Thats right, but, youd have to see the settup. The refletcor is supported by a length of 1-1/2" closet rod spanning the width of the tank which in turn is supported by 1"x4"x2' vertical on each end that is screwed into 1"x4" that runs the perimeter of the tank kinda acting as a light "shield" and a support system. I wish I could get a pic up... The reflectors about 10" off the water, 250w xm 10k, Coralvue electronic ballast, 185 watts of good old vho actinics.
