Hi TOTAL WASTE, We are the manufacturer of Pool Time products. We appreciate your feedback and are sorry to hear that your recent experience with our 3-in-1 Surface Solution fell short of expectation. Metal stains within a pool, like other types of stains outside of a pool, are most easily treated when the stain is fresh. Once a stain has become set, it is generally more difficult to remove. When dealing with stains that are more difficult to remove, we recommend balancing your pool's pH to 7.2, which is the low side of the ideal pH range (7.2 to 7.6), and brushing the affected area frequently. Additional applications of this product may be added to help lift the stain. If you would like to discuss your pool stains in more detail, or if you have other pool care related questions, please give our Technical Solutions Team a call at 1-800-252-POOL (7665). Thank you.
