Ai prime had settings help

[Reef donkey]

I currently have a 20 gallon 24x24x6 frag tank set up and I have an Ai prime hd on it. I having trouble find information on the best lighting percentages for optimal growth. I have strictly zoanthids in the tank right now. The ones that have been in the longest seem to be much brighter and losing some of the darker colors in them. Could this be from too much light? The light is mounted on a 12 flex arm above the tank and I currently run all the blues and purples at 45% from 6am to 12 am and the white and greens from 10am to 2pm at 30%. I don't have a par meter so I'm not certain what the pats might be. Does anybody have any idea on what the lighting should be at or the amount of time? I am new to drag tanks so Any help would be appreciated

My prime HD is over a 40 gallon NUVO which is 24x20x19 and lights it just fine. I currently have it set to 15.5k. If you go into the manual settings on the top right corner of the screen there is a little semi-circle. If you click on that it'll bring up the sliding scale where you can select brightness and color spectrum. Remember the settings, and apply as desired.

This is what I have over a 20 gallon tank. Mostly softies and LPS.

thank you I will give it those settings a try! Do you see good growth?

I see good growth at this setting, no bleaching. Keep in mind that I have a clam in the tank and I started cranking up the lights slowly after I got the clam.
