This is my 160 gallon setup. It runs a dual overflow, with a 33 gallon tank used as a sump. Substrate is a #2 silica. Residents include 2 Jack Dempsey Cichlids named Spike and Jack, 2 Tiger Oscars named Mufasa and Simba, 2 Albino Oscars named Willy and Finn, a Flying Fox fish named Pepe, and a Sailfin Pleco named Big Guy. Feedback, tips, constructive criticism welcome. Enjoy!
