I have an Intec easy set 18' x 48" deep pool. I took the CYA granuals and put them in a bucket with hot water to try to break them down. Then after the water cooled I took the bucket and lowered it into the pool. Its been 36 hours and I am still showing 0 CYA. Last year I made the mistake of dumping the granuals into the pool and stained the bottom. Therefore, the idea of leaving it in the bucket and setting it in. Thank you.
