i bought a 40b from petco for a qt setup. after seeing how my captain americas reacted to my new light fixture im having thoughts of setting up a low tech zoa/paly garden. no fish just zoas and a cuc no sand and minimal rock. so i was wondering what i really NEEDED to be sucsessful. i have 2 k425 nanos that i can put in for flow. i also have the light and a hob tetra filter im figuring i can use for carbon? no skimmers or reactors. would this work? or just be more of a PITA than its worth?
