Sick Blue Acro

[richfavinger]

I've had this frag for about 3 months, when I got it, it was beautiful blue and now has since gone green on me with white spots I though was new growth, but no? Now forgive me guys but my vision is very bad, thus the provided Macro photography shots.

I'm holding it upside-down from it's plug for a closer shot...
Note I see some polyps and the white marks. All other corals, clam, shrimp, fish seem fine.
:sad2:

sorry to tell you but the acro is dead. The white pollyps are barnicles if iam not mistaken. What looks like to me is you have alot of p04 in your tank. When an acro skeleton looks like that is becuase of high po4 or a bad algae growing inside is and thats why it died. Sorry for you loss.

one other thing I noticed is that when acros are left on the plugs they seem to do this much faster since the plugs are made of concret thats why I always remove mine from them.

I agree with Mchava, and the fact that the skeleton is green is probably due to high phosphates. I'm not sure if leaving it on the plug matters, however.

Did it changes suddenly to that from it's blue? or Slowly over weeks?

 

[richfavinger]

It was over weeks, but then kind of brown to this in about a week.
My NO3 is less then 5.0ppm, my PO4 is under 0.25...
Guess I'll add some PhosBan...

.25 po4 is high IMO. I don't let mine get above .03

Enlarged about 50%..
I assume they are polyps, and he's OK. Sorry to act so dumb, but there not like an LPS like I can SEE there OPEN... LOL sigh... Threw the camera every thing is dandy, in real life I am as blind as a bat.

If you use phosban or rowaphos, be sure to go "slow" with it (eg. don't use the full recommended dose), as it can cause major bleaching. Do a search to see what I'm talking about.

Green means some kind of algae not skin of sps.
First two pics shows alive one but othr pcis show that all dead one.

The other coral looks healthy but how green was it when you got it. Has it changed?

 

[richfavinger]

The green (tan?) color acro has not changed since I got it. I had pulled 3 little crabs off it. Other then that, unchanged. Both corals where to be Aquacultured.

Thanks for your help guys, I cleaned the filters, and added some PhosBan (was using PhosGard) and I'll do a water change in a day or so. As mentioned all other corals, polyps, mushrooms, clam, fish and a carpet anemone are doing fine.

My CPR AquaFuge 24 is filled to the brim with Macro'...and 4" of MM. But as I though from the start, it may just be too small to keep levels zero, although it has helped with NO3.

Well the phosban should help, just start slow. I didnt think the phosguard did much myself. I have a phosban reactor. It works wonders. GOod luck.
