    If it's dark in color (obviously) and/or rough, it may be scale from excess calcium. Can you post a full set of water test results?

    You've already tried vitamin C, so now you can try a tri-chlor puck on the area to see if it's organic. As a last resort, there are some over-the-counter methods to ID a stain (i.e. Jack’s Magic Stain ID Kit – about $15) that can be used to help identify the cause of a stain.

    I did try a puck! No luck. Also...my calcium is just a tad bit high at 725! Lol, i am draining pool in a month or two. We had that stain when we draines 4 years ago, how can i get rid of it if it is calcium scale?

    Dry acid in a sock. But, that isn't calcium scale. Try putting a Vit C tablet or two on there and leaving it until it dissolves.

    Oh, I see. It looked like it was on a step at first. That is a little trickier.

    I don't think it is scale. You can get some dry acid, sodium bisulfate, and put it in a sock and rub it in the stain. Is it rough or raised texture?
