I have a similar but not exactly the same light. Mine is a 48" Current Orbit Marine Pro that I bought in March 2016. I agree with the posts above that your issue is more with the age of the tank than the light. My tank was about 6 months old when I put this light on it and there were still some new tank uglies happening then. The tank is much nicer looking now and I think it has more to do with maturity tan anything else. Here's a recent picture:
You can see this tank is all softies, LPS and a few low light SPS. Here's my light schedule, but it may not directly correlate with yours since they're not exactly that same light:
Photo period: 9 hours
Blue Channel intensity: 63%
White Channel Intensity: 60%
Sunrise/set time: 30 minutes
Moonlight intensity: 10% blue, 0% white
Moonlight duration: 3 hours
Overall I've been very happy with my light. The white channel has reds built in that I think make the colors look muddy, but I don't like a real blue looking tank so I'll live with it. I will say that the blue only moonlight time looks awesome. All of the zoanthids really pop during moon time.
I hope this helps,
