I came from the pool world. Pool gone now but knowledge still lingers.
City water usually has 1-3 ppm of free chlorine. Been drinking it for years and years and still here. Adding 1/2 tablespoon of 6% bleach to 5 gallons of water will raise the free chlorine to 25 ppm. I wouldn't want to drink that.
The problem you are going to have is that the UV from sunlight breaks down free chlorine and it will dissapate within hours if sitting in direct sunlight. If it sits in a barn or room with no direct sunlight, it might make it all day without dropping to 0 ppm.
If your using city water that's already chlorinated, I wouldn't worry about adding bleach. Now if you want to try to clean the system once in a while by raising the FC to shock levels by running water through the system, that would be fine but don't let anything drink from it while you are "cleaning it out". If you have any metal in the system, the metal isn't going to like the raised levels of chlorine.
If your using well water then you can add some bleach to the water to sanitize the water. It takes ~18 drops of 6% bleach to raise the FC 3 ppm in 5 gallons of water. So 1 drop of bleach per gallon = 1 ppm FC as a general guide. If you have copper in your well water, the water may turn green from the chlorine, don't remember if it will at those low concentrations or not.
Do you ordinarily have calcium scale problems with your water or something?
