Mine is a home made jobber,  had 6 T5s over it when it was over the 200g tank,  but tossing it over the 300g tub I reduced it to 4 T5s, but the LED side upgraded from my homemade ones to Radions g4pros.   The move was more for aesthetic reasons though as I wanted everything to fit within my aluminum frame that's hanging over the tub.
That said, currently is 2 UVL super actinic, 1 ATI blue plus and 1 ATI coral plus.   Overall it's a fine combo, I had the actinic ones primarily because they were sitting in a closet, but if I were to change I'd probably swap out the atinics for more blue plus then I can use the LEDs to whiten things up to my desire as the white channels currently max at around 24% or whatever the AB+ program is.
