Awhile back, I saw a reply that was in the middle of a thread on this forum, where someone commented on the idea of adding extra amounts of liquid chlorine so that you don't have to do it every day. I don't remember where it was, but the argument went something like this: a person was saying that he knew how much FC he should keep in his pool, in relation to the CYA level, but he didn't like the bother of having to add bleach every day, so he would add an extra large amount so that he only needed to do it every 2 of 3 days.
Someone else replied that you should add the right amount every day instead of an extra large dose every 2 or 3 days. The argument was that if you add too much chlorine at one time, the excess chlorine will not get bound to the CYA. Therefore the excess chlorine will burn off fast in the sunlight and just be wasted. That made me wonder if there is a rule of thumb, about how much of the FC in the pool gets bound to the CYA, so that one could know the amount above which the chlorine might be wasted.
I also recall a post from ChemGeek, where he said that the CYA in the pool also seems to act as a shield against UV, so that the FC in the deeper parts of the water seems to be protected from sunlight even if it is not bound to the CYA.
So I realize this is complicated, but just wondering in general about the idea of chlorine being wasted if we put in too much bleach and do it less frequently?
