I need to add CYA. Last time I used a nylon knee high and squeezed...but it got a hole and some CYA powder went down the side of the pool. I think it left a streak down the side and bottom...maybe it's just my eyes, but I don't want any chance of that again. Can I just pre-dilute the CYA in a 5 gallon bucket and then slowly add to the pool by floating the bucket?
