Do SPS corals benefit from sleep mode?

[jonnybravo22]

i am currently using night mode, but only to lower the noise from the MP40 so i can sleep. i always thought that was the intended purpose.

i have been around the ocean many ,many times and it is usually calmer at night . the sun goes down and then the temperature evens out and there is less wind ,thus calmer seas

I too have "been around the ocean many, many times" in fact i have been in and around the ocean my entire life.

to a point you are correct, the surface of coastal or near shore waters often calms down at night. But that isnt the wind that really forms waves and currents. the winds that cause waves and currents are seasonal open ocean winds that tend not to calm down at night. this is why waves break all night long and not only when it is windy.

it makes sense if you think about ocean climate on a global scale.
-Wind is created by a difference in climate pressure (low pressure system vs. high pressure system)
-The largest contributing factor to these pressure differences is temperature differences. (gross simplification) but basically temp rise in one area creates high pressure because hot air rises--the air rising kinda creates a vacuum or pressure system that sucks air out of the cold/ low pressure areas. Hence air rushing from one area to the other--wind.

In coastal regions the quickest temp change happens on land not at sea, so the wind in coastal areas tends to blow onshore during the day and be still or blow offshore during the mornings and evenings. these are also the times when there is the greatest overall change in temperatures.

Now what about the open ocean? well the seasonal winds that create real waves is caused by global temperature differences, as in the difference in temp between the hottest and coldest places on earth (Arctic oceans vs. the tropical oceans) both of these masses tend to have seasonal variations in temp and wind rather than daily variations.

I posted about this a while back and got slammed for saying the ocean is calmer at night since the energy from the sun is absent.

Be that as it may, after a lifetime of boating on coastal waters and the open ocean, including 4 years on a USN frigate that steamed 10 out of 12 months a year and numerous trips from Florida to the Abacos, Bahamas in my 35 ft sportfish ...
I STILL think the ocean is calmer at night, not always, but mostly.

I run 3 mp40s on my 180 sps in 100% lagoon mode, not synced 24/7.

So there .:wavehand:

heres a subject that i have not seen discussed on the same line of if they have a sleep mode . do corals grow faster if they are on a 24/7/365 light ON mode ? many plants do not need darkness except to flower and seed etc and grow much faster if they have constant light .what about corals ?

over exposure to light = bleached corals!

well, it's a fact that the sun, wind, and evaporation, and etc. cause much more............................versus the night when the oceans are absolutely calmer...:fun2:
