This tank has been running about a month now, I added my first zoas last week. So far everything is doing great. It's a standard 5.5g with 3/4-1" of sand, some old marco dry rock, a aquaclear 50 fuge mod with a aquaclear 20 impeller installed, zoomed 501 canister with purigen, bio media and foam filter. I also added a nice looking backdrop from petco.
