Still continuing to work my iron staining problem. I have some interesting results from the iron testing that I am doing. I want to run some things by the group to get their experiences.
I have been trying to track down the source of the iron getting into my pool. So, I have been testing sources. I tested the city water (negative), the rain water (negative). I then decided on a whim to test the salt I use for my SWG. I use the standard Morton's Pool Salt.
When I tested the pool salt (dissolved in a solution) it read 0.30 ppm Iron. I know you can get iron from salt, but I always figured that Pool Salt would be free of iron. Surprising result to be sure.
What has been your experience with salt and iron content therein? What salt can I buy where the iron content is assured to be minimum or none??
