Yeah, I'd say that covers algae

Me too!!!
Yes, it is wonderful, when I can go to Walmart and spend less than $10 to get what would cost me close to $50 or more at the pool store!! I saw the Manager of our Leslies at WM the other night, he looked at all the bleach in my basket( we were fighting algae) and asked what I was cleaning, I said "my pool" I thought he was gonna heave right there!! He asked me if it was working I said, I dunno, just got home from vacation and have a green pool, why don't you come by in a day or so and see??"
He shook his head and walked away!
