I bought that setup 4 X 96 fixtures for my 125 gallon in Janurary. I got 2 5000k and 2 6500k - have row in the back of 1 5000k and 1 6500k and then one row in front of 6500k and 5000k to stagure the light...
Great company though, One of the 6500k bulbs broke in transit, they replace it at no cost the next day priority mail.
I plan to order more from them for a 29 gal this week. Hope that helps!
