Frag issues

Scubasteve23 · #1 12-29-2010, 07:06 PM

Has anyone who went to the Lethbridge Frag swap in Nov experienced any STN? 80 % of what i purchased at the swap has developed some STN of some kind. IT all seams to be slow moving but is there none the less. My brother inlaw also had this problem with some frags he purchased. Just wondering if this is something that more than just the two of us are dealing with or if anyone else has had these issues???

On a side note, anyone have any suggestions as to what i can do to save some of my corals? I was told to frag what i can while i can before they die??? but do i then remove the rest of the coral??

Also want to add that this is just a question and in no way to be interpreted as an attack towards anyone from the swap as i believe we got amazing corals and great deals. I would go again in a heart beat.

Thanks
Steve

Frag what you can and soak the rest in Coral Revive? May help, can't hurt.
Sorry to hear that.

I was there and got a couple of pieces...so far they are doing ok. Sorry to hear about your problems.

I've had no problems with stuff bought or frags of mine either??
Any chance of a pest in your system? aefw?

All of our frags from the swap are doing really well, with the exeption of one small frag that didn't make it. Did all of your pieces go downhill at once or over time? Do you use tap water or R/O?

if its happening over time then its stn, not rtn

what are your parameters????.....

Sorry STN...I will post parameters tomorrow for those who are interested. I also found what appears to be a reddish copepod or amphipod today. I have never seen one of these so i have no idea what it could be..maybe it is the source of some of my issues.

Don't concern yourself with the RTN/STN terminology, the term doesn't even exist outside the hobby and there is no exact time to distinguish between the two (they're both relative terms). Tissue necrosis is more of a dis-ease than a disease, caused by an upset in the tissue function due to changes in any of the external factors that corals depend on to survive. RTN is not caused by any specific bacteria or parasite, although an attack by such an organism could certainly trigger tissue deterioration, either fast or slow depending on the sensitivity of the coral. RTN is most apparent in Acro and Pocci corals because of this. You need to consider that you picked these frags up in Lethbridge, drove 2 hours to get home (did the temp change significantly in this time?), you acclimated the frags (how exactly did you acclimate?). If your water parameters were drastically different than the frag tank (especially Nitrate levels) it could very well shock a sensitive coral. Did you place the frags in too much flow or not enough flow? Did you place them too close to the light? Something as simple a soap residue from washing your hands and touching a coral is enough to kill it. Why don't you post your parameters AND a list of the frags you bought. You said 80% were affected, were they mostly SPS? You had mentioned a Devil's Hand deteriorating, soft coral are pretty resilient, if you have a dieing leather coral I would really take a look at tank conditions and parameters. My point is there are a lot of factors to consider, you probably should retrace your steps and you may think of something you might have done to trigger this.
