We did not cover our 28' above ground pool last Winter. (I KNOW BIG BOO BOO)

Needless to say it was filthy, leaves, green beyond belief. WE drained most of water then added fresh. Treated w shock, nice blue color but super cloudy. Lots of vacuuming, backwashing and still blue but cloudy....last week almost overnight turned green. Added 6 packs of super shock pool STILL GREEN test strip/kit says;
free chlorine 0/0
ph off the charts high past the 8.4 range which is max
alkalinity 40
hardness 200 which seems good?
cya 30-50
HELP what is my next step?

I am single mom and don't have a clue what I Am doing lol- I heard regular home bleach might help I cannot afford all these chemicals for such a big pool... thanks for any insight
