DUH

As I was putting down mulch today I looked under the cover to see if it was still clear like a week ago. NO DICE. It was green water. We have had 4 nice days after a bad cool snap so I thought I was safe.

I followed the winter closing instructions to a T. I just forgot how to open, in particular with the chemicals. With the apparent algae bloom what am I up against? What steps should I take?

Thanks as always!!
