    Guys I really need help regarding the amount of time my lights are on and what steps do I need to follow.

    I have the New Boyu with the LED's in. 3 x Blue and 17 x White. Because of the lights being on a timer all LED's come on at once and goes of at once. The time the lights are on is from 06H00 to 19h00. I know this is to long.

    This is my idee but I need help and advice.

    Split the blues and white and run them on seperate timer.
    Run blue 06h00 - 11h00
    Run blue & white 11h00 - 18h00
    Run blue 18h00 to 19h30

    Will this be okay?

    And then advice as to just cut down to the new times or bring them down slowly?

    to be honest, the answer is what ever suits you.

    my tank comes on after 12pm as i am not home and turns off after 9pm, @carlosdeandrade starts early, i think 5am and turns off 6pm, it all depends on what time you are able to view your tank...

    weekends my tank is on from 6am till 9pm ...
    but no less then 6-8hrs per day

    I feed in the morning and the spot where the tank is in the house is very dark so some fishes are still asleep if the main lights don't come on.

    I have two vertex illumilux lights on timers that just turn them on and off (no diming). I have the time that they come on and off staggered so one comes on at 6:30am and off at 6:00pm and the other comes on at 7:00am and off at 6:30pm. By that time all wrasses are in the sand, clowns are huddling in their fave corner, tang is behind his rock and Jester Goby and snails are srating to explore.

    No issue with anything ... no coral bleaching, etc

    in my opinion it's not for how long you run the lights but rather at what intensity and what color spectrum.... most coral reefs are located (according to what I've been reading) at a depth of about 15 meters. at such depth only the blue spectrum of light is able to penetrate where white and other colors stop much higher.. so in my opinion blue is preferable color to corals.. now as to how long to keep the light on.. I think if we look at corals that come from regions near the equator they are used to long daylight periods... I believe most of the corals we keep are native to tropical waters e.g.. near the equator. I'm not aware of people on this forum that keep cold water tanks

    I have changed my settings as follows.

    06h00 - 10h00 all lights on
    10h00 - 15h00 no lights only ambient light
    15h00 - 20h00 all lights

    have not split the circuit on blue and whites on the TL-550.

    Please advise if this will be okay or must I leave it as is?

    Corals I have:

    Green Birds nest
    Zoas
    Kenya Tree
    Galaxy/Tooth Coral
    Green Button Polyps
    Star burst Polyp
    Zenia's
    Montipora Red_Orange

    IMO Just leave the lights on all day. My fish looked confused when my lights went off during the day. In nature that does not happen. I have the same corals as you and I run some serious lights on my tank. My corals and fish are happy as.

    Most of the guys on this forum run the lights all day.

    I would keep it simple really, plan to run your lights between 8 and 12 hours a day, have them on at a convenient time when you are at home to enjoy the tank.

    If it works for you then it works. My lights are also on 13hrs a day. In the beginning I thought it was causing huge algae growth. But once my tank cycled there is very little algae and my fish even know when its time for the lights to go off. They all start taking up there little spots in the tank. Give your fish a routine and they will get used to it.

    Nothing wrong with that. If you look at some of the places that most of our fish and corals come from, their daylight hours average between 10 and 14 hours a day, taking into account dawn and dusk. So you're all good. :thumbup1:

    Thanks guys, I was just confused because my logical thinking also tells me that the places where the fish comes from have longer day hours. But I was informed my a sponsor LFS that my lights are on for to long. They told me no more than 8 hours. :( Thanks for all the input, advice and help.

    They're not wrong, 8 hours is also fine, a lot of people run their tanks for only 8 hours a day, it saves on heat, electricity costs and often helps to stunt algae growth too. :)

    there is no right or wrong answer as i and others have said...
    if anything it would just throw the fish out a bit, but corals do need some dark time to complete the photosynthesis cycle.
    i have recently moved my light cycle to 6am - 9pm going from dawn - full power - dusk with 2 hour moonlight and have had my corals grow and change to deeper colours in 2 weeks

    Okay then I am just going to split my white & blue lights so that I could also do a dusk and dawn setting.

    Perfect, have the blues come on maybe an hour or so before the whites, then when the whites go off at night let the blues stay on for another hour or so.
