If you are going to need to backwash then bite the bullet and realize that you ARE going to lose some CYA, if from nothing else but the water removed and replaced during backwashing. A sock MIGHT help but I believe that Jason is right and much of the CYA that leaves the sock ends up in the filter anyway since it will take a week for it really all to dissolve. At least the CYA in the sock is still in the pool but bottom line is that you will most likely need to add moer CYA anyway after testing the water once it's all dissovled since you will lose some of it.
Once again, THIS is a special case and is NOT the recommended way to add CYA if you are only trying to increase the level. THAT is what I would like to see stressed!!!!!!
