I had Yellow Mustard Alage. The pool store reccommended Yellow Stuff, by Jacks Magic. My water is crystal clear, but there was yellow stain blotches around the bottom of the liner. My pool is 12' X 20", 8,200 gallons. I then went back and they reccommended that I use EZ-Clor - Metal Magnet- $16.99 for a quart. They reccommended I use the quart in my pool. I did and then they reccommended I use 2 pounds of Pool Stain Treat - United Chemicals - Abscorbic Acid. Mix 4 gallons water to 1 pound Abscorbic Acid, shut down pump and pour mixture into pool where the stains are. I did and nothing happened. I was told that the mixture would sink down to the bottom and remove the yellowinsh stains. It did not work. I still have the stains and I have spent over $80 dollars and I still have the stains.

Confused by bad advice.

P.S. Is this problem fixable? I have gotten into the pool and scrubbed the stains with a brush with no help. My wife and kids refuse to get into the pool untill I get rid of the stains.
