How long to run my lights?

[Dwb5]

Ok so I was looking at my tank today and got to thinking about my timers on my lights.I have a 6 bulb T5 ATI fixture. My actinics come at 2:30 then the rest come on at 3:30 then my main lights go off at 9:00 and the actinics go off at 10:00. How and how long does everyone else run there lights? And what are the pros and cons to a longer or shorter times? I'm looking forward to see your answers.

I aim for something as close to "natural" as possible. When none of my lights are on, i let natural sunlight fill the room to the tank to help "ramp up" and "ramp down" since I don't have a dimmable fixture. You need to find a sweet spot, enough light to grow your corals, but not too much that you bleach them or see excessive algae growth.

48 inch ATI 6 bulb T5
1 Actinic Blue and 1 Purple Plus: 8:00 am - 8:00 pm
2 Actinic Blue, 1 Purple Plus, 1 Coral Plus: 930 am - 6:00 pm

That makes alot of sense.I also like your bulb combo. Do you get good growth and color?

 

[CodyRVA]

I think so yea, i had no name junk bulbs in there at first because i bought the fixture used. The color I get now is amazing, good growth as well. Can't go wrong with ATI.

 

[Dwb5]

That's the way I feel. I have 2 purple 1 actinic 3 blue plus. Still trying to find what I like. My try your combo.

That don't seem like a lot of light for coral growth. My attinics come on at 10 to 10 while my halides come on at 12 and 1 to 5 and 6 so it's 12 hrs of attinics t5 and 5 hrs of halides

 

[Dwb5]

Well that's why I was asking the question. I was thinking if I left mine on a little longer it would help with color and growth

My H52's start to ramp up at 7am off by 7pm my 4x54w ati at 12noon 1 KZ SUPERBLUE , KZ FIJI PURPLE 12:30 ATI BLUE PLUS , purple plus.
All t5's off at 9:30pm.

 

[Dwb5]

So will running them longer help give them color up more?

 

[Greenstreet.1]

That is not determined by just lights nutrients are involved also light is just part of the puzzle Imo

 

[Dwb5]

Yeah that's what I'm trying to learn now. I have been trying to keep a better track of my water chemistry to help out as well. Just wanting to make sure that my lighting is up to par as well.

Take your time keep things stable and it should all fall into place

I also have 2 Hydra 52 HD's. My actinics Royal blue (Actinic's) come on at 8am, All other led's come on at 9 ramp up 2 hours. From 11am-7pm they are at peak, ramp down 2 hours. 9pm- 10pm are just royal blue (actinics)

7-8 hours is what has always worked for me. Good luck getting it dialed in! Remember to go slow with any adjustments on your photoperiod.

I have an Orbit Marine LED system and two Ecoxotic Stunner Strips in a hood covered with metallic tape on the inside.
I like to see my corals in the evening, so I shift my photoperiod.

Blues ramp up at 12 for 30 minutes. White ramp up at 12:30 for thirty minutes. Ecoxotics are not on a dimmer so they come on for 4 hours (2-6 pm) for the most intense part of the day. Then I reverse the process and have 2 hours of 'moonlight' with the blues at the end of the day.

I programmed my light to come on right just before i get home from work which is right around 7:00pm. It turns off at around 3:00am.
Good for corals and good for the house and good for my life.
