after years of buying the steel tanks and having them rust out, tried a couple of the black rubbermaid ones.
Not looking like that was a great idea either, have alot of red growth that comes back fairly quick. Is
there anything to put in the tank to help with this? Have a bag of copper sulfate here, but would
have a couple angry women around if that wasn't compatible with their horses.
