Wife added CYA to pool by pouring granules into a bucket of water, mixing, and ten broadcasting directly into pool. I came out a few minutes after she did this and saw that the granules were sitting on the liner. I had son vacum the granules, while I did something else around the house. Came outside to check to see how he did and I found my Hayward 1HP pump running very loud. Any Ideas whats going on.I have shut the pump off.
Please have some good news for me.
