Hello,
I have two 55 gallon drums that I used for saltwater mixing station. The fresh water drum has a flow valve installed to automatically shut off your RO/DI unit. They are connected together via PCV pipes, valves, and a mag5 pump. I am selling everything for only $50 (basically for the price of the mag5 pump). If you don't want the mag5 pump, then you can have the entire mixing station for FREE.
