Well, I did the Vitamin C test on my steps. I definitely took the stain away. This means it's metal, right (pool store said it didn't have any)? I added a bottle of Metal Magic and brought my pH down to 7.2. Is it possible that the stains will lift just by adding that? I still have a lot of "stuff" on the bottom of the pool. I think they are two different problems. Can I bring the CL up to shock without affecting the sequesterer? I've read where high CL can make the metals fall out of the water. I guess I need to clear up the water before I address the metals? Any direction would be greatly appreciated.
Thanks,
Brad
