Led setting for sps

[Kaman8]

My led settings at the is

White 45%
Blue 80%
Rb 100%

But it is still too white for me. I want more on the blue. If I reduce the white to 40% would that be ok for the sps ? My fixture is 6" from the surface. Here is a pic of the spectrum of my fixture.

Try 30% that's what I use to run looks like 20k

You don't mention the ratio the various color LED's are to one another. You could also cut back on the regular blue as well. I would try 100/65/40. Assuming they are evenly paired up.

Is that enough for sps 30%

we need more information. How many diodes do you have? How high off the water are the lights? How low are the coral? What are the tank dimensions? Do you have optics? What degree?

I run my blue at 50% and white at 35%. I had them at 75% and 50% and my coral starting fading out.

Tank dimension is 24x12x18. Light is 6" from water surface. Coral are 3/4 high and some in the middle. At the picture below you can see how many I have and how many watt each.

Only one way to find out. Better to start with too little than too much.
