well, i will step in and say this is going to far. new pioneer, i have used the submersible, last i checked , which was a few years ago they were a little pricey. i am sure that if thats what you want to use it is fine. i did have an aquarium in my garage and my fish did not die. i dont look for it to last long if it is under a big strain. it depends on your weather. with that being said there is no need for you to defend your choice. your money, your chickens. they are not going to die. all the safety features in them for fish still apply . nycue, same applies for you. i am sure he can read just fine as can anyone else that is reading these posts. your chickens, your choice. this post was started as someone who was proud of what he had accomplished with his water system. and he tried to share with others. this man apologized to you and you threw it in his face. may i remind everyone this is a SOCIAL network designed to talk chicken and help our neighbor out when we can.
