Actually, Anna, if she puts the stabilizer in a stocking in front of the return jet, it doesn't matter if she backwashes. It is only necessary to avoid backwashing for a week or so if you add the stabilizer directly into the skimmer and let it dissolve in the filter. In that case, the reason you don't want to backwash is because you'll end up just throwing the undissolved CYA out.
