Sunlight Nutrients

__________________________________________________ __________________________

Thesis;

I think that photosynthesis is actually the conversion of sunlight energy
into chlorophyl. Corals use sunlight for energy, but do they
photosynthesize or just recieve other nutrients from the sun, if so, how so.
I assume they get some kind of nutrition from light energy radiation in the
proper spectrum as humans and animals get vitaminD from sunlight. Can
vitaminD and other nutrients possibly penetrate water, and if so, what other
nutrients come from the sunlight?

Question;

What kind of Nutrients do ocean animals get from sunlight. Vicki has posed
a wonderful question/idea. Regarding Kelvin Temp penetrating certain depths
of the ocean what nutrients flow to what depths from the light and energy of
the sun, and how does this benefit the organism?

Answers to come up with using above guidelines should be ;

What Kelvin temperatures are best for what depth
What Kelvin temperatures are best for hard corals as a whole(average)
What Kelvin temps are best suites for underwater plants as a whole
What Kelvin temps are best for soft corals as a whole

Note;

Do not worry about wattage, which in turn is converted to Lumens. Keep this
interest clear where possible in this study.

Do not worry about NO vs. Halide in this study where possible.

opinions are important, please reply using original post.

No.....photosynthesis is the conversion of sunlight into energy BY
chlorophyll. The chlorophyl does the conversion.

(chlorophyl is tiny cells in plants which convert sunlight to energy.
It is what gives the plant its green colour. There are other pigments
like keroteen and so on which is the oranges and so forth. Without
sunlight the plant looses its chlorophyl and turns white. Some plants
like mushrooms don't use it and get all there nutrition from soil. In a
month or so we here in the northern hemisphere will be watching our
leaves turn colour which is nothing more than chlorophyll dying off and
the other pigments popping out as orange, reds and yellows)

( I have been doing some reading and the only thing I can come up with
is that corals must photosynthasize. It may be that they have a
symbiotic relationship with some form of algae. I don't know. I have
also read that some of them don't and have to be specially fed in order
to thrive. My only hypothesis would be that the coral found in deeper
water developed were sunlight loving algae could not live and they
learned to survive without them)

Chlorophyl uses sunlight to produce sugars - plants use the sugars for
energy.


Do corals even HAVE chlorophyl?

(sunlight in moderation, stimulates our own bodies to produce VtD. We
do not get it from the sun)

Huh??

Light contains no vitamins. It may cause some chemical reactions in
certain things that may cause those things to produce certain compounds,
but sunlight contains no vitamins in, and of, itself.

Absolutely none. It's all about spurring chemical reactions. That is the
ONLY role sunlight plays in nutrition.

As I said I really do not know anything about corals, but I do know
plants. It will be very interesting and I should get a lot out of this
thread. So folks with knowledge on this subject please pipe in.

Vicki

yes of course, how stupid of me to think nutrients pass thru water from
light, its the energy from the light that is converted in a reaction.
I will reiterate the "HUH" question.
What kind of reactions take place in coral using sunlight as the energy
source. Is there anybody here that knows this?
What kelvin temp is best to grow plants in the refugium
What kelvin temp range is best for soft corals, without assuming that it is
the same as for hard corals.

plenty here do most wont answer you , I think this Q gets answered below

What kelvin temp is best to grow plants in the refugium

first off, color temp not "kelvin temp", kelvin is a measurement of temperature otherwise
you would be saying temp temp and it doesnt work. secondly just about any color temp will
work nicely in a refugium. it depends more or less just like the answer to the next
question for what, a refugium doesnt require any light at all, if all you want is pods,
add a specific macroalgae or plant and you up the requirements.

What kelvin temp range is best for soft corals, without assuming that it is
the same as for hard corals.

again why do you assume its different for hard corals than in soft corals ??
and any answer is coral dependant, though the chlorophyll in the zoothiline(sp?) (for a
non text book definition, algae that grows in the coral) will adapt to many different
color temp levels, even through out the same piece of coral, as some parts will be shaded
others will be in direct sunlight all day, and others only in the morning or evening.
certain corals will be found at deeper depths and will be aclimated to a color at the blue
end of the spectrum, others will be collected at very shallow areas and will be used to
the yellow or white end. in the end we as reefers must adjust our spectrum so that algae
doesnt grow faster than the corals this all but demands no red or yellow spectrum
lighting, there is also an apearance end I myself like the blue end and run 20,000K bulbs
.

Hi,

waht's a refugium (of course I can guess from the name also what're
pods ?

Thanks,

Hmm, kinduva trick question Corals themselves to not photosynthesize as I
understand it as they are animals or colonies of animals. Within their their
tissues lives "supplemetary" algae known as zooxanthellae. It is within these
algae that photosynthesis takes place and produces sugars as a by-products
which the corals then consume.
Obviously not all corals will contain these zooxanthellae - these animals will
(mostly) be filter feeders of phytoplankton, zooplankton, and will uptake
nutrients directly from the water. Those that do contain zooxanthellae can
usually get sugars from the algae, nutrients from the water, and
phyto-/zooplankton - this is what the tentacles/nematocysts are for. AFAIK
there is still some debate as to exactly where coloration comes into play -
there are those which maintain that it (coloration) is to filter certain colors
of light while others believe it's a simple by-product of the tissue.

I assume they get some kind of nutrition from light energy radiation in
the
proper spectrum as humans and animals get vitaminD from sunlight.


Again, as I understand it, Vit D is made by enzymic reations due to light not
from the radiation itself. I'm sure there are others that can further explain
this much better.

What Kelvin temperatures are best for what depth
What Kelvin temperatures are best for hard corals as a whole(average)
What Kelvin temps are best suites for underwater plants as a whole
What Kelvin temps are best for soft corals as a whole

What we are (IMHO) trying to do is to simulate sunlight without going into
extremes into certain temps under which the "unwanted" algae will thrive.
Corals themselves will be fine under far more Kelvin temps than we use probably
down to the 2500-3500 range but these "unwanted" algae will as well - possibly
smothering the corals and starving the zooxanthellae of the light they need.
So we get the light color up to take care of this problem as well as simulate
deeper water as much as possible by using the higher end of the visible
spectrum. All this while still trying to make the whole thing pleasing to the
eye and/or pocketbook.

Of course - it's all debateable and I'm hopeful someone will set me straight
if I'm mistaken.

Question;

I recommend you get your hands on a copy of "Aquarium Corals" by Eric
Bornrman if you seek detailed info.

What kind of Nutrients do ocean animals get from sunlight.

None. Sun light provides just that, light, not nutrients. The nutrients
comes from the zooxanthellae that lives within some corals are respondable
for converting light energy into food sources.

Answers to come up with using above guidelines should be ;

What Kelvin temperatures are best for what depth
What Kelvin temperatures are best for hard corals as a whole(average)
What Kelvin temps are best suites for underwater plants as a whole
What Kelvin temps are best for soft corals as a whole

All of the above are meaningless guidelines as each coral have their
individual needs. To summarize them as "a whole" is as bad as trying to find
"what is the best fuel for all automobiles".

One needs to have the proper setup for the livestock they wish to keep, and
make the proper corals selection based on that enviornment the keeper has
set up.

Do not worry about wattage, which in turn is converted to Lumens. Keep
this
interest clear where possible in this study.

Do not worry about NO vs. Halide in this study where possible.

opinions are important, please reply using original post.

This isnt going to be much of a study as it is too open to draw any
conclusion with.
