Acro Bleaching

[ezcompany]

So i have recently removed the teddy bear gorilla crab.
And now my acro seems to be bleaching from the right side. Is there anything I should do? I recently moved him up to higher lighting and more turbulent flow.

Tank specs:
24 gallon aquapod, ammonia trite 0, trate <5, CA 400, SG 1.024-1.025, Temp 80F flat, lighting 150 14k Sunpod, less than 9 inches from the light. not 100% directly under the bulb, a little to the side.

Here is a pic

bleaching side

any help would be very much appreciated. thank you SPS masters!

here's more information.
the acropora was already bleached in the base, but i thought this was from the gorilla teddy bear.
the acro was under a surge system from the lfs.
the acro gets moderate indirect flow in my tank, no powerheads pointed directly at it.
it was light acclimated (placed in mid level) for 1 week, then moved up to the top.

Is there tissue on the parts that look white? Looks like history to me.

frag it quick!

 

[ezcompany]

there are no tissues in the white areas, yes its history.

how should i frag it?
the bottom of all the stems are already white should i frag every stem??

 

[Frankysreef]

frag it a 1/4 inch above the white and replant.

 

[ezcompany]

so i'm gonna be fragging every stem, and into the color?

 

[Jeffie]

Yes, if you want to save any of it... Frag as many possible healthy branches as you can. Frag it as frankysreef said..

 

[PL-Reef]

thats sucks dude. i have a wild colony do the same thing...RTN

 

[ezcompany]

ok i fragged it. (cut myself while at it, i forgot how sharp stony skeletons are)
i have fragged some with the bleached part, and some with only healthy parts. some are placed under direct light, some are placed in the bottom of the tank. hopefully i'll get to the bottom of this.
the LFS was kind enough to offer me a replacement acro

Now thats a cool LFS ......

 

[ezcompany]

can the RTN spread to other sps in the tank?

 

[clkwrk]

YES

 

[rockindacheeks]

noob question... what exactly is RTN?

 

[clkwrk]

RTN= Rapid Tissue Necrosis

 

[rockindacheeks]

thats what i thought. how would that spread to other corals? ok this is the last one... sorry for the hijack

 

[clkwrk]

Tissue sloughs off with its bacteria flies around the tank lands on another acro....If the acro isn't 100% it has a chance to get the infection.

 

[reefman77]

does anyone else think it might have been caused by those zoanthids? I recently lost an acro colony that fell and landed on my zoas. they seem pretty close

 

[clkwrk]

I personally have never lost an acro to zoanthids. I have had an acro kills palythoas and I have had zoas growing right next to the bases with no problems .

I have even had monti grow over the top of some zoas
