Does Corals get as much light in the sea?

[lazybones]

Just a tot.

I was thinking we have got T5s MHs set up for

our tanks for the corals...

But then in the nature.. when the corals are in the

sea, are they also getting so much light?

Cos I was just wondering when I go diving and visiting

corals, usually we bring torches as it is dark in the water.

Any thoughts anyone?

yes. the corals get more light than in the tank

But how? In the sea, under there all dark dark one leh.

Cos I went cairns even the Great Barrier Reef those quite shallow ones

also I see like not very bright leh.

Was just wondering cos I tot in out tanks we use MH and T5s so hot...

Compared to the corals in the nature wouldnt it be a bit "too much"???

Just a thought.

i think its not about brightness....

when the natural sunlight hit the water

surface it break into seven colours...ie rainbow colours

certain colours will reach certain depth....blue will reach the

deepest...and certain corals need certain amout of colours to

survive

and i believe only these MH,t5, FL n PL r able to imitate the natural

sunlight.

i hope i'm rite

if u every think that MH and T5s can replace sunlight, then its a fallacy...

corals that grow near the surface of water are normally more colourful becoz of the light they recieve

Hmm. I see...

Yup. I did noticed(when diving) that those shallow corals are

very nice and colorful.

But those deeper(not so much sunlight) also there were some

which were colorful and luminous ones.

So actually there isn't one light that is sufficient(imitate the sunlight needed)

for the corals?
