I've always wondered about the CYA/CL charts' use of the word "target." Is the "target' the level you "aim for" when you add chlorine -- i.e. the highest "non-shock" level you should use -- or is it the "average" level that you try to make your FC levels center around over time? I understand that ideal levels will vary from one pool to the next, but I'm just asking for clarification of the term as it is used in the charts.
Thanks,
