lighting - how high of a hood...

[bkent]

I want to build a DIY hood for my 125 to make it into a reef tank. These reflectors claim you can use 2 MH for a 6 ft tank.

If this would work, getting 2 MH instead of 3 for my 125 would save $$. Do you guys think I could effectivly light my 125 with 2 MH using these reflectors?

Some camaros came with six cylinder engines, but the don't go as fast...Wanna cruise, or race?

My understanding is one halide per 2 ft of tank. If yours is 6 feet then you need three lights. Thats what i was advised when I bought mine and what I have seen posted...

The general rule of thumb is one per two feet of course. I am just currently putting in three spideys on a six foot, but it is a bowfront with crossbars. I suppose if I didn't have those to deal with, I would live with the two-lamp fixture I have right now, as it lights sufficiently, and leaves somewhat less lit areas on the ends for mushrooms and stuff.

The middle will still receive quite a bit of light, You could place the softies in the middle. I have seen tanks with 2 and there doesn't seem to be much light loss in the center. the reflectors make big differnce with lighting IMO.
