Unfortunately, when you get to the stage of piles of algae, it takes HUGE amounts of chlorine to kill everything. That's why physically removing as much as you can is so important.

I think I've mentioned in this thread (I know I have in others this season) that you can't filter live algae. You can kill it, and then filter it. Or you can sometimes remove it, vacuuming to waste. But while it's still alive, your filter can't do much for you.

It's too bad no one is doing bulk chlorine sales to homeowners in this area (NW Georgia). There is a bleach manufacturer in Ranger, GA, not that far from you. But when did business with them, I was buying 4,000 gallons at a time. That's a bit more than you'd want -- even if it WOULD clean your pool right up!

Sorry!
