LOL!! So true!
In our hobby, there are some usual suspects. Aged lights, bad parameters, chemical warfare in a mixed reef........to name a few. I had an episode where the coral growth just took off and caught my dosing flatfooted. Alk went down to the low 6's before I caught it. Some coral started to show STN, but most significant change was the coralline: they all turned white.

Im going threw it right now. Its onky happening to coral I have fraged in the past 2 weeks and one hardy coral...
My alk cal and mag are all stable. 8.4dkh cal 420 mag 1330ppm.
Nit .50 phos .07 which is where they have sat for the last 3 months.
I do two water changes a week about 15% each time...
I have only had two small changes happen. My ato stopped work so daily I top off my water.
And my tank temp has gone up. It normally sat at 78.8 and now sits at 80.3
I think its time I do one large water change like 50%. Hopefully it stops I really dont want to lose any corals

But more seriously, the best thing you can do is if you catch STN or RTN, frag off the dying portion, and if it continues frag the entire piece and spread them out to try and save some, Sometimes this isn't possible, I'v had multi branch frags go on me overnight. But stable parameters are your best bet.

I would think that fragging an acro that is STN would just upset/shock it even further..... wouldnt it be better to just leave it be? I have tried it both ways, with success both ways so im not sure which way is the better alternative.

Anytime I leave an STNing sps alone it usually goes, this may be different on larger colonies though, I'v only had success with fragging, but every bodies different!

Gotta have that acro
Could be red bugs flatworm a lot of things will attack fresh fraged corals lil star fish like the white ones but with black on them I've seen hermet crab's pick at fresh cut coral's and always could be alk and temp swings and many more

We are in the process of creating a product that stops it along with other bacterial and fungal infections. We have been working on it for nearly 2 years. We are still doing tests but at this point its 100 percent effective. Hopefully by next year it will be released on the market along with another product.

Yes it is. We are getting near so I figured I would let some of you guys know. The next step will be hobbyist trying the product before marketing it. We will as for photos of infected coral and then send the product out as a sample and allow the hobbyist to give us updates.
