There is a “pink slime” in my shower. Is it from the water?
No, certain species of airborne bacteria gravitate towards and thrive in a moist environment, such as showers, toilet bowls, sink drains, tiles and dog dishes. These bacteria are naturally occurring and unattractive, but are generally harmless. The best way to avoid this problem is to keep the surfaces free from bacterial film through regular cleaning using Lysol or a chlorine-based product.
