I have finally ordered my new 120 gal starfire tank with dual external overflows and an 80gal ruge/sump. I still have a couple weeks to go before I pick it up so I'm researching as much as possible. My big dilema is what to use for circulation. External return pump? 1 or 2 submersibles? powerheads? wavemakers? I wanna do this one right. The display tank is 48x24x24 and the sump has 2 drain boxes(one that bypasses the refugium to prevent overcirculation through the refugium)Any advice from experiance would be a big help.
