Does RTN always kill?

[dots]

Obviously, if one doesn't correct the situation it will, but I had caused some high alk and some nitrates. In turn, this caused some recession on some encrustation om some new conlonies.......


I don't want to loose months of growth to one little mishapt.....can I recover from a little tissue loss...or will it spread.....

some is from the top-down, others from bottom-up....

Problems are corrected......

Question is, once started is RTN/SRTN reversible once some is visible?

Never for me man. Monti's or acro's. Frag off and lessoned learned.

I have had colonies recover after 90% tissue loss due to shipping stress. This was before I found out that fragging-off was the best course of action. Some recolonization took place but eventually I pruned-off dead skeleton because It was very difficult to keep algae from growing on it.

I have also lost a couple because I hesitated; the necrosis became contageous and next mornin I had a nude coral.

Frag-it!

Same here.

In the past, would panic and frag what tips where left, but that too was hit and miss. So now, I just let nature take its course after I correct the problem. Most of the time the problem is alk related.

Agree that STN is usually alk related. IME STN is usually reversable and RTN(a true shut down reaction)is allmost never reversable. If the corals are stressed for an extended period of time STN will likely lead to RTN.

How high is too high for alk? I bought a bunch of frags a few days ago and a couple are receding. My alk is ~10 dkh.

10dkh is good. The problem with STN and alk is usually from Alk going up or down too quickly...as in not stable.

i def.. agree with that... my alk before i new what i was doing with the chemistry part of this hobby was about 4dkh.. which is really low... and it would def. take big swings.. my pink birdsnest started to rtn on the bottom it was completely bald (naked) maybe like a cm or 2 up... i read and corrected the alk problem and now its fully recovered and growing big and strong...

so yea alk would have something to do with i say either stn or rtn....

Ohhh I just pulled a newbie and got lazy dosing the b ionic a couple of days......it was so depressed it wasn't helping much, so I decided to put in some powdered buffer to get it where I needed......

I use the proper ph 8.2 and have had great results from it, but add just a little too much and shot the alk to about 12 or 13......

did some water changes but you know once this all starts its hard to recover.....a cascade of trouble has started since then.....

Some localized STN mostly on some really encrusted pieces, and since I have 150 DE MH's, that kind of growth is hard and slow to come by.

Its a slippery slope you see, your invertebrates try to die on you which could cause a spike, my anenome got caught in the powerhead last night, (it had detached because of the alk after a year in the same spot), luckly it wasn't the foot or mouth that got caught so it looks like it will make a recovery. However, my spinecheek clown wouldn't leave it alone so I caught it, durring which the spines got caught and nearly pulled them off.........

Lesson: Be vigilant and always do your husbandry on time!!

Back to the SPS, I noticed a little more recession today, I agree that it is probably STN and think I will ride it out, unless I have to cut and run, but am not looking forward to it.

I bought a piece a week before this happened, and of course it showing the worst of it being already stressed, but this morning noticed a green tinge to the whitened areas, and do not think this is algae. Do you think it is a possible regrowth telltale sign?


I believe my problems are definatly because of too high alk and two large swings back and forth. I am usually very up on it and keep it around 10dkh.......great results until now. I agree, as long as it is in the range, stablility is the key, however thats somewhat of an illussion to me right now!!!
I may post pics tonight/later

Thanks, Doug

Get it stable and watch closely.....if reccesion is still occuring then maybe frag...but try to wait it out if you can. If its not too bad they will most likely make a come back.
