Well thanks for the warm welcome. I guess im going to start mall and do a 65 rectangular tank. Nothing to serious. I am going to set up an overflow and sump system with a live rock and live sand filtration, a protein skimmer, and a physical filtration. I guess i am having issues with the overflow with correct pipe dimension to figure out flow into the sump to get the correct pump for the return line. Anyway you guys can help me out already? haha
