I've done some reading in here and i have a basic dropper test kit.
PH 7.4
Alk 100
CYA 55 using the disappearing dot method it has
35k gallon pool

pool is green and can't see the bottom. So i bought 12 gallons of bleach and put in 6 gallons all at once and even threw in a bag of extra chlorine shock i had. Did that at night and let pump run through night. Added 4 more gallons of bleach in the morning even though there was NO change in pool color at all. I don't really have a way to test pool chlorine after it's over 5ppm. But I have to imagine it's quite high. i have chlorine pucks in the pump basket.
I vacuumed the bottom today with pump to waste, backwashed filter and let it run some more. I just flat out have not got the results that some people are posting in here. 0% change.
