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 from the water supply (hardness).

Muriatic acid is very effective in dissolving
the minerals.

Muriatic acid is also VERY dangerous to use!!
Wear eye protection and have good ventilation.
Rubber gloves to protect skin.

Plunge the bowl to get rid of as much water as you can.

GOOGLE "muriatic acid" so you know what you're dealing with.
