Thanks Steven for the folow up info. You just gave me a reason to replace that rubbermaid with an IBC Tote. (Like I needed a reason hehehe.)

Good day Steven,

  Could you send me the reference/ source material that you refer to when you make the statement:

"The tanks you are using are rubbermaid, those tanks are not NSF approved! Those stock tanks can leach BPA and other chemicals into your water, and eventually your fish, and plants. I know they let stock animals drink out of them, but I don,t want to…"

as I use rubbermaid stock tanks in a couple of my systems.
