Hi CGPool, 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 Flocculent did not meet your expectations. The pH level is critically important when using this product, with a recommended pH of 7.5 to 8.0, for best results with the Sink to Clear Flocculent. If the pH was lower than 7.5, the product may not perform as expected. If you would like to troubleshoot your pool's specific cloudy water issues or if you have any other pool care related questions or concerns, please give our Technical Solutions Team a call at 1-800-252-POOL (7665).
