I need to add CYA to my pool. I believe that I have read in other posts where people put the CYA into a sock and tie it near a return. Why? Can't I just broadcast it into the pool?

JasonLion said:It is common to add CYA first thing in the spring when openning the pool. Half the time there will be lots of algae and no CYA. Fighting the algae requires backwashing frequently, so the CYA can't go in the filter. By the time everything is back to normal and frequent backwashing is no longer required there is rarely any need for more CYA.
The other thing that happens is that people don't expect to need to backwash so they add CYA to the filter. Then two days later there is some sudden reason to backwash and the CYA is forgotten about, so the half or so still left in the filter goes down the drain.
It ends up being simpler to always use a sock, instead of trying to remember that you shouldn't backwash.
