A moonlight helps simulate the moon in are tanks. A lot of online pages that sell them say they " Moonlight triggers various internal and external biological activities among the many thousands of reef organisms. Many corals continue to grow under moonlight conditions and some begin the reproductive process" but a lot of people in the fourms say that they are just for us so we can see at night. So why is that?

Well, I could see the bio effect if the lights were on a timed cycle to match the actual cycle of the moon. Lebos timer does this. But, wouldnt it have to match perfectly so as the gravitational effects would match the light cycle>

I don't think They are more then just for our viewing. If it hads to do with gravitational effects, then You don't need them. It will be nature telling the coral what time it is and not the lights.

I dont think they do anything for our tanks more for just our viewing pleasure.......I plan on getting some soon so i can watch my coral bansed shrimp at night. I am getting tired of holding my blue LED flash light every night

the gravitational effect is one aspect of moonlights i have not studied up on. am not sure if corals can sense gravitation changes or not. my gut feeling is no, since there are a bunch of other signals relating to the moon.
please read this thread on moonlights, and tell me what you think?
BTW-moonlight is not blue.

I think if gravity does have an effect it would be in conection with the light and the length of the light period of the moon and maybe have an effect on fish. Its all conected, the light, the tides. Of course this all just pure ramble coming out of my head. Now Ill read the link you posted Geoff!

The moon's gravitational effects have nothing to do with light. The moon pulls the water into an elliptical shape and causes high and low tides. It also causes ocean currents and keeps everything moving.
Moonlight on the other hand would seem like a win-win situation. First you do get to see your animals and enjoy your tank at night. Second how could the light hurt when the moonlight is part of nature. There are also nocturnal marine animals, if you have any, that would probably appreciate the light too.
 Only down side I could see would be replacing more bulbs. LOL
But this is just an opinion.  |

I also want say that by putting moonlights on your tank may not be the best thing for the tank. I have notice that the moonlight that come on some of the light fixtures to be very bright. and by being so is not giving the tank the dark time that it may need. I don't know if it matters or not. Just think it may not be good

gravity may not be the effecting issue but it is tied to the light of the moon as far as its duration and intensity in the cycle of the moon. Caan we say that it has absolutely no effect for sure? The light does have an effect on the breeding of many animals in the ocean. if artificial moonlight was to have any like effect on our tanks wouldnt it stand to reason that taking the step to have the artifical coinside with the real deal would at the least be harmless? I mean fish arre in a realm that each one of their senses is attached to the water. If gravity can rais ethe level of the ocean by many feet, do we knwo that the sensativity of a fish, that may feel vibrations from miles waway, would not pick up some kind of fluctuation?
I/m asking cause I DONT KNOW but nature is far more intricate than any man knows, so why not?

if corals do respond to gravitational changes than having a moonlight that is not in sync with your area could be more harm than good.

Just my point! And Im not saying that they respond the gravitational fluctuations, just that hey may be on some small level, aware of them. Just a thought thats bounced around the attic for a while.

Ukraniun, how do you think that water gets pulled into an eliptical shape?

First off its Ukrainian....that's my nationality not just some name I came up with. You can copy and paste if that helps.
It pulls it that shape because the earth is solid and doesn't change shape and the water bends around it. The attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the earth is also being pulled toward the moon, and away from the water on the far side. This is just what I remember from physics. I'm sure you can find a good book that will better explain it for you. Again this is a simple discussion turning into a drawn out explanation. Isn't this about moonlights for a aquarium????? Or did I miss something motorslave?
