Light Cycle
 

Just looking to see what the most popular light cycle is.

I am running:

1 hr blues (dawn)
7hrs Full light
1.5 hrs blues (dusk)

Looking to see what has worked for others.

lights
 

i run 12 on 12 off right now once i finnish doing my new lights it will be 1hr dawn 10 hrs day light 1 hr dusk 24 hrs moon lights

I run my MH for 10 hours and instead of actinics I run 50/50 PCs for dawn and dusk. The PCs are run from the seasonal cycle of my Apex so they run for 1- 11/2 hours before and after the MH.

1.5hrs dawn
8hrs daylight
1.5hrs dusk

3hr dawn
5hr full daylight
2hr dusk
then total darkness....... lol

Just wondering... what are you growing in your tank? Have you noticed any slowing of growth with only 5 hours full spectrum?

I have nothing but SPS in my tank. I am running a 6x54w Ati powermodule and am getting great growth a PE. I read somewhere that sometime less is more when it comes to lighting and I have been very pleased with how my tank has responded to it. I will try to find the article.

1.5 hrs leds 1 hr actinic 11 hrs full lights 1 hr actinic 1 hr leds.

I run a 2hours dawn, 5hours daylight and 2 hours dusk... and I suddenly feel like im not giving my tank enough light reading these numbers...

Dawn/dusk actinic on at 8am, off at 12:00 am. Halides on from 1:30pm to 9:00pm.

3 Hours Moonlight (6am-9am)
3 Hours T5 (9am-12pm)
6 Hours T5 & MH (12pm-6pm)
3 Hours T5 (6pm-9pm)
3 Hours Moonlight (9pm-12am)
6 Hours Total Darkness (12am-6am)

Seems to work well for and gives lots of different viewing modes :)

2 hour dawn, 7 1/2 hour daylight, 1 1/2 dusk with moonlight

cycle
 

still playing with my vortex-plan on dusk and dawn and settings as they would have in indonesia

6 hours full light.

Other..

10am - 22K T5s
1pm - Halides on
8pm - Halides off.
10pm - 22K T5 off.

So I guess that's 3 hours dawn and 2 hours dusk, 7 hours day grow.

I didn't see my choice which is 2 hours morning actinic, 10 hours sunlight and 2 hours evening actinic.

My daily light cycle for winter is 3pm to 3am atinics, which is 2 overdriven t5 @ 80w per with ati blue bulbs, halides kick on at 6pm to 1 am and I am running 2x250w hqi ushio 20k.

For summer the atinics come on at 6pm to 6am halides from 9pm to 3 am and the reason for this is because of heat. I generally run my lights really late aswell because I am at work all day and want to see the tank at night, I tend to run the halides longer in the winter and less in the summer... My tank also gets natural light from a window so that helps...

10am - T5 on
3pm - halides on
8pm - halides off
10pm - T5 off

8:00AM Actinics on
12:00PM MH joins the actinics
8:00PM MH off
9:30PM Actinics off

Actinic on 6:30 am
MH on at 2 pm, off at 8 pm
Actinic off at 10pm
24hr Moon lights

10 am - Actinic + Aquapink on
11 am - Actinic and White on
9 pm - Actinic and white off
10 pm - Actinic and Aquapink off

So 1 hour for dawn and dusk and 10 hours of full spectrum. I like using the Aquapink in my dawn/dusk......seems more like a sunrise/sunset IMO

I see a definite trend here with daylight. It seems most people are at 8 hours or less, myself included. 5+ years ago, a similar poll would typically show 10 to 12 hours of daylight. I think we're seeing a lot nicer tanks now with reduced photoperiods.

My light cycle is forever changing with the daylite hours.. so I don`t have set cycle I have seasons.

10am: 22k T5 on
12pm: Halides on
7pm: Halides off
10pm: T5 off

I run blue LEDs for an hour as dawn then daylight for 10 hours then 2 hours of blue LEDs as dusk

Possible to expand on this?

7am to 8am--actinics for dawn effect
8am to 1pm--off. The way my tank sits I have natural sunlight that comes through
1pm to 7pm --full light
7pm to 9pm--actinics for dusk effect

10am-1pm UVL Super Actinics
11:30am-1pm UVL 454
1pm-7:30pm 150w HQI
7:30pm-9pm UVL 454
7:30pm-10pm UVL Super Actinics
10pm-10am LED's

Dawn at 10:00am pc1, 10:30am pc2, 2:00pm mh1, 2:30pm mh2, 3:00pm mh3, till 7:59pm full daylight, 8:00pm mh1 off, 8:30pm mh2 off, 9:00pm mh3 off, 10:30pm pc1 off at the same time sump refugium light on, 11:00pm pc2 off, led night light is always on.

I didn't see anybody mention adapting for the lunar cycle.
Is anyone doing that?

I have the illumina so I have 3 hour sunrise 7 hours of day light 3 hour sunset then the lunar cycle for night time. Im thinking of cutting down my day duration as it maybe a little long. I also have 6 cloud periods a day with a 5% chance of lightning! :lol:

how do you do your clouds-haven't figured it out yet-as you know the damn light doesn't come with instructions
