I have a 20000 gal AG vinyl liner pool w/ a sand filter. My water was clear when removing the cover. However some of the yucky stuff from the cover made it into the pool and i had a algae bloom the next morning. I have shocked and stabilized. My water remains a cloudy blue/green.

My numbers as of today are:

FC 5
CC .5
TA 290
PH 7.2
Cya 25-30

These numbers are after adding a quart of acid and aerating the pool for the past 2 hours. I can see the bottom but not well.

what else should I do?
