I just picked up a 56 gallon tank, which measures 36X18X24. I really like the size of the tank and just the whole feel of this operation, with the exception of the center brace. I use a 150 watt Coralife HQI Metal Halide light that has the lovely hang on clamp. Now my problem is that I cannot get the pendant dead center on the tank, the center brace is in the way for the clamp. So I have two options now, buy another and use two on the tank upping the wattage to 300w or just using it alittle off center. Now my last question is, if I do use the light alittle off center will I be getting alot of light into the tank? 150/56= 2.67 WPG, which is fine in theory but will I be able to get all those watts into the tank? Thanks in advance.
