Please tell me what to do.

My pool water was perfect using the BBB method. I went on vacation. Severe storms came through, knocked out the pool pump, lots of tree stuff (along with a plant, a bull frog and an umbrella) blew into the pool. Neighbor watching pool had a heart attack so I had no idea this was going on. Pool sat for three days.

I have an inground 20,000 gallon vinyl. It is green and cloudy and there is a yellowish film on the bottom of the pool that brushes off easily.

Right now I am reading:

Thanks for any suggestions!!
