Welcome to tfp, mini 
Have you gotten a sequestrant in the pool to prevent the stain from reforming? It will also require maintenance doses.

Yes, I do. And I plan on doing maintenance doses. Thank You.....When I first had this problem I thought it was dirt scale. Until I came across this site. I tried the vitamin C test and the stain just disappeared. I didn't just have a small spot, this was all over the liner bottom. I got the asorbic acid in powder form. I started the process this weeked. I am amaised how well this works. I am very happy
