My Acros all turn Green

I agree with the transition color. I have saved many brown outs and there is always a green phaze for a few months. Are all your acros green or just most?

Ill back this statment up, it is happening in my tank right now. I bought a browned out millie frag that was originally blue. I slowly acclimated it to my lights and now it is about 6" under 250 14k. At first the edges started turning green and now the middle and tips have start getting a nice blue and purple which is starting to take over. I have even already noticed growth after about 3 weeks (im pretty proud), the only thing that i dont like is its brownish polyps which completly cover it. Will polyps color up also? JME, maybe some of your corals are still going through this process..?..

I never have this problem unless the corals go into my not so low nutrient prop tank .

Coral in my display either stay the their og color or color up from brown . Never go from colored to brown and back without some sort of nutrient problem .

I can get a dirrect import and have it hold its color no problems.

Ok, that makes sense. I just moved on July 1, and I lost a couple of fish, as well as having a couple of heat spikes. My tank certainly wasnt what it should have been. Had a whole lot of browning, so green is probably a good sign at this point.

Although the purple tipped acro that is now neon green (and I mean like old school Ecto-Cooler type green) with red highlights is WAY nicer than its ever looked....

As to the tank, I think its at 440 ca, 9 alk, 1350 mag (was when I checked a couple days ago..kalk seems to keep things pretty steady). I've got plenty of flow (58g, 2xMaximods, 2xSeio820, Tunze6060, and 200gph return), I've got a hugely overkill skimmer, and I run 2x250w MHs, one running an AB 10K, and one running a Geismann Megachrome, so

Almost all wild acros do this - brown, to green, then surprize color maybe 6 months later (reefermadness frags). The tank raised aquacultured hold color better - an ORA Blue Tort almost always stays blue.

6" under 250 14k? It seems to me that it is so close. How high is your MH above the top of water?

I have a pink and a blue mille about 3 inches frmo the surface and my MH is about 6 inches from the water. The thing grows like a weed. IMO Mille's need alot of light and they color up nicely due to it.

I think you should check the iron content of your tank, do you dose iron currently?.

Green corals are usually an indicator of high phosphate. Don't know your parameters but you might want to double check your PO4.

Im thinking its the spikes in the color spectrums of the halides your using along with a few other things. If you read some of Dana's Writing you will learn that coloration is generally just a defense against the UV that we expose the corals to in our Tanks. Honestly to keep them there true colors you might wanna try setting up a small prop tank with a 6500K Iwasaki and leave them 3 months.. One of the best looking tanks I ever saw was with 250 watt iwasakis with 250 watt 20k bulbs to fill in the yellowing . 10 K bulbs tend to spike very high in the lower end of the 420nm range which could indicate the reasoning for the Green'ing . Over feeding could be another factor to.

DO you skim your tank Dry or Wet? Ever Use Carbon to polish your water?
NEVER Put carbon in your system at night before ending of a Photoperiod as well. It will drastically change your PAR rating in your tank the next day.. Always put carbon in right before your lights come up ,, so it gradually pulls out DOC's .. I dont think Iron would be it either.....

Lighting and Nutrients..... Alk Spikes..

Nuclear Reefs asked me to chime in on this thread, because I'm famous, no... legendary at turning all SPS green in my tank.

There is a good chance your water quality isn't as good as you think it is. Typically, brown SPS mean too many nutrients. Green SPS could be due to excess pollutants as well. My reef has a lot of green in it, but some are corals that are actually green. I have others that have pink, blue, teal, orange, red....

I make it a point to siphon out detritus every three weeks from my sump. I clean my skimmer's collection cup and riser tube at least every 48 hours, if not daily. I do run carbon, and I'm dosing Salifert Amino Acids every 14 days. I have tons of flow (as much as 12,000gph) in my 280g reef. The refugium grows and removes nutrients. I do a water change at least monthly of 55g. I do run ROWAphos-type media, and my water parameters are exactly where they need to be based on my last test.

Matter of fact, have you tested Magnesium yet? Is it 3x the level of calcium? Can you post all the water parameters please, and what you are using to measure them?
