I am still working on my 180 build the stand and canopy are finished and about to be stained. The question I have or the opinion Im looking for is about lighting. How many 96 watt bulbs would be considered high lighting 2-4-6-8 and how long should they be on for and should the color temp change( a couple 6700 and a couple 10000 ) I am at the point of mounting lighting in the canopy and only want to do this once. The tank will have a bed of flourite and presserized C02.
