Torches losing color

[krak256]

I got these 2 torches back in January and they looked like this:

Now a few months later they have darkened, most noticeably in the center:

What caused the color loss? The previous owner kept them under 200 PAR while I am keeping them under ~330 PAR. Is that the reason?

Not sure if nutrients play a role but my nitrates are 2 while po4 is 0.06.

Thanks in advance.

It could be the PAR difference. Are you sure you have enough torches?

Try increasing nitrates 2 too low, I had em at 5-10

More zooxanthellae? Making them darker.
My best guess, seems right.
I'm sure you will get more replies.

Yea I wonder if the higher par increased the zooxanthellae. I’m dialing back my radions to see if that’ll help.

Has anyone else had this happen to their torches?

Did you ever get the color you wanted back?

Not yet. Still the duller color

Could they have been bleached out from the vendor?

I think you have it right. Light and nutrients both play a role in how the coloring of the coral will look.

My torches lost their gold once and I did a PAR test and it was way too low. I bumped up the intensity slowly and the color has come back. IME gold type torches love high par.
