Yellow acro turned green. Lighting?

[powder_blue]

I bought a nice acropora aspera a couple of months ago and after about 2 weeks it went from yellow as a banana to green. Plenty of pe and growing like a weed but I bought it bc it was yellow and not green. I've heard thar lighting can do that. I am running and 6x54w sunpower on my 90. Bulbs are 4-blue plus, 1- coral plus and 1- purple plus. My params have been solid and i keep my alk around 9. Thoughts?

Do you dose iodine?, i so, stop, how is your PO4? If its high try to lower it, my yellow corals get green when i dose or should i say overdose on iodine or my PO4 is present, good luck

I remember reading somewhere that with lower light the will be more green and with higher light they will be more yellow.

No iodine dosing and I have it at the top of my tank so it's getting plenty of light. I use kalk in my ato along with randys 2 part.

I have a Shawn Bennet yellow tort that is as green as green can be. The funny thing is that when I frag it the new frag grows in yellow. All under the same lighting so go figure.

Mine is so florescent green that you almost need sunglasses.

I'll have to frag it and see if it works for me.

Probably lighting.

IF it was a wild or maricultured sps them I would expect it to have a color change going into a captive system with artificial lighting. I got a few true yellow sps over the years and all either changed color on me to a more greenish or they died. All where maricultured . It is hard to keep the yellow in sps corals it can be done but you need good lighting, flow and low nutes.

Stag lower left when i bought it 5 weeks ago - straight off the reef and in a filthy new tank - yellow.

Today its green in a much cleaner tank, i think lighting plays a large role but who really knows for certain.

looks healthy now, I'd say it's supposed to be green. I have 1 yellow acro that has yet to turn green, every other one has turned neon green.

Agree mate, it's polyps are fluoro green and it's growing well now that it's settled in. Very pale blue, almost white wild colonies are often dying purple colonies well on the way to bleaching and RTN. I have a frag of it as close to the halide as possible getting baked and it is only slightly less green but the whole thing is much more fluorescent and it is encrusting the plug very fast.

Looks healthier now. +2 on green being the original color.

I have had many yellow Sps over the years and when nutrients get higher they alway turn green. It's never anything else assuming lighting is the same.

I too have had a few yellow colonies over the years and i would tend to agree with you if lighting variances are removed. I have also found that the finer delicate branching acros hold yellow more often than the thicker stag like sp. - just in my experience.
Most 'yellow' SPS i see in pics are more fluoro green than yellow but we as reefers tend to fudge on the color call due to wishful thinking.

It is def a maricultured coral and the store I bought it from had 12k halides. My ATI is more of 16-18k. Growth has been outstanding so it's definitely healthy. My nitrates have always been .5 and doesn't seem to move. Phosphates are always 0 but I don't have the $200 phosphate meter. Glad to gear what others have experienced. Thanks!

This is completely normal for corals to change colors in different tanks. Lighting, flow, and nutrients will all play a major factor in this. I have a milli in my tank that i fragged and glued down only 12" away from the colony and a little higher and its a totally different color than the colony. I have several corals that are one color in my tank and another in other peoples. Maricultures are infamous for this and one of the reasons they are my favorite to buy. Its always exciting to see what they are going to look like when they color up in your tank. Since your not dosing iodine and your coral is healthy i would say this is the color its supposed to be in your tank.

Unless you're running lower kelvin lights, many times yellows turn to greens unless you basically have no excess nutients in your tank.

This is one of the best yellow to green topics threads I've come across, would like to see it continue. I have a yellow scroll coral turbinaria and it's the only yellow coral I've had luck with. Also got a strawberry acro, and the base has a nice yellow color. Both these corals didn't change with either lighting config of pheonix 14k's or ushio 20k MH - led supplements of natural white, and royal blues. Few months ago I bought some pink lemonade and it's green for me. Pink jade, and it's green too. Yellow and true red are hard to come by IMO.

Ya most yellow acros are going to turn green if moved under a higher kelvin bulb. I had a banana yellow millepora turn green by doing the same thing.
