Lighting intensity for mixed reef nano with 20% sps

[GulfReefer]

Hi
What would be the ideal light intensity for mixed reef tank with 20% to 30% sps without compromising tank to algae/diatoms/detritus etc. my current setup as follows
UV set at 100%
Royal blue 100%
Blue 100%
green 0%
white 0%
red 0%
note that as of now i do not have any sps only Lps that is why im not using white/green/red colors
However this will probably needs to change once i introduce sps frags to tank.

Without knowing tank dimensions and light used, its hard to tell

The tank is cube 20Lx20Wx20H
Light is Maxspect Jump MJ-L165 Blue Led

One that gives each LPS and sps there needed PAR and spectrum. Grab or rent yourself a meter and you will be able to dial it in. Otherwise you can play it by sight and reactions of corals

I second mtrayler on the par meter. It just removes the guessing. I finally got one when I started with sps and was surprised how low my readings were even tho the lights looked bright. It also explained why I failed at keeping a clam alive.
