Is too much light bad for coral?

[Rich440]

Like leaving my lights on all day and night?

Corals should only get 8 to 10 hours of light

 

[Rich440]

So more then that will kill em off?

I say 10-12 hours usually. (2 hours of actinics in morning, then all lights, then 2 hours of actinics afternoon). You can always get a timer for your lights if you don't want to manually turn them on/off at the same time every day.

I haves coralife timer which isn't workin out at all

And I'm not at my house much cause I run a business and never home to keep track of the lights so I figured I could just leave all the lights on over night
But if that's not good for the coral I guess they'll have to go close to 12 hours of blue led night lighting until noon or so when I get here to turn the other lights on

You can't keep lights on all day and night. Your fish will go insane and need to rest.

Thx for the help

I'll just have to be there early in the morning to turn lights on
