Why is there a pink or black ring in my toilet?
Bacteria, fungus and mold spores normally found in the air can cause rings in your toilet bowl. Wet surfaces provide ideal conditions, and the organisms reproduce rapidly, growing together to form a ring. The color of the ring depends on the species of bacteria, mold or fungus.

You can easily remove the rings with a toilet bowl brush and household cleaners. Close the toilet lid to reduce the number of spores and reduce the light needed for growth.
