What the...........................

[schigara]

I guess things can only go well for so long.

Stability is great and all but still crap happens.

I have a SPS coral that just RTN'd and is totally gone in a 36hr period and another has started RTN'ing.

DKh- 9.6 all day and night, month after month
Ca- 440-460
MG- 1350
PH 7.99-8.29
Temp- 78.1-.78.9
Nitrate-0/undetectable
PO4 undetectable
Ammonia & nitrite- 0
Flow-40x and unchanged in months

Pictures are pre-RTN

Dying

RIP

That really stinks I know you have really put a lot of work into your setup.

It stinks to lose anything you work with and care for like this stuff. Hopefully you can find out what it is and put a quick stop to it.

I wish you good luck!!

What changed in the tank?
Addition of Probidio?
Temperature change?
Different light bulbs?
Anything at all?

 

[schigara]

Light change was June 7th and I raised them about from 10" to 18" off surface and slowly, over a 2 week period, lowered them back to 10" off surface.

Probidio started 5 weeks ago and dosing is per instructions.

No changes in temp and fluctuations throughout the day are less than 1 degree.

Do these things just happen sometimes for no good reason?

RTN comes and goes from my experience. Its usually something as inperceptable as a slight fluctuation somewhere to a small coral war that began and ended overnight. When it comes to RTN you will want to IMMEDIATELY frag the specimen. Take a frag that is as far from the RTN as possible. Remember you want to save the SPECIES, not the SPECIMEN. Meaning. don't try and get a huge frag, just something workable. And take as many as you think you can without doing more damage than the RTN is already doing. I took two small fingers of an acro I had once (they were probably 1/4" on a hand size colony) just in case I lost the whole thing. Long story short, my colony died but the frags lived.
As far as treating RTN goes I'll let someone with more exp answer that. I had no luck treating it. I just held my breath and prayed it made it. I have had one other RTN and recover on its own. But with a 50/50 track record I'm just not exp'd enough on treatment.

AEFW?

 

[schigara]

I don't think AEFW. I have looked as closely as I can and didn't see any. They are mostly clear-light tan brown in color?

 

[just dave]

It could be a combination of things. Higher intensity lights, less nutrients, use of carbon or ozone,...etc. It might not be just one thing. That doesn't look like AEFW from what I can see as I don't see the mottled bite mark appearance generally associated with their presence.

RTN?

rapid tissue necrosis

 

[DrPeaches]

My tank has been operating and stable for about a year, and my growth as been incredible. I started Probidio in March to help me cure a water-quality problem (of my own making), and it cured the issue. In May or June I added a few Acropora frags, which all grew nicely for about six weeks until one just up and died. The rest continue to do fine.

I think the moral of the story, as you declared in your first post, is "stability is great and all but still crap happens."

 

[spshead01]

Are they Aquacultured or maricultured frags because I have had the best luck with mariculture corals?

 

[schigara]

I think the bigger one was straight up pulled from the ocean and the other was aquacultured.
