Yeah I'm got the rest of the aquarium equipment at home waiting on me to get their.
I am planing on putting an external pump that supply's water to all of my top level 20 gallons and than when it ends at the 2 55 gallons on the left side. Each tank will have an over flow to the tank below and the floor tanks will also have an over flow that will all drain into a single drain that is piped back into the sump. The return will Also have a submerged pump in the sump because the water has to be about 12 off the ground to get back into the sump. I'll have to force the water up after the bottom aquarium have drained. If that does not work than I'll have to figure out something else. Fingers crossed it works though
