T5HO bulbs to get are ATI or Geismann. All other bulbs are a waste of $ in my opinion. My new ATI bulbs should be in next week and I cant wait to get them into the fixture.
its just 2 bulb right? i would think so just raise it to desireed hieght. I have a like 24'' hight aquarium and i put mine on 4x4. Sry i just dont know that much about light!?!?!
