Btw.. I was using a 8 g container for my water reservoir ..It would last 2-3 days max! . So I got a 37g column tank! I got a friend to make me a top for the tank and boom new reservoir ..well that big thing Does not fit under the tank so.... I drilled a whole in the wall big enough to fit a wire and an ro-di tube. The reservoir fits perfectly under my kitchen table and my tank is directly on the other side . I covered the tank in green contact paper (to block light) and labeled the gallons .
