What is that black ring in my toilet bowl?

The black ring is caused by an airborne fungus. The spores land wherever it is damp and can also be found around the ends of faucets, around leaky faucet handles, and showers. We recommend 3 applications of straight bleach to help kill the spores and leaving the lid to the toilet down.
