SPS dramatic color change

[takayan]

My pink birdnest changed the color completely. I kept the pink color for more than 2 years, but the color was totally changed to green.

Before

After

 

[Vapour1ze]

Mine did the same exact thing. Following. Lol

 

[ZorroV]

I have the same coral and it was never pink. Looks just like your "after" picture. Just out of curiosity, did you change bulbs if you use bulbs as lighting or increase the intensity of the lighting if you use LED's?

 

[SoloGarth]

Wow haha. Yeah I think I have the same birds nest but it has always been green.

 

[karimwassef]

I have the same, but mine started green and turned pink...

I think it's a reaction to UV. The tank I got it from has very soft LED lit - bright, but not intense. Not sure if that makes sense.

My tank is MH heavy with extra UV - both with a double ended MH 400W and additional UV LEDs (300W).

Basically, I think it's "tanning".

I think mine is the same coral. Perhaps not. But I keep mine under LEDs no UV and it has always been green.

Sorry I just saw that yours started green and turned pink. So mine backs that up. I bought the original drag from an led lit tank. I have to admit I like the pink better.

 

[karimwassef]

I wish I could keep both colors in the same tank. Love the contrast.

So it might be trace minerals doing this. Here's a great link that will hopefully help:

Link doesn't work? On my iPhone at least.

Oh god not that article again. I think that this article is a serious over simplification of a very complex concept that is not based in anything other than anecdotal opinions. Just my opinion.

Looks like the site is blocked? I found this one that matches the link end

I added spaces to make it go just in case.

[karimwassef]

Have there been any studies?

I don't supplement K or I. I do feed coral food like reef chilli, etc...

 

[SoloGarth]

Huh. So blocked by reef central? That's funny. It just basically details how each coral color is dependent on just one particular element and that you should dose your tank by looking at the coral colors. Sort of a recipe for disaster.

 

[karimwassef]

It seems like it's pushing 'color supplements' as the answer and I'm not convinced. I think it's light mostly and then the availability of nutrients to color up.

No studies that I have heard of. There have been scientific explanations of what colors are caused by certain pigments/fluorescent compounds in coral magazine. It was from a while back but I have it somewhere here. It says nothing about dosing K for reds I know that.

IME, High placement under halide lighting brings out the pink.

 

[karimwassef]

I agree tmz.

Do you think it's the higher intensity UV content?
