You have 2x96 over your tank? If that is the case I believe you are under lighted there. I think wpg is highly over-rated!! My recent approach is to almost over light and adjust on time. I imagine you are having a light spread issue with the 2x96. I have 2x55 + 2x13 in my 46 but the 26 from the 2x13 is worthless IMO. I would like to use 2x96 on my 46 for light spread. I think if you put 4x55 over your tank, you will be right where you need to be.
Oh, did you say 6 hours. What about 10 hours?
