Set up my first 55 gal tank in January 2018. It has a Cascade 700 outside enclosed filter system. My plants are coming along slowly. I use Eco Complete Planted Black Aquarium Substrate and
Seachem Flourish At first I had to fight with brown algae but that has improved. I currently have 5 rainbows , 3 albino Congo tetras, 2 long tail Congo tetras, 3 emerald green Cory, one bristle nose pleco, and one rubber lip pleco. I’m thoroughly enjoying my tank.
