All SPS turn purple

[SmyrnaReefer]

For some reason every SPS I put into my tank turns purple over time. It is a 125g AGA tank with a 12 bulb t5 fixture (6x39W per 3 feet). My parameters are: 9dKh, 440Ca, 78F. It is a mixed reef. Any thoughts?

Do you run carbon? that is the no3 and po4?

How old are the T5s?

Light shock,photo inhibition would be my guess

edit
Woops,I sorry.I thought I read pale not purple.disregard my post.

Brand new in february

How old are the T5s?

no3 less than 10, had LFS test po4 last week and they said it was OK, yes on carbon, but need to replace what i have, its getting old

Do you run carbon? that is the no3 and po4?

i have the actinics coming on at 2:30 and going off at 10:30. the daylights come on at 3 and go of at 10. too much, too short??

Light shock,photo inhibition would be my guess

What does the lfs call ok for po4? Sounds like no3 might be high. How old is the carbon?

I see reds and greens and what not in there.

 

[SmyrnaReefer]

right, but for example, the blueberry stag on the back right of the frag rack in the middle is now solid purple like.. in the pic, you can see light blue and darker tips...now the whole thing is the color of the tips. its growing and polyping but clolr is off..

 

[tibob32]

don't complain, mine all turn either brown or green

 

[SmyrnaReefer]

ok, no more complaining then

Yeah, actually the tank looks like it's coming together quite nicely. You may need to balance out your lighting temperatures. As far as I know coral pigmenation is in large part due to a response in warding off harmful wave lengths of light, just like people tan when exposed to high levels of UV. Perhaps your lights are set up in a way that promotes the creation of purple pigmentation in corals? Just throwing my thought out there...

+1 on lighting tempature. I agree, looks like its coming along pretty well for a new tank.

Yeah I think most of us wouldn't mind if all our acros turned purple. lol Your tank looks good.

Lighting tempature This is a term I havn't heard before. When you say that his lights may be set up in a way that promotes the purple pigmentation, what would, well I guess what I am trying to ask is, what is lighting tempature lol?
