I need some help. I am going to attempt to plumb a 30 gallon and a twenty gallon together. The thirty gallon is on the top of the stand and the twenty is on the bottom. I have a pump and understand how to run pipes to the top tank from the twenty and everything but how do u make the return? Do I need an overflow? Will i have to cut holes in the tank? If I do have to drill holes how do u do it? If u have pictures of ur plumbing and etc. could u please share them. Thanks in advance.
