So I was about to add CYA to my pool last week. I'm sitting there thinking "I don't really want to put this sock in my skimmer, but I'm too lazy to string it up in front of my return. Then it hit me. Drop the sock in my PoolSkim! It worked perfectly. So if you have a PoolSkim, think about it if you are adding CYA!
For clarification, it stayed in the white cylinder and never got blown into the net part of the PoolSkim.
