LED Lighting Question

Guys,

I just bought a 165W Full Spectrum LED light and I have a T5 for a 92 gallon Corner Saltwater Reef Tank.
I currently have the lights set up, so the:
Blues turn on at 12 noon and stay on until 11 pm at night.
Full Spectrum and T5's turns on at 5 pm and turn off at 10 pm (looking to change this to turn on at 3 or 4)
I have my sump light turn on at 11pm at night and turn off at 10 am in the morning.

Questions?
Should I leave the blue lights on the whole time my full spectrums are running?

Any suggestions?

I have LPS and SPS coral in the tank with Fish as well.

Thanks in advance

Greetings and welcome

As you know from Krazyones thread I have not yet made the jump from Freshwater to Saltwater yet. But others will be along.

I turn my Blue channel on at 9am at 30% and my whites come on at 10am at 25% the whites go off at 9:30pm and the blues at 11pm I don't run moonlights everything I have read says it is good for corals to have 6-8 hours of darkness to release/use/recharge themselves of the energy they have made from the lights.

Hi, welcome to Fishlore

Assuming your blue lights are 420-460nm, then yes, I'd leave them on with the whites. The UV in the actinic (blue) is what gives corals most of their energy; from most of my reading anyway.

As to timings, my fixture has a sunrise/sunset feature, so my schedule is:
Code:
Channel 07:30   11:30   13:00   18:30   20:30   21:30
   A    0        0     55       55      0       0
   B    0        1     65       65      65      1
Blues are channel B, white is A. Numbers are intensity.

So Blue comes on at 11:30, ramps up to 65% by 1pm, and starts sunset at 20:30, reducing to 1% by 9:30pm. From 9:30pm to 7:30am, it's 1% moonlight, and off for 4 hours.
The whites slowly ramp up from 0 at 11:30 to 55% at 1pm, and fade out by 8:30pm

Thanks guys, I have been reading the treads at this site for a long time now, figured it would be a great time to sign up.
I was looking to buy the light that simulates sunrise through sunset, I should have...
I'm happy with my lights, the coral seems too as well.
Just want to make sure I'm running the LEDs right.
I know when I ran my compact and T5's for a 8 hour period, red algae was a huge issue, despite changing the bulbs. So that's why I'm concerned about running them for more than 8 hours until I can figure out how they do with the 6 hours of full spectrum.
