Led bulb choices need input.

If it were me I would not have the 480 nm Blues and greens on the same channel as your whites. You are going to want independent control of them.

Also I would go with 4 UV's instead of 2. All of the reading I have done also suggests that UV has a huge role in SPS coloration. I am going to be doubling the UV LED's in my existing build.

What would you channels and combination look like if it was yours?

[Seth81]

Channel 1: Whites: 12 7500K cool whites, 4x4500k neutral whites,
Channel 2: Actinic: 22 x 450nm royal blues, 2 x 430-440nm deep blues, 4 x 420nm violet, 2 x 4 400nm UV.
Channel 3: Accent: 2 x 520nm green, 4 x 480nm blue, 1 x 660nm deep reds (if you insist on having these)

Also What currents are you running these on? I have independent control of my neutral and cool whites, when I shift the light to the warmer side of the spectrum (like what your red LED will do) it honestly makes the tank look like garbage.

The previous company didn't have enough channels so I have found another distributor with up to 4 channels. This fixture has 36 spots which equals out to 108 watts. I've changed up the combination and channels, tell me what you think?


Channel 1 Whites: 4 4500k warm white, 8 7500k neutral white
Channel 2 Atinics: 8 450nm royal blue, 2 430-440nm deep blue, 4 420nm violet, 4 400nm uv
Channel 3 green accents: 2 520 green
Channel 4 blue accents: 4 480nm blue

Channels 3 and 4 are still up in the air not sure the right combo here. I would like to skip the red like you were mentioning. I can adjust the 4 480nm channel to get the orange and reds to pop when just the atinics are on. I was wondering if the UV and violet already get those colors to pop (I haven't played with these spectrums yet?

Thanks,
Matt

If you can have 4 channels I would suggest slipting your NW and CW so that you have independent control. Also whatbis thr dimensions of your tank.

I dont have any experience with green or plan blue. But the true violet and uv really make the greens pop.

I posted a pic on my diy thread showing what uv does.UV helps to bring out that iridescent glow in sps. Also UV helps with coral coloration. The effect is not super noticable with the whites on. At night my RB TVs and UVs start off at 100% then slowly the RBs fade leaving the TVs and UVs sty at 100% the tank turns purple and the very subtle iridescent colors stand out. Its so cool to see.

My tank is 30 gallons the diamensions are 32"x18"x20".

So is this the scheme your thinking of?

Channel 1 Whites: 4 4500k
Channel 2 Cool whites: 8 7500k
Channel 3 Atinics: 8 450nm royal blue, 2 430-440nm deep blue, 4 420nm violet, 4 400nm uv
Channel 4 blue accents: 4 480nm blue 2 520 green

Or this one is a little different but might allow for more adjustment.

Channel 1 Whites: 4 4500k, 2 520 green
Channel 2 Cool whites: 8 7500k,
Channel 3 Atinics: 8 450nm royal blue, 2 430-440nm deep blue, 4 480nm blue
Channel 4 UV/violet: 4 420nm violet, 4 400nm uv

Just wondering if you guys have looked into the Ocean Coral White ratio?
