I just got a 75 that I'm starting to put together now to consolidate my two tanks. I have an Aqua C Urchin pro and a Euro-Reef ES5-2. I saw that the ES5-2 is rated for 40+ but the Urchin Pro is rated 75+. I was wondering about which one I should run for should I try to run both? If I run both I'll be making a new sump.
