Watermom, Since my pump still hasn't arrived, I took your advice and I added a gallon on bleach yesterday to the pool and stirred it up with my net. When I woke up this morning, most of the green algae was gone. Now it is like a cloudy white. So I went to my supermarket and bought more bleach. Today I just added another gallon of bleach. Let's see what I wake up to tomorrow morning. My pump should hopefully arrive on Monday. In the meantime I am going to add a bottle of bleach per day and maybe I wont have to drain the pool after all.

Thanks for your help and suggestions.
