I am trying to find people who are using an aquarium as their fish tank. I want to use a 40 to 60 gallon tank at a relatively normal display height, maybe a little higher to gravity feed water to my system. I am trying to figure out the best way to do this so if you are using an aquarium please upload a picture, I would love to see it. Specifically I would like to see how water is getting out of the tank. I want to avoid running two pumps if possible and I am planning on having a sump tank under the aquarium with a pump feeding the fish tank.
