    when I switch of my pharaoh 250w led, the blue lights stay on. Is it okay if they stay on all night ?

    I have my moon lights running on a cycle. Some nights it is full moon lights and then it fades to no moon lights. I have my intensity set very dim, if I leave them on normal mode then I feel I have too much light in the tank which in turn has the fish more active after lights out, which I believe is not a good thing because it can lead to stress. I believe moon lights should not have a high lighting intensity, you should barely be able to make out what is going on in your tank (well that's how I see it).

    Yeah i run my blue lights on 1% intensity at night (can bearly see anything inside), but they do switch off at night for about 8hrs before coming on again. Also not sure what the exact rule is about lights during the night.

    My led time chip is broken, so i cant set it. Haver to switch light of and on manually with remote. Because of this, I cannot set the intensity of moonlights, but they seem quite bright to me.

    I have had my tank in total darkness a good few times, so far no issues. They all seem to enjoy the peace. I started leaving the moonlights onn again, think I am gonna start switching them off. With the lights onn, the Sailfin stays awake.

    a total "dark period" is important for corals as they need a rest period.

    However, naturally a reef has lots of moonlight at night , I think faint blue lights should be okay, mine are quite bright though.

    I think low intensity is fine, can't set mine lower and they are very bright. Just going to switch light of at night.
