Hello,
I've been getting this discoloration at the bottom of my toilet. It
looks like something is peeling off the bottom, but not sure what it
is? Anyone know? Also, is there a chemical product that i can use to
get rid of this? Pic below. Thanks.

Calcium buildup. If it is a light case a product like clr might remove it.

For a heavy layer reduce the water level to the lowest point and use about a
quart of muriatic acid with the window open. The fumes are nasty.

Be very careful if you use the acid!!!!!!!!!!!!!!!
