Moonlights in a reef

[marcingo]

Hey everyone. What do you guys think about a moonlight in a reef tank. Are they necessary. From what I have read they have both positives and negatives. Supposedly is you keep moonlights and your tank doesnt get any complete darkness your fish can go blind but people also say moon lights help with coral propagation. Just wanted to know everyones opinion on this.

I think it's a nice feature but not needed/essential to keeping a reef.

Personally I think if someone is going to put moonlight over the tank, it's more important to correctly simulate the moon phases (varying intensities over a 28 -29 day cycle) plus trying to get a close to accurate moonrise/moonset times, otherwise it's just a "night light."

I've never bothered with moonlights myself. I once came close to inheriting a cool little LED based moonlight but I declined on the basis that I wasn't sure how to control it.

Of course now I have a Tunze controller that does do some kind of moon simulation but I haven't looked into what it would involve to get something going.

I use a moonlight but its only for aesthetic purposes. It comes on when the other lights go off.

I have been thinking of hooking up moon lights for a long time. Do you leave them on all night or just for a period? What intencity are the desired moon lights?

[Quagmire]

I have moonlights,but only use them on weekends when I'm up late.I think if you have them on all nite,that it stresses the corals under them.Sort of like never getting any sleep cause that damn light's on.

I've always had some kind of a light on in my fishroom. Now I have tiny moonlights over my reef tank. It's never totally dark outdoors. My Discus used to be totally freaked out if there was no light at all.
