Thanks,some people say that in natural seas, sps grow in shallow water, so they need more white light, is there any basis for this statement?In my experience, white light is purely for your pleasure. 100% not needed

Thanks,my next goal is to learn divingI am a scuba diver and an underwater photographer.
As you descend the longer wavelengths of light get absorbed by the water column. Below 15’, you do not see anything red. You have to take your own light source down there. Orange goes next, followed by yellow and then green. At about 90’, it is a blue world.
That being said, I have seen acropora at 60’. Caribbean elkhorn (another acropora, is found pretty much in shallow water but it is usually deeper than 15’ and more like 25’ and sometimes a bit deeper. And there are other Caribbean SPS corals that are found a fair bit deeper.
Also, what is important to corals is the photosynthetic spectrum. And that is dominated by the blue wavelengths. They do use some of the higher wavelengths but that is not a big deal. I have seen plenty of thriving photosynthetic stoney corals at depth.
Ok,i seenope blue is fine
