T5 lighting….what do you have?

[Amadod2]

So with my current full change up on the tank i have decided to change up the lighting as well, i wasn't getting the greatest results for my corals after a year and i know way, here is the current lighting set up:

6 bulb t5 fixture

5 supper blue and one fiji purple

now looking at everything, there was no real coral growth, just had the blue look i liked. but now i have realized that it needs to be changed.
So what are your bulb combos, and what gives you the best look with coral growth?
