Ok yall I have been battling algae for some time and and just when I think I have it under control I am at a loss once again... I have shocked over and have finally killed all of my algae. However I now have a brown dusting in the center of my pool (dead algae) that WILL NOT suck into the bag of my vacuum. The algae is such a fine dusting that it blows right through the vacuum bag. Now what? Please help! Im ready to tear the pool down and sell it. It is an intex metal frame above ground pool. 18'x48"
