I've been following your thread, watching your slam and understand your impatience. My pool wasn't green just so cloudy couldn't see past a couple of inches to begin with. After finding TFP, I slammed it, and it took several weeks, lots and lots of filtering. I finally used the knee highs and just kept cleaning my cartridge filters as needed and my water now is crystal clear. I think a lot of mine was from all the "shock" we had put in prior to finding TFP. This method does work. Just hang in there. Good Luck!
