over twenty years --more humid than the villages. While mold is an issue in Florida, the orange stuff is not mold, but minerals. Sounds as though there are two issues with the water in TV. The discoloration and calcification from minerals and tge taste of bleach from the chlorinization of the water to make it potable --so I guess that means we will need both a water softener to address the minerals and a filter to address the taste --or is there a one-size-fits-all?
