Just trying to make sure doing everything correctly

Pump runs 12 hrs per day
DE Hayward Pool inground vinyl 23000
Check all readings weekly unless heavy use or grandchildren home
Check chlorine daily and adjust to back above 5
Water 82-84 Full sun
Vacuum at least three times a week
Other than that do nothing else - so my questions trying to get answered

IS THIS ALL I NEED TO DO ?

You said don't add algaecide unless you have algae issue or if driving FC low for stain removal - So think I understand that now

Do I ever shock ? If so when and how ?

Yes the birds are nasty and am sure others have experienced this . Any solution?
