STNin on same stag

[duke62]

i have tis beautiful baby blue stag that i desperatly tryin not to lose.when i first got it it did well for 3 weeks then i noticed some STNin at the base of the coral.i cut the base and dipped it in coral RX and it did great for 2 months and as soon as it started getting a good encrusting base it started STNING again.i did the same routine and it started growing and branching and again a nice enrusting base and again 2 months later STNing.so yet again i did the same thing..what can be goin on.there are no bugs in my tank and i move the coral aroud to see if it will be happier in another spot.i really dont want to lose this peice.i have never seen a stag like this one.my alk is 9.3 and im trying to lower it slowly to around 8.5.been adjusting the calcium reactor every 2 to 3 weeks to acheive that alk.but its just weird to me that its the same coral over and over again

Duke is your alk swing?

Ime stags are very sensitive to alk swings

 

[duke62]

i have 4 different stags in my tak and they are doing fine.unless my calcium reactor is messing up i cant see how it could be swinging.

Ok just an idea

Clearly it is weakened and susceptible to subtle changes and/or pathogens. The truth is unless there is a system wide issue, you will never really know what the problem is. There really isn't anything to do except what you are already doing.

thats what i was thinkin pratt.its just so irratating that it grows so nice and i have to chop it every 2 months and lose its growth.but what i am wondering is why it starts to STN when it encrusts to a certain point.

 

[prattreef]

That is a good question. Sorry I don't have clear answers for you. My speculation is that once it reaches a certain size it cannot, for some reason, fully support its metabolic needs.

 

[duke62]

that sounds like a reasonable explanation.oh well as long as i can keep it alive through the process i am doing now i ant complain.it is a beautiful piece.

Is it mounted to a rock or on an plug. If a plug could that something in the material the plug is made from is irritating the coral. May not happen right away because the glue acts as a barrier but when it starts to encrust, its direct contact with the plug starts the STN. Just a thought ...

Duke I was having same exact issue with a few my sps ! Was going crazy looking for aefw! Thank god didn't have them my alk was 9/10 and I vinegar dose bad combo!

I say let's experiment chop a peice off and well throw it in my tank duke let's see what happens plus if it dies of in either tank at least u will still have a frag of it
