Hey Kevin, thanks for the quick response.
I'll be going bare bottom- sand bed will be remote, for maintenance purposes..
I guess the 80 degree optics require that they go so close to the water..
If you raised them an inch or two and ran them perpendicular to the tank wouldn't you get better coverage?... I guess you sacrifice intensity if you raise them, but having them perpendicular should spread your light out to the back further, no?
It just seems to me that a source of light that is about a foot in length suspended over the middle of a 30 inch wide tank ends up delivering light to almost the back side of a coral placed near the front of the tank.. Especially if they are running parallel...
This is why I would rather have two rows than run them perpendicular to the tank..
Ridcpa, if I were going 72, there'd be no question in my mind to run 6.... Sure does get pricey..
I'm just wondering if 6 over a 50x32 is over doing it.. I guess Kevin, you wouldn't say I was crazy for doing it..
