What chlorine level are you generally trying to maintain day to day? 3-4ppm? Do you just get used to knowing how much dichlor (or bleach) to add after each use to get it back to 3-4ppm?
Further, do you in fact usually add a little dichlor after -every- use? Or do you wait 2-3 days? (going with the assumption that you use the tub daily for maybe 30 mins, 2-3 people).
And then, how often do you shock? Once per week? What level do you aim for when shocking, 10ppm?
Lastly, when and how do you use MPS? Just as part of your shock? Or do most people not bother with it at all and just stick to chlorine?
Thanks!!!
