here is my plan

I buy an $80 50 lb bucket of Chlorine pucks from BJ’s at the start of the season. The bucket will last all season. I shock my pool with bleach almost every Sunday with 2 jugs of bleach. (24,000 gal pool) Swimming season is May through September so bleach cost is about $40.

This method allows me to chlorinate my pool for $120 a season and I am only adding chemicals/pucks once a week. I do test the water 3 times a week though.

I don’t really care about CYA, because I open my pool to 0 CYA at the start of every season.
