Too much light?

[Paulb89]

A few of my pieces have gone pale in certain spots, no loss of flesh but they seem to have lost pigmentation.

Would this be due to too much light?

Or does anyone else have any idea on what could cause it?

You really have not provided enough information to even make a guess :)

How old is the tank?
How long have you had the coral in question... Are they new?
Full tank picture under white light would provide a lot of info.

What are the measured water parameters?

The tank is 6 years old

2 of the pieces are about a year old and we're wild collected.

The other blue stag is from another tank, also over a year ago but was a fully established piece.

Alk 7.5
Phosphate 0.1
Nitrate 10
Calcium 470
Magnesium 1350

ICP always come back fine.

Those pictures were under white light, the tank is lit by 2 orphek icon Atlantics and 4 T5 coral plus bulbs.

Okay thanks.

If flow has not changed and salinity has not drifted too far, I'm thinking about water changes / trace elements additions.

Nothing else leaps to mind.

It gets a weekly water change of 10 percent every week and runs the red sea trace colour programme
