I have been using liquid chlorine to open my pool and took it to slam level. Now that it is down what number should I be kicking my SWG on? I have my FC @ 9.4. 9-11 is pool maths daily target numbers.

Im thinking I should kick it on 20% now to see how much it jumps. Not planning on swimming anytime soon. Have not used it yet so Im getting antsy..

What FC number you are targeting depends on your CYA. As for %run time for the SWG, that may just take some tinkering. I'd start at 20% and see how much your chlorine drops. I know I've let mine drop too low by not checking when coming down from SLAM and running at 20%, so just be sure to check and you'll get a feel for daily consumption of FC as production of FC by SWG.
