pagoda cup coral

[fishgirljockey]

These spots just showed today on my cup coral? I am not sure what it is if someone can please let me know what it is and what I need to do!!

all levels are normal. I use the corallife light.
Only problem I have been having is I can’t get my phosphates and nitrates up a bit; they remain at zero.

i did have an anemone die recently, two days ago so maybe this can be the result from that? I had a rock fall on the anemone and after that, it declined rapidly.
Other than that, everything else is perfect. Fish are great. Other corals are out and doing well. I have a few Zoas, two Duncan’s, some mushroom corals (rhodactis and a ricordea) clove coral and a Jack-o-lantern leptoseris.

Very hard to tell due to heavy blue lighting
White lighting best

My phone makes it seem like it’s heavy but it’s not. It’s 70/30 (white 30%). Corals actually do way better the more blue you have. I have a blue background so it makes it seem super blue. In person it’s just a tint of blue.

Do Corals Need White Light To Grow in Your Reef Tank?

As with most of the creatures in your reef tank, corals need light. Their growth depends on the intensity and the spectrum (color) of the light. What about white light — do corals need them

My growth and health has increased over 50% putting more blue.

Actually coral adapt and change to the color of the lighting they're grown under. The zoanthxelle actually does this process and is a beneficial plant cell that photosynthesis in the coral skin.
This is why coral can brown out or bleach. As well as water conditions can effect this yes. I am one of the rare reefers that prefers a more white light than a blue light and the coral glowing unDer actinic light. Looks fake to me.

The reason ur coral grows better under the blues is probably cause the seller grew them under blues as well.

I have heard that corals will show some colors only under whiter lighting. An example is the yellow in porites. Also, I think he means to change the light spectrum to a whiter light when you take the picture.

@monkeyCmonkeyDo

you can laugh all you want but this coral was nearly dead TWO WEEKS AGO. Now it looks like this. Doesn’t look so blue does it? As I said, my background has blue, it makes the tank seem like it’s more blue than it really is. You can see the blue background in the cup coral image. Depending on the angle I take, the iPhone makes it extremely blue. Look at the other photo of the cup coral from a different angle. This phone sucks

No the seller uses white

The blue light spectrum, not white, is what corals need for optimum growth. It helps stimulate coral reef calcification, which is the primary measure of growth. In this process, the corals lay down the foundations of their calcium-rich skeletons.

According to a study, blue light also helps increase the number of Zooxanthellae in corals. It helps boost Chlorophyll A levels in these algae as well.

For one, Chlorophyll A can only absorb wavelengths ranging from 440 nm to 675 nm. Blue light, with its shorter waves, only has a wavelength of 450 to 495 nm. Indeed, it’s a perfect fit for the photosynthetic needs of Chlorophyll A.

Lol. They're I laughed more.

I wasn't trying to be disrespectful. Carry on.

All good. Just saying

This got really off the rails guys. I think vetteguy was just saying white light is best for pics to identify problems

I am not saying that bluer light doesn’t make corals grow faster; it’s probably true that corals will grow faster under blue light. I’m just saying that corals will show different colors under different lighting. Some pigments, especially non fluorescent ones, will only be seen under white lights.

This study was using red versus blue light anyhow. Personally, I definitely experienced much faster coral growth running higher whites than just blues alone. Except for deep water acros.

I use about 80% blue and 20% white all day. I don’t switch the lights throughout the day. The lights go on at 11am and off at 10:30pm. I know some people do whites part of the day and then blues. I stick to one and just have noticed huge difference running more blues than whites. When I started I used more white, sometimes zero blue. I was getting results but not the results I get now running more blues. Most places you buy frags are in darker blue settings.

U asked for help and @vetteguy53081 was asking for a pic under white lighting to help u w the spots. Don’t think it was meant to b a debate about spectrum and what’s best for corals for their metabolic needs

 

[fishgirljockey]

Yes I read his response wrong. The spots went away. It was like someone lit out a cigarette on the coral. It was about 3-4 dark small circle spots on it for a few days. Hasn’t returned tho since. Weird
