sounds good, these seems to basically be everyones opinion. I want to go with MH, so would 2x 150 watt MH be enough? Also, what other bulbs would i need wouldnt i also need VHO's? 1- 10,000k and one actinic bulb as well as the MH? and with that said, i am confused even if i buy a retro kit where is it all made in one pack, how do i use it on my tank? as in do i just screw it into my wood canopy? or.. any suggestions, my wood canopy is only about 9" i would say off my water.... and i could put fans in it, and im not sure that is eought room off the water
