Another method is to fill a 5 gallon Home Depot Bucket with pool water, add the CYA and cover it for a few days, stirring or mixing it every once in a while. Then pour off the disolved liquid directly into the pool, being careful not to dump the undisolved granules into the pool. Then re-fill the bucket with more pool water to dissolve the remaining granules. Repeat as necessary untill all disolved.
