My Innovative Marine Stepdown Tank

[Josh Jordan]

Started in July 2017, my 20 gal stepdown reef is thriving with lots of small fish and some really nice frags! I have a pair of bangii cardinals, sharknose goby, red scooter blenny, Catalina Goby, hi-finned redbanded shrimp goby and the smallest yellow tang I’ve ever seen! For filtration I have purigen, seagel, denitrate, and matrix for biofiltration. Thanks for looking!
