Rapid Tissue Necrosis

[EdandSandy]

I had a major nitrate problem in my tank, we did 2 80% water change outs, trying to keep the water parameters as close as possible. We lost our huge plate coral, not sure if it was from the stress of the nitrates or the water changes, now I seem to be battling RTN., it was on my acros's did a lugols dip a couple of times, that really helped, now my red blasto., is showing signs of RTN. My question is:
Is this like a cold in the tank, is it setting off a change reaction?

When doing large water changes, salinity and temperature of the new water must be very close.

Nitrates generally won't hurt corals.

Give your blasto time, they can recover from almost total tissue loss.

Thanks Rob,
I have posted this question on several sites, you have been the first to answer. Is the RTN, like a cold? it seems to be spreading around the tank.


The corals I got from your shop- are still doing fine.

I have had corals RTN w/out affecting any other corals. So I would not think it is like a cold, but I could be wrong

[Robwsup]

No, RTN generally affects one coral at a time. It's not communicable.

Bleh. One of our Blasto frags has pretty much lost all its tissue... you said it's possible it could completely recover, Rob? Anything we can do to help it recover? Any idea on why it's lost its tissue?

Whats near it? Are these blasotmussa merlittis or Blastomussa welsys? FYI., I have seen welsys come back from slight RTN or other chemical fighs with other corals. I have seen entire colonies of merlittis wiped out in quick order. What caused your nitrate spike?

[EdandSandy]

They are Blastomussa welsys, I dipped them in the lugols 1 time, and they seem to be doing better now. I have been watching them closely, with a maganfiying glass to be exact.
they are near some acros.
I think my nitrate spike was caused by me being a newbie, over feeding, not changing the socks & filter media enough. This has been a very expensive lesson.

seems like the water changes may have shocked the coral...nitrates won't usually cause rtn
