Ok that's a makes perfect sense on the light matter. Is it the Bluetooth dimming capability or the standard T5 ? So I am imaging that there are three different power cord coming out of the light fixture or four , a cord per pair of ballast. Sorry I am only asking these question is cuz I picked up a standard 75g 48x18x20in tank that I'll be installing a ghost overflow on and I am looking a lot at T5 lighting . And I am in between 4,6,8 bulb. More leaning towards 6,8 bulbs . Which would you recommend ? I am really loving the look of the Matrixx over the "metal box lighting " quoted from another Reefer lol . But in reality all I want is success this will be my first reef build that I am planning.
