Adivce needed:

Tank is established. Water parameters are consistant and correct. Dosing alk/calc/mag. Low nutrient, large skimmer rated three times system, 8 bulb ati t5 w/ reefbright led.

Have acros including three oregon torts that have grown to close to 8" ca torts, several yellow acros and all shift to green. The yellow turns to a light green and the torts to green with blue tips......Garf's etc all color but don't hold correct colors yet growth on all is good.

Any ideas ..... I have a stuffed and somewhat overgrown tank full of green acros...even tho the only green piece I bought was an ora frog skin....which did hold color!

Thanks
 
What else are you dosing / Check your Iron / careful with Aminos / series of 20% water changes until you have changed 100+%
 
Light.

I've had a 4" colony of lords slowly shift from dark crimson to dull orange / green over a period of 4 months. Very healthy and growing, but the color change p!ssed me off obviously. Rather bright lighting in my tank, but they are tucked to the side. Nitrate levels are steady at 5. Color stays the same if I feed them or starve them.
 
What kind of lighting? Ive found this is what happens with leds... lots of my acros shifted color when they went from being under T5s/LEDS, and now under just LEDs.

I made the switch to LEDs and now multichip LEDs some time ago. The multichip has blue, royal blue, neutral white, cool white, and two violets channels at 2 different nm.

I'm gonna be going back to T5/LEDS as soon as I get time to mod another TECH fixture.

BTW, nothing else in my system changed except for lighting when this happened.

Op listed ATI T5s with Reefbright LEDs.

It takes time for corals to adapt. Just because they are growing doesn't mean they are fully adapted.

I had a yellow lokani that was bright yellow when I got it. Was grown under Radions. Turned green in my tank under Kessil AP700s. But have now returned to yellow. Took over 5 months.

Exactly this -- Typically when I get new corals, especially if they traveled to get here they show up browned, then they shift to green, then they color up.

Fresh WYSIWYG frags show up colorful, shift green, then color up to normal.

It seems that when corals produce Zooxanthellae (which is a form of protection for them) they will fluoresce in Green hue's, probably due to said Zooxanthellae.

So when a coral is placed in a new system, it will have to adapt, and may still encrust and grow while adapting.
 
The fact that the op used the words overgrown and grown to 8" makes me think the acros have had time to grow and color appropriately. Which is why I would like to see a picture.

I agree here, when under new high lighting and water conditions I believe the coral produces more fluorescence and possible higher photosynthesis levels giving the coral skin a green color. I have seen this is some corals and it goes away after the coral have settled in. You may also need to move the coral where it isn't getting so much light. I find that if everything remains stable the color will return.

Additional is minimal -1 ml each, flatworm stop (as supplement) - acro power- potassium. I give precisely 2 drops lugols per week and about monthly 1 ml iron.

Water is IO.

Thanks for input

Exactly- had two separate oregon torts .75-1". Blue as blue gets, no underlying shades of green like a cali. They grew and branched. One died and had a chip laying on its side about 1/4". It didn't die and now has grown arms outta side. The survivor is 2 branches one 5" plus the other over 6" from their common base. The all have green cores with blue tips. The two frags started from different sources.

As for the lights the t5 ramps two bulbs first hour then the 6 for 6 hours with reef brute joining the last two with them stepping down wt just ne'er 8 htrs total on. Have yellows. Aussies, pikachu tank raised all also shifted green.....will postomorrow....tho they will be cell pics....

Thanks

Either of those could be it right there.

When I was dosing Lugols I had everything slowly turn green. I have not dosed iron, but iron directly affects green coloration as well.

Probably give those two a rest, and do a series of large 30% water changes, until you change out 120% of your water (over like a week or week and a half). After WC, lay off the Lugol's and Iron and watch what happens.

What would the water changes be for? Iron and iodine both are not elements that stay in the water long at all from what I understand. Either getting used by corals or depleted by other means quickly. But stopping dosing surely won't hurt anything. I never dose iron since ime it doesn't do anything. Some people use it for green colors according to that one "color to element" list online but I don't believe much of that list is really accurate or useful.

Get some pics for us op.
