I recently got a 120g tank (48x24x24) and it has a corner overflow. There are two holes in the bottom of the overflow. I have sealed one of the holes, and the other I am going to be using as my intake for a wet dry filter. What I am doing is filling the overflow with bioballs, filter floss, and other BB breeding grounds. So my question is, since this will be the "dry" portion of my wet dry, can I just put my pump into a trash can or something and let the water drain into it and pump it back into the tank? I will also be running 2 canister filters on the tank (xp3, eheim 2213). The pump that I plan on using is rated at around 1000 gallons per hour. The pipe that will be feeding to the pump is 1.5" pvc.
