What is in our tap water that causes a pink film?

A pink or black film on fixtures may be caused by an airborne fungus called Aspergillus sp. that is commonly found in bathrooms and kitchens. The fungus reproduces by spreading spores via air that land on moist surfaces, which are ideal conditions for its growth. A cleaning solution of one part bleach to five parts water, or commercial products containing bleach are effective to kill the fungus and remove most stains.
