First off, first real year using TFP and my pool is gorgeous. Thank you very much TFP for making owning a pool a pleasure and not a chore.
I have two small issues I would like to have some help with. The first are the little brown circles, copper looking that I have on the pool floor.
The second is that I have "worn" spots on the fiberglass. That is the best way for me to explain it. It looks like the white stuff has just scraped off.
Pictures for reference.

numbers were from Sunday, as I am away from my pool atm.
Thanks in advance for any help here.
