I built an 80 gallon shallow reef aquarium at Marine Depot back in 2014 and documented it over the course of 6 video episodes. It's been a terrific tank but our fishes and corals have grown and are ready for more space. We've decided to transfer all our livestock from the old tank—plus a huge collection of frags I've been growing—into a brand new 139 gallon system. This is the first installment of our new Reefer Deluxe 525 XL video series so please subscribe and follow along! We'll be adding an aquarium controller, calcium reactor, algae reactor and more in future episodes.
