I made the mistake of following package instructions on Home Depot CYA granules and sprinkled directly into pool. It's all collected at bottom of deep end and I'm worried about staining to our new (dark colored liner). I have the pump running continuously to help with distribution and dissolving but it's been half a day and the granules doesn't seem to be going anywhere soon ... I added the CYA in advance of closing for the winter. Assume it is better to wait until all granules dissolve before covering/closing? How long will it take and anything I can do to save the liner?
