Help with tissue necrosis.

[TonyB]

I suppose this is what is more commonly known as Slow Tissue Necrosis. I've got a couple colonies that are slowly dieing from the base up. It seems that a little less than 1/8" recedes each day or so. It's affecting a good number of my corals so it's not picky, lol, which makes me think it's symptomatic. It's affecting my A.plana, A.verwerii, A.yongeii, A.efflorescens, A.austera.

Have any of you come across anything that can help with this situation?

Tank:
120g
2x250w reeflux 12k's
2x vortechs
Octopus Xtreme 200 skimmer
Red Sea ozonizer
GEO-624 reactor

Parameters;
pH 8.0
Temp 79
SG 1.024
ORP 390
Ca 390
Alk 9 dKH
Mg 1290

All of my testing procedures were verified a couple weeks ago when I sent a sample into aquariumwatertesting.com

=Have you checked for aefws?

Is your alk stable or does it swing at all?

Forgot to mention that it's also affecting my Miyagi tort and blue tort. The Miyagi is taking the biggest hit.

I have checked for AEFW's, I had them a while ago and tore apart the tank to get rid of them. I haven't been able to find one or any eggs since. This tissue loss looks completely different than the damage sustained from the AEFW's.

Alk is stable. I've been checking it multiple times each day to be on the safe side.

Thanks for the replies!

I seem to notice it if my Alkalinity shifts, and my millepora's always seem to show signs first. If it gets bad, or continues to progress I try and cut away the dead portions and remount the healthy pieces.

I wish I could tell you that was a for sure fix to stop the spread, but I've only had about 50/50 luck with that method.

L OOK AT NIGHT WITH A FLASHLIGHT you may have seaspyders.....I FOUND THEM eating my sps from the base up....3x interceptor took care of them.... they look like daddylong legs....

Y OU MIGHT TRY A 30 MIN DIP IN REVIVE..... It has never hurt a coral of mine and has stop some corals from dying on me....IF it is a pest this should take care of it.....check out jan/03 back issue of reefkeeping about spiders and pests buy ron shimek......revive can remove some bacterial films also.

Just out of curiousity, do corals react negatively like this to high phosphates?

 

[TonyB]

PO4 is .04 according to my Hannah and .03 according to awt.com

Last year the levels were as high as .76 and the only symptom was slow growth, no loss of tissue.

Are these one of the symptoms of high phosphates? Just curious

Yes, it can be.

I just got though... I hope, a bad case TN myself. I never did find what caused it. My parameters were all in check also. What I had seem to speard slowly. I lost a few and others I lost most of the coral. Only acro were effected for me, but not all of them.

Since I couldn't figure out what was the cause, I decided to just see if I could stop it. Remind you tis occured for a few months. What I did was cut all of the effected area 1" into go tissue. Then seal the newly cut area with super glue. This worked for many of them, but not all. I also did two 20% water changes per week, with a two salt mix, 1/2 of seachem (normal salt used) and 1/2 IO.

What helped the most and I say this because no other corals have seem to be effect since I applied this was to move all effected corals into a "QT" setup. I held them in there for a week and if all TN stoped, I added then back to the display.

ON a side note I also ran 12k reeflux or did. How old are your bulbs? IME they tend to drop in preformance after 8 months.
