sps corals losing color

[ttran1130]

I have a pink bird nest frag. When I got it, it was pink but now it looks brown. My lighting is 3x250 mh. My question is will the color come back? Is my lights too strong?

My guess would be either it's still acclimating to your tank or its not happy with flow placement. Not an expert by any means though

How long have you had the coral. Have you checked your magnesium level. Any recent changes in salt water mix. What color temp are your halides?

I've had the coral for about 1 month. Its getting bigger but its losing color. My mag =1360, alK=11.8. I did change my salt mix ( was told that it wouldn't hurt). How do you find out the color temp on the halides (never heard of it)??

10k 14k 20k bulbs are the color temp

Where can I look to find out?? On the bulbs or ballast??

[johnnymisty]

It should be on the bulb

Other than not know what color temp your lights are. Your coral is aclimating to the new tank and new salt mix. Give it some time. Lighting makes a big differnce. If you are 10k then you are going to see great growth but not much color. 14k is kind of the in the middle. Great color pop normally comes form 20k. You could always supplement with actinic pc, t5 or vho if you want both color pop and growth. I am currently running 14 k 250mh with 180 watt pc actinic on my 54 corner tank. I like the 420 nm actinics best. the 460 actinics are more blue, the 420 is more violet.

I just checked my bulbs and I have 10k. Going to the LFS to see if they have any 14k bulbs.

check your PO4 first lighting may not be the problem
