    Iron stain test photo

    I thought I had tannin stains, so I decided to try the iron stain test. Below is a single 1gram ascorbic acid tablet (Airborne, actually) after 60 seconds. Notice the "comet trail" surroundings the tablet.

    My Pool: 18'x36' Grecian. Vinyl Liner, 500# sand filter, SWG.

    My hobbies: Brewing beer and flying rockets.
