just took over my pool maintenance after the service guy quality been going down and prices going up. first 2 weeks I got the pool looking best I’ve seeing it in a while.

when I took over it, I noticed a few spots that lead me to believe it’s calcium build up but can’t definetly say what they are. Have to dive and take a closer look.

These are at the 6’ deep end.

what could these be? calcium build up?
If so how can I remove them?

also noticed 2 spots where they look like copper stain.. what can use for those?
Pebble inground pool. 18,500 gallons.
