Green Pool Halloween Editing

I’m seeking some assistance with my pool. Last week, the water turned green, and after testing it at Namco, the pH was 8.5 and alkalinity was 306. I added 3 lbs of muriatic acid, which brought the pH down to 7.4 and alkalinity to 250. I also used a robotic cleaner to clear debris, and last night around 6 PM, I applied 3 lbs of granular shock to address the green water.

However, it’s been over 12 hours, and I haven’t noticed much improvement. The pool holds 12,000 gallons. Should I add more shock, or could the high alkalinity be impacting the treatment? I would appreciate any advice on what steps to take next.
