I have the instructions for this reagent but my question is when you use a non-chlorine shock to shock the pool, how long do you wait to use this reagent to get and accurate FC reading, and CC reading. Do you test right after you shock the pool, do you wait an hour, or do you wait 6hrs (which is our turn-over rate)? I work at a school so we use the non-chlorine shock so they can use the pool all day. Any help would be appreciated. We use the Taylor 2006 test kit. Thanks
