Are all blue lights OK?

[DannyBCorals]

So I'm setting up a frag tank, and don’t plan on adding too many fish, only fish to clean frags, and control copepod population, but I have a question, if blue light is on 24/7 or just for 8 hours a day, what would happen!

 

[TheShrimpNibbler]

Leaving the lights on all day might mess up your pH. I’m not sure how it would affect coral growth, but fish need sleep.

 

[MERKEY]

If light isn't in the 420-460nm no growth but I dont think I'll effects.

As long as its moonlight effect for a certain period that would consider as "no light" and would let fish "sleep". I believe.....could be wrong lol

What does nm mean?

 

[The Aquatic Arsenal]

Some corals do require the red, green, and white spectrum's to grow. Have you seen the AB+ schedule?

 

[TheShrimpNibbler]

What does nm mean?

Nanometers. It’s the wavelength of light

 

[MERKEY]

What does nm mean?

Sorry its nanometers and how light is measured...

Basically with no light or not in those spectrum readings no coral growth.

This is a great place to start.

What’s the AB+ schedule? I’m using the ultra colors premade schedule by ecotech

NO! All blue light and no white light will screw up your corals. It forces the zooxantheallae to make too much oxygen and it is highly unlikely any of your corals will be able to deal with the resulting free radicals for any length of time.

How come Reef stores have blue lights on always though? That’s what I’m puzzled about

 

[MERKEY]

I will try to post this thread....it is this conversation. I'm bad with computer stuff

 

[MERKEY]

It's called
"Effects of using only blue LEDS"

I guarantee you they don't. The whites are probably on while the store is closed.

Nah ocean state aquatics doesn’t

Here's a link to the thread Merkey refferenced: Effects of using only blue LEDS

To update my statements in this thread there are corals that grow deep enough they only see the blue spectrum refferenced in this thread. Sadly, since then I have seen people kill corals running only intense blue light. Corals that will do well with just blue light do not want the intensity they are likely to be subjected too in most aquariums. Another probelm is no data was given on what species did ok, what was the growth rate and what was the long term survival rate, was it a few months or was it several years?

Unfortunately consumers have been trained to look for "pop" and pet shops have to sell corals. They're not worried about the long term effects on a corals calcification or photobiology.

Thank you!

Riddle me this....

We all agree Jason Fox is a multimillionaire selling Signature Corals.

He is now promoting what's labeled as the "JF METHOD" of growing signature corals under all blues btwn 400nm to 500nm....no whitelight....

which btw the way, white light is the entire visible light spectrum coming g into your eyes all at the same time, blues, greens, yellows, oranges and reds..... makes up white light

I have been doing some DEEP research all of 2019. I have modified my Blacksboxes by resouldering a combo of 400nm, 420nm, 440nm, 460nm and green 520nm diodes. I'm pretty happy.

Im seeing really good growth BUT my tank us a special zoas/paly only tank.

@Timfish I'm open minded. I would like to see links explaining "too much oxygen " to actual lab testing, actual lab results.
