Hi all. Now that I've taken care of my filter problem, I have to deal with the constant yellow algae that is in my pool. A lot of it is "stuck on", no matter how many times I brush or vacuum it. I keep the chlorine floater filled and run the pump roughly 8-10 hours a day now. It's still too cold to swim in (~60 degrees), so I can't get up close and personal with a smaller brush. What should I do to get rid of it? I've seen posts about using bleach and muriatic acid and the like. My pool is 25,000 gallons.
