coral stn

One of my goniopora has been having polyp bailout from what i think is a bacterial infection. should i dip the others as a precaution? are there other options for treatment? i have lugols solution on hand

I dont know if this has happened to anyone else. But let me start the story I started dosing my tank with AB+ yesterday, After watching several videos showing how, and talking to several people who have used it, I went out bought some AB+. followed the dosing amount and how to dose to a T and...

Unfortunately my tank is suffering from a STN event to a red montipora cap that is slowing spreading to the Digitata that it touches. It potentially started as brown jelly to one of my gold hammers but can't be sure. I was hoping this would be limited to only the cap and took measures yesterday...

I put several new corals in my 9 month old 65 Gallon tank 2 weeks ago. The softies, LPS, and one SPS (montipora) are doing well, but one acro is losing color and the other acro which arrived brown looks like it is bleaching at the base. Should I apply super glue? I'm worried it's too small to...

Recently I've had some tissue necrosis on a couple of of my acroporas. One tenuis rainbow and one frogskin. I'm baffled on why this happens. The frogskin seems to be stn and the tenuis seems to be something else, bacterial attack? A few months ago I could see a couple of dead spots on the...

Is this stn or tissue die off due to shading? It seems to be bleaching very slowely. Over the last few months. Could it be due to how those spots are now shaded due to placement? Thanks all,

Dear All Got this Neon Green Bird nest last evening. Dipped in Coral Rx before placing in my tank. There is a white lesion at the base of the stem. I believe it was there when I got it from LFS, I have failed to spot it. Is this Tissue Necrosis? I have never fragged corals before. Please...

For the past 2 months, I have been dealing with slow tissue necrosis (STN) on many of the SPS in my tank. Multiple mini acro colonies (~4 in) have bitten the dust and I cannot figure out what is causing it to happen. Also, some SPS frags were also affected by STN while just one of them succumbed...

I'm losing some monti I've had since I started my system. I'm thinking it could be too much lighting, my alkalinity was sky high a few weeks back but these montis have been STN since about Christmas time. I have a full sized one that is completely healthy and it seems only these two are doing...

So I decided to remove my PC rainbow to dip it because for some reason it was STNing and found this.
