Settings for an xr15 G4 pro to grow macro algae

[adtravels]

I am in the situation that I have an xr15 to use as my fuge light.
I have a Seneye as apar meter ad can get a good 150 to 250 par for the fuge.However I wonder if there are any of the led channels I should be dropping to maximize algae growth.
There are a number of presets 14 k gives the highest par readings but has all Channel's maxed out.

The channels are cool white, warm white, blue, deep blue, violet, uv, red and green.

Thanks for any help

I am using ViparSpectra LED's, running the whites at 50% and the R\G\B channel at 40%. Those are working well for me.
