I have some stains on my PebbleTec that began last summer and are increasing in numbers THIS summer. It's been suggested to try Jack's Magic Stain ID Kit. I read reviews on this product and there are a lot of good reviews and results, but some people said it actually CAUSED some stains in their pool that they did not previously have. So obviously now I am a bit hesitant to try it.
Has anyone actually tried this product and what were YOUR results? Did it CAUSE any staining?
