help I am building a sump/refugium side by side

[higgz]

I am on a serious budget but I need to build another sump/refugium for my 110 gallon.
I have a 20 gallon long but it is not doing the trick. I have a regular 20 gallon and a 10 gallon that I am not using but would like to. I would like to connect the two tanks together using the 20 for the return and the 10 for the refugium. PLease someone give me some suggestion. I know this a wierd thing but I know some one out there has put two 20 gallons side by side. I just have not seen it yet.
Thanks for your help,
Greg

drain in the 10G, return in the 20G, just drill the tanks on the side and connect them with flexible hose.
