Hi,

I'm ordering a custom LED fixture from China for my 30 gallon mixed reef tank. I need a light to have the full spectrum needed for good coral growth and over all look of the light. I've been looking out there for info on the best combination and most of it is outdated (or I'm looking on the wrong spots). I'm in need of a little advice on my combination and what's the newest on led bulbs for the best coral growth and look.

Here's what I got so far.

Channel1: 12 Royal blue 455nm+10 blue 430-440nm+2 blue violet 420nm+2UV400nm+1 red 660nm
Channel2: 8white 6500k+10 white 10000k+6white 3000k+2 red 660nm+2 green 525nm

Tell me what you think and how I can improve it. Should I be going with higher then 10000k on the top end of the spectrum or do I have enough of my bases covered? Also is the blue range 430nm-440nm needed for better visable color or is all royal blue 455nm enough.I found that just royal blue LEDs at night time don't show any of the reds or oranges in the corals, that's why I added a red in the blue channel to bring that back. I'm trying to cover all my bases. Also I have a cyan 495nm bulb available, haven't heard much about it but would it add to the spectrum needed?

Thanks,
Matt
