I have two 20 gal tank as shown in the picture. One is on top of the other one however I want to have a PVC pipe that flows down the the bottom one and than the bottom tank pumps up the water with a water pump to the the top tank therefor they share water conditions. I'm not sure how I want to to connect them. Any ideas, thoughts or ways I can get an overflow from the top tank?
