just moved into my first rural property which is on well and septic. Today I noticed that the upstairs toilet had a weird flat object lying in the bowl that seemed to have come loose from flushing. I fished it out:
Can anyone tell me what this is and if I should be concerned? I would guess some kind of mineral build up because our well water is very hard. It's brittle and breaks apart easily.
Also, not sure if related but I've noticed that toilet in particular has lots of bubbles "fizzing" in the bowl, particularly after flushing, which I haven't seen before and it doesn't happen in the other bathrooms in the house.
Any insight appreciated, thanks all!
Edit: attaching a photo of where it was. Just lurking, almost out of sight. Toilet appears to be ceramic as far as I can tell.
Also, I noticed taking this picture that I am able to scratch away at the brown stuff starting to accumulate on the bottom maybe the previous home owner was just not very diligent about cleaning...
