Hi SUSAN, We are the manufacturer of Pool Time products. We appreciate your feedback and are sorry to hear that your recent experience with our Sink to Clear Flocculant fell short of expectations. It is important that the pH of your pool be adjusted to the 7.5 to 8.0 range for best results with this product. After allowing the product to circulate throughout your water for at least two hours, the pump and filter should be turned off, allowing the pool water and debris to settle. After 24 to 48 hours, vacuum the material that has settled at the bottom of the pool to waste. This product should only be used in pools that can be vacuumed to waste. If you would like to discuss your experience in more detail, or if you have any other pool care related questions, please give our Technical Solutions Team a call at 1-800-252-POOL (7665). Thank you.
