palythoas polyps getting [stained] please help!

[muddy tdi]

I have found these polyps (stained) today! Is this ok? My parameters are all fine except some higher calcium and magnesium. Anyone can give me advice on this if it is an issue. I have bought these palys around 3 months ago and they were doing fine like the other lps that I have.

what do you mean by stained? they look like normal mind blowing paly's

this is how normally looks without any dark marks. Only today I found these dark marks on the polyps and I don't know if it is safe! Sorry about my bad image rotation on my first pic. You can easily see the difference of the polyp colour, today I spotted these marks and have no idea if it's ok or not. Anyone experienced this?

They look normal to me.. They might just be coloring up, a good sign

Thanks, i have found that too much light was the problem. I lowered them around six inches and came back to normal.
