how long do u lieave your lights on

[Sbdud]

I leave them for 8.5 hrs is that enough

 

[innerspark]

Full power or including ramp?

 

[CoralsAddiction]

That's probably the shortest I'd go with. My lights run for 10 hours a day. Anything above that tends to cause nuisance algae, at least in my tank with Kessil A360W.

10 hrs a day i have a t5 led hybrid

 

[isseym328]

Metal Halides - 9 hours during winter season and 8 hours during summer.

LED's ramp up for 4 hours then t5's come on for 4 hours then led's spend 4 hours ramping back down for a total of 12 hours on my tank.

 

[iSeeMax101]

Lol I have mine on for 6 hours @40% kessil a360we
Need another timer so I can bring my hours up

I have my hydra52's at 12 hours. 3 hours ramp up 6 hours at full power and 3 hours ramp back down.

I have my hydra52's at 12 hours. 3 hours ramp up 6 hours at full power and 3 hours ramp back down.

Is it good to ramp for that long? I'm at 90 minutes. I should try the longer ramp up and down

I have Reefbrites Ramp up from 5% to 40% from 8am to 10am 4 Blue Plus bulbs then come on from 10am to 830PM, My other 4 T5 bulbs come on from 12 to 6pm these bulbs are 2 B+, 1C+, and 1 Figi Pink. My Reefbrites back down from 40% to 5% from 830 to 11pm. Also have 5 Kessils that run all day ramping up and down from 10am to 930 pm. The Kessils fill in the LED pop in the center of tank and give me a daily dose of shimmer.

I have found that my fish spawn and go crazy the last hour before the lights go out as the tank gets very dim. I run a very long cycle because I like to enjoy the tank. The Reefbrite strips with dimmer module on Apex make for true Sunrise to Sunset. An addition I recommend for every tank that runs T5. My XHO strips never run more than 60% unless I am showing off the tank, 60% max for the Kessils as well. I started out dimming the T5 bulbs but found my bulbs did not last that long so when the T5 are on the bulbs are at 100%.

 

[Reefers4U]

9 hours

Other than potentially clowns, what kind of fish spawn in your tank?
Thanks.

 

[pciscott]

Wrasses mostly, Flames, Rose Band, Earlie, and some others, Also have Bartletts that go nuts in these times. The Fish are flashing and acting all that.

Royal blues for 12 hours, whites for 4-6 hours depending on algae or corals.

 

[solitude127]

ReefBrite - 9am(ramp up to 100% at 12) - 9pm (ramp down begins at 8pm)
Dusk/Dawn - 12pm - 8pm
Daylight - 1pm - 730pm

Looks like my schedule is short compared to others. I wonder if my tank would benefit from a longer lighting schedule?

I think you can have the blues on for a really long time, but the whites can cause issues if they're on for too long imo

I dont see why it would be a bad thing.
