I have this lighting combination right now on my 92 gallons bowfront if you want to come by and take a look:
*One 46.5" T5 Actinic Blue(look violet/bluish mix) HO
*One 34.5" T5 GE 65K HO
*One 24" T12 URI Superactinic VHO
*One 18" PC Smartlight (Half Daylight/Half Blue Actinic.)

The T5 look very bright, but I only have one t5 daylight bulb for the whole tank, so there's not enough coverage. It still looks pretty good over all w/ the above combination. I would like to add some more 34.5 inches 65K T5 if I can afford to.
