Lighting suggestion

Hey everyone. I wanted to get some opinions on my lighting schedule. I have a 180g 6ftx2x2 tank with ATI Sunpower 6x80 5ft fixture. I have extra bulbs so open to suggestions one the combination as well. Currently running 4 ATI Blue+, 1 actinic and 1 coral plus. The fixture is set for 2 bulbs(2 blue+ now), 4 bulbs(2 blue, 1 actinic and 1 coral) or all 6 at one time. Currently i have it run 4 bulb for 8 hours and 2 bulb for 2 hours before and after the main 8 hour photo period. I have acros top half of the tank and assorted softies and lps on the bottom and sides. Not as concerned with those as I can move more to the sides where the par will be less. What are your opinions on the lighting schedule? Can I run all 6 for 6-8 hours a day or should I stick with just 4? I have a Seneye and the main rock structure where I have my acros shows about 300. Not entirely sure about the accuracy of the device so was mainly wanting suggestions based off experience than “keep them between 250-350 par” because I have that covered. What I don’t have is any real life experience from people with a similar set up. Does anyone run all 6? Is that too much light? I have plenty of flow with 2 icecap gyres running 0-100 random and 2 jebaos that I have on fast pulse which can pump out 4000gph each. Nutrients are a bit on the low side with nitrates 1 and phosphates running daily between 0-.06. Alk 9, calcium 480, mag 1450 and ph 7.95-8.15. I will also add, this is not a new tank. This is an older picture. Corals are living but not sure if they are thriving yet. Coralline has encrusted everything and my diamond goby is the best sand sifter ever.
Thank you

Welcome to Reef2Reef.
 
I have a 6 bulb ati fixture. I run 4 blue plus for 10 hours a day and the coral plus and aqua blue special for like 3 or 4 hours in the middle of the day.

Awesome thank you. Do you think I would be better to run the 4 bulbs the whole time or 2 bulbs with 4 bulb shorter photoperiod?
 
Corals don’t care much of ramp up lighting periods, their just interested in light, consistent intensity, spectrum and photoperiod. They just want to process. It takes me about 4-5 months, but I push a little more intensity each month and a slightly longer photoperiod. In the end, I have a full spectrum lighting for 10 hours, 1 hour on each end for dawn/dusk, but that’s for me.
Set the period using all lights, but do it slow.
Then never touch them again.
Make sure you swap out your T5’s yearly as they have lost intensity and shifted towards the red during this time.
 
Idk I guess it's your preference I want to get to the point of running all bulbs all day just worried about too much light.
 
Thanks for the reply. I will work my way up to running all 6 for 8. I have 2 bulbs for 12 hours and 4 bulbs for 8. Next step run all 4 bulbs for 10 hours then move over to 4 bulbs for 10 hours and 6 bulbs for 8?
