I'm back! Problems with chlorine and CYA

Hey everyone! You were all so much help last year and I could really use your advice again this year.

Held the chlorine level between 20 and 30 for a few days and the water started clearing up. Added GLB drop n vac on Monday, vacuumed yesterday and added hose water, and today the water is cloudy and tinted light green.

Test results taken a few minutes ago:
Chlorine: 0
pH: 7.5
CYA: below 30 - filled tube all the way to the top, black dot was still completely black

Added 363 oz of 8% bleach after testing

Do I need to raise the CYA? If so, what exactly am I looking for at the pool store? I'm sorry if this has been answered a million times before, I looked around a bit before posting. I'm really not sure where to go from here and any advice would be greatly appreciated.
