I would like to have a few people get envolved in this question. Please all reply. How do i use bleach to keep water in the chickens and goats pens clean. I have 2 water containers i use one 10 gallon tank and the other 15 gallon tank. I need those 2 tanks clean w/ clean water to give to animals. So whats the break down on bleach per each gallon of water?? Thanks to all that reply and know that this backyard web forrum is the best and is the only informational tool i use for my animals questions and reseach.
