i just set up a nano in my room, kinda in a mini cycle. i also have a 29 hex sitting in my room with all my zoas. it has a 150 watt MH clamp on. the jbj 28 also has a 150 watt. i kept them both on today and man was it bright in here. 2 14K bulbs! i kinda do not want to take the risk of both of them set up, so i am moving my zoas to my nano, and prob selling the hex..
def get the jbj 28 gal. i love it!
