I have searched and found multiple threads for adding CYA. My new liner was finished up yesterday. Pool should be done filling tonight. I will test the water to be certain what amount of each chemical I will need before adding anything. Knowing this water is tap water, I am assuming there is no CYA in the water. If I go by what the Pool Calc says it says to add 22lbs of CYA. Here is where my question comes in. All the threads I have read a searched all say add CYA by sock in skimmer, or by sock in front of a return or mix in a bucket. However, these threads are usually talking about a pound or less of CYA. Makes sense. If I am adding 22lbs of CYA, what is the best method to dissolved that amount of CYA into the water as quickly as possible to get my pool up an usable?
