Looking for recommendations on light settings

Happy New Year Everyone!

I just replaced the PAR38 light on my 8g LPS cube with the Maxspect C35. It's 4 channels are:

-A Super Actinic (x2)410nm, (x2)420nm, (x2)430nm
-B Blue (x2)445nm, (x2)465nm, (x2)485nm
-C White (1)5000k Cool White, (1)3000k Warm White, (1)660nm Hyper Red
-D White (1)5000k Cool White, (1)3000k Warm White, (1)500nm Cyan

I need some recommendations on light cycle settings. It is LPS only with no skimmer but I do a 1g water change twice a week so all my levels look good. The tank is several years old and corals were doing ok with the PAR38 but not flourishing. I have a goby, a shrimp and cleanup crew.

Right now I have all 4 channels coming on at 10am (30 minute fade to 100% brightness) and Channels B, C & D fading off at 7pm. Channel A (super actinic) fades off at 10pm. The LPS corals are really coming to life but I am getting some algae growth on the glass.

Should I lower the brightness on certain channels during the 9 hour light cycle, or possible waiting to turn on the super actinic later in the day?

I would appreciate any suggestions.
 
From my experience with a evergrow it2040 (165w full spectrum) over my 26 gal the whites are what grow algae.
My lighting schedule is:
(Keep in mind it's set to ramp up and down every 30 min)
Moonlights ramp up at noon from 1%-5% till 2pm when the whites turn on at 1%.
From there, they go to about 15% blue/5% white at 2:30 and up 15% each on to about 5pm when they peak at full intensity.
Then I drop the blue to 65% and keep whites at full till 6pm.
Then ramp blues back up so both are full intensity again at 7pm.
Then ramp down both so whites go off and blue 5% at 10:30pm.
Then ramp blue down so it cuts off at midnight.
All off for 12 hours

My photo period is roughly 6 hours (3pm-9pm). No algae on rocks, have to scrape glass every 4 days or so.

I'm sure what I just wrote made very little sense. lol Soo I'll upload a pic of my lighting schedule later this evening for exact numbers. (I have it all on an excel spreadsheet)

This schedule works pretty good for my tank. Great sps, zoa, and gsp growth and lps are all happy.
