After about 3-4 days , the water in the toilet has a pinkish ring to it.?

Question

I know hard water stains the toilet and we have a water softener, but is has never neen pink before, does any one know the mineral this is?

Answer 1

Pink growth on bathroom fixtures
The pink growth or stain is the result of a mold or a bacterium, specifically, Serratia marcescens. The mold is present in the air. Mold and bacteria grow wherever there is a warm, moist or humid environment, like a tub or showerhead. The mold and bacteria feed on the small quantities of nutrients in water.

Regular cleaning with bleach or a cleaner that removes mildew will clear the mold. Wipe away standing water to reduce growth. Certain materials, like rubber, plastic gaskets, etc., contain nutrients that help these organisms grow.

Answer 2

It's more than likely the by-products of the bacteria living in the toilet. After one uses the toilet, and flushes of course, there are still some bacteria left behind from one's feces --they naturally live in the intestinal tract. The pinkish ring you see is more than likely waste from the bacteria in the water that has settled around the toilet bowl. A good toilet cleanser should knock this ring right out.

I hope this has helped!

Answer 3

Likely, it is not a mineral, but algae. The standing water, combined with, well, the use of the toilet, creates a perfect breeding ground for such activiy.

Answer 4

It sounds like rust.
