I think this would be a good experiment- instead of defending thoughts without research or facts. I bet some corals might continue to grow under limited lighting but stable chemical levels in the water. The corals might lose color but after all the polyps that make up a coral are animals and if they have food and everything else- they can adapt over time.

the ideas presented in this thread is the reason why George Bush was elected and Sara Palin has a shot.
Ninja *** are you talking about? spontanious evolution in a tank?
lets end this stupid debate right now all corals that have zooxanthellae will DIE if keept in the dark for a month. now Stop it. I mean there must be a reason why they have zooxanthellae within their tissue right? ohh yea it's to produce simple shugars from photosynthesis that account for more than half of the food used by the coral !!!!!.

No but seriously I think lighting is very important b/c when I was researching and reading in the beginning it was amongst the first factors to coral growth. I just like to hear people out and although I wouldn't try it myself, Im sure there are corals that can survive (not thrive but perhaps survive without intense lighting). Spongy corals have been found in VERY (800 meters) deep oceans and how do you explain their lighting source? Just saying that I don't think this is a bad topic.
That is the thing right there. The subject is GROWTH not sustain or hanging on by a single zooxanthlae lol. Those 30 days of storms still have light getting thru though not as much but the UV rays on the other hand keep bouncing between the earth and the clouds plus the ocean has so much more micro organisms for the corals to feed off of to help to survive those stormy times. That 10" of growth per year would probably be 12" per year if there werer not long periods of clouds.
As for those sponges at those depths they tend to be non-photosynthetic sponges.

Great point Evsalty- if anyone wants to lose their lights, I can hold on to them while you experiment

Is this really a debate on wether or not we need strong lighting(if any) for SPS?
Nice seein' ya around this part of the woods Robert! :beer:

You too Justin. I Hope NY is treating you well.
I think the peace has been kept really well. Many threads like this get to name calling and such very fast and you and I have not done anything like that.
With that said I say again why not try thirty days off on your tank and then we shall see how much growth that same coral had.
Im saying this because I can see some people here causing a problem
Here you guys go please read ..

Is It Necessary to Provide Maximal Illumination?
No. Common sense and a quick look at reef aquaria proves that most photosynthetic invertebrates will thrive under conditions of relatively little light. There is no evidence that I am aware of that suggests corals' zooxanthellae require supersaturating light intensities in order to maintain growth rates and/or provide proper nutriment to the coral animal. Most 'common' corals saturate (that is, photosynthesis is at a maximum rate) at light intensities ranging from 200 to 450 molm²sec.
Can I Increase the Photoperiod and Provide Less Light in Order to Maintain 'Natural' Light Dosage?
Existing evidence suggests that extended photoperiods, or worse, non-stop illumination should be avoided (this should not be construed to mean cycles mimicking daylight and weak moonlight are to be resisted).
Done mostly for my own amusement, Table 2shows the PAR values required to simulate Spring and Fall DLIs of shallow water corals in Hawaii. DLIs are listed at the far left. Scroll down from Hours of Illumination (at top) to determine the PAR values (in molm2sec) required to deliver either the Spring or Fall DLI. Italicized fields designate levels warning of over-illumination of the most light-tolerant corals (Pocillopora meandrina, Porites lobata, and various Acropora spp.). Bolded highlighting warns of an excessive photoperiod, possibly resulting in disruption of zooxanthellae reproductive cycles. Note that some low-light corals will bleach under these light intensities!

Hey Batt thanks on the reading, but you should re-read the entire online article again and not take bits and pieces.
PROLONGED LIGHT PERIODS....(bad for corals), another keyword to look for NATURAL LIGHT DOSAGE..
NO where in the article does it mention less than 12 hours of NATURAL SUNLIGHT your
corals will thrive.
If you look closely at the graphs.. reproduction takes place during the dark stages...
I believe there is where you may associate what you are refering to for growth.
As in plants... this is where growth takes place. The plant cell cycle.
Remember we are trying to replicate the NATURAL environment to sustain life... in an enclosed glass box(as they said in the article), alot of factors need to play into this.
As someone mentioned earlier stability, coral feedings, dosings, wc's, etc etc... all help promote growth. Also the 12/12 cycle.
This is what I got from your article... something we all took in 5th grade sci when the teacher gave us some beans to grow... anyone remember that?:wavehand:
