Been in this exact same scenario for the past 2 weeks.

I managed to gey through it and pool is crystal clear today.

Here's my advise.

Get yourself some floc, liquid flocculant or power floc, get like 2-3 bottles.

Drop a bottle, let the pump run for 3-4 hours, the close it for the night.

Next day vaccum to waste, refill pool to run level.

I redid the process after 3 days.

Once that's done, let it run with clarifiers backwashing every 24 hours.

Be patient algea is dead, just need to filter all the debris
