We just use those test strips in the bottle...we have used them for 5 years and never had a problem. (I know some people like the more "professional" testing method, but we are pretty much sticking with the strips).

How much chlorine should we be adding at a time now to build the chlorine level...do we still use the regular 'shock" some say "super shock" envelope packages to dump in or is that too much at a time?
