poss. rtn on sps please help need advice

[irocz2280]

Ok so i am having an issue with some of my new frags and now my larger colonies of various species: Green slimer , poccilipora , a few different acros, and pink BN , i think it may be RTN but unsure it started a couple of weeks ago after adding a few new frags to my tank they were recently fragged and because of great price i had to jump on them. learning my lesson the hard way on that one. my levels in the tank are in good shape tested all these with hanna meters, phos. 0, calc. 444, alk. 10.024, then nitrate <10 I did not test magnesium because my last test kit is depleted but will be testing very soon. I also dont dose anything and have a calc reactor running on when lights are on. here are a couple pf pics of what is happening. In first pic the two corals touched so i think its some kind of attack on each other but its happening to multiple others that are not touching.

how are you keeping up with their ca/alk intake and how long have you had the colonies

 

[Mattl22]

I would definitely clip away the rtn parts!

 

[irocz2280]

As i stated i am running a calcium reactor and have very stable calc and alk so this is why im a little stumped. and i tried clipping the frags and it just comes back on the freshly clipped end so idk.

I have the same thing happening in my tank, i'm not an expert on sps, but i think that is growth, i leave mine alone, unless it starts to turn brown

could be many things.bacterial,water quality,bugs maybe some warfare.is it happening very quick or slow.also had a couple frags do this in the past 3 weeks.2 to be exact and i ended up clipping them and dipping them in RX so far they are doing alright

 

[irocz2280]

I need to dip I think

hey, silly question but have you been sick latly? ive read that if you have a bacterial infection(flu) and you are messing with the corals that you can pass along some sort of bacteria that will kill off the flesh of the coral.. also if they have a bacterial growth on them that they will die even if you clip them back, best thing soetimes is to clip them well into the healthy flesh and let them be. a dip may help as well

incase someone thinks im making it up,
there was an article called "pathogen shown to cause disease in elkhorn and acro palmata" nov/dec 2011 coral

Actually my girlfriend and I recently were sick funny u say that

i dont know how true or proven it is, but i read it and it seems to be an issue with some forms of sps, hoped it helped..

 

[duke62]

HUH i had a sinus infection when mine were stning.would be great if there was confirmation on this.i need to look up that article

 

[motortrendz]

is mostly abt elkhorn and another sps.. but if one is suseptable y wouldnt others???

 

[homegrowncichlid]

when I get random die off like that, it's because something (like a hairy mushroom) got shreaded when I scrapped it off a rock or I fragged something, and the stinging cells were released into the water, hitting other corals.

Sps need some phos. Zero phos starts rtn for me. I like to keep my phos around .02 to .04. Also if the frags came from a higher phos enviroment into a zero phos enviroment this may cause the rtn.

That was a specific viral infection from human waste causing die offs in caribbean corals, mostly a. cervicornis and palmata. I have yet to see any document that implies a connection between a tank owner and their own tank, but it is not beyond the realm of possibility.

Typically when we talk about RTN we are referring to an SPS coral dieing completely in hours. Various small areas of die off would be considered something else.

+1 The "R" stands for rapid. That is not the case here. As stated above it could be any number of things and it happens from time to time to all of us. The 1st thing I always check is the salinity. When was the last time you calibrated your refractometer? Unless things start deteriorating much more quickly, I'd take small steps like pruning out the dying areas ( well into healthy tissue as suggested) and increasing/ changing up flow to the colonies. Don't make too many changes at once since you'll never be able to figure out what is helping or hurting. If things continue to spread and worsen, then you can explore more extreme measures like dips and UV etc.

Well I snipped what I could and crossing fingers
