I have been told you can put bleach or Apple cider vinegar in chickens water to clean and sanitize. I read the ACV is good for worm prevention as well. Does the bleach do anything for the chickens, or is it just to help keep the water clean? What about amounts? I use a 55 gallon drum set 8 foot high to gravity feed all my water lines. How much would you add to 55 gallons? I do have another concern. There is 1/2 inch PVC line that comes from the barrel, through the coops, goes underground then back out again at my water trough for the goats. I use the red drinker cups with the yellow toggle that lets the water out. Those use springs on the toggles. Would bleach or vinegar hurt the springs as far as corrosion is concerned? I am not so much worried about algae. Nothing in the system is clear to allow sunlight to cause algae growth. I have hard water though and I don't want any mineral build up to cause problems. I honestly don't know if it is even an issue because I can't take it apart to look, but I figured a little maintenance would hurt. I obviously can't use commercial drain cleaners. That would definitely not be good. Any advice, or would you just leave it alone?
