This has not been my year. I have gotten some great advise on here and I am back for a little more. I am using the BBB method and my numbers are as follows:
Free Cl 16ppm
Total Chlorine 18ppm
My problem is that I have a blue to purple colored stain that goes around the pool at the water level. It comes off of the vinyl liner fairly easy with a little scrubbing. The bigger problem is that it has turned the fiberglass parts (steps, seats) a blue to purple color and it does not want to come off of these parts.
What is causing it, what is it, and what can I use or do to get rid of this?
My thought is that I have some metals in the water and this is causing my problem. They did work on all of the water mains in the neighborhood and I think that I got some metals in the pool when I topped the level off.
I have read the Metal Free bottle and it says that it will remove metals from the water, but what will remove the purple stuff?
Thanks in advance for all of your help
