Are my moon lights too bright?

[murphy01]

I have three Reefradiance led lights on my 180 and the moon lights are constantly on. Seems like my fish never sleep. Is there too much light and can this harm them.

Ive never moon lights but i am a big believer that the fish/coral need at least 8 hrs of complete darkness

Hmmm. Some have disappeared lately too.

yea moon lights are cool when looking at the tank at night but just have them go off when you go to bed or not gonna be looking at the tank. I have an all in one system where the sump is built on the back of the tank so my refugium light leaks some light into the DT after the main lights go off. But the refug light goes out at midnight and tank is complete darkness until 9 am when refug light comes back on and regular lights from 10 to 9. So from 12am to 9am my tank is not lit by anything
