run the pump 24/7 while shocking. because cya's of 40 and 50 are so close on the chart, I would shoot for minimum and target levels of 50ppm (4 and 6ppm), and I probably would shoot for the 50ppm shock level also, though you could probably split the difference there and go with 18ppm shock level instead of 20 if you want. 20 should make it go slightly faster.
