Thanks Janet - do you mean keep FC 12-15ppm and not worry so much about the total chlorine level ( the FC added to my CC level)? because those seem kind of high lately. will i bleach out my liner or is that not true? I am surprised by how high my cc levels were getting - and it is now day 10 of the conversion. What does that mean? I remember reading somewhere on the forum that you can raise cc levels by inadequate shocking. Am i making it all worse by adding too little? Thanks. aciam
