Can someone please elaborate more on vibrio ? Never read this before.

It is a gram-negative bacterium that is allegedly linked to the white plague, band and other diseases as it relates to some corals.

Ok how is it cured?

I am not sure that there is a need.
In my brief research, when I was having issues, there is not a document occurrence of the white plague in captivity, furthermore they also found the bacteria in healthy colonies.
I did take back up frags of everything and did a full tank antibiotic treatment. The resolution for me in the end was as simple as bringing my nutrients up which
I should mention a big thanks to sirreal63 for his guidance during the event.

Thanks once more for the responses, I think I'm getting a good mental picture of the environmental causes:
ALK swings or higher levels often in a low nutrient environment with a possible contribution from stress & instability during the coral's chain of custody before it gets into out tanks. Animal & bacteria parasites are not really the cause. Higher or lower salinity from uncalibrated refractometers is also a suspected comfributor. Iodide dips will not help and may compound the condition. Fragging away still healthy portions of the colony right after discovery is really the only known defence.
Does that sound line a reasonable summary of what is known about this condition.?

Great post Tek & thanks for the STN vs RTN clarification. I chose R (rapid) because it sure seemed to come on fast to me!
My ORA green with blue tip acro got it too. I've fragged that & 3 of the 4 frags are doing fine one day after fraging. The Tabling Acro may be stabilizing but only time will tell. The pink Sertosa I bought at the same time looks perfect thankfully.
When I acclimated these corals I set aside the LFS water for testing ALK & Ca but forgot to do it. The LFS salinity was 1.024 vs my level of 1.026.
Since nutrient poor tanks are often blamed I was wondering if a dip in water rich with organics like an addition of Marine Snow or Amino Acid product to the acclimation container and then small scale dosing of the display tank for a short period might give new corals a slight defense against RTN/STN? I can't see it being dangerous.... Probably a dumb idea but I'm just sleculating.
I was just finishing dosing 20ppm Mg per day to correct a 1080 ppm level up into the 1300s when I introduced the corals I'm talking about. Now im wondering if important levels like ALK could have been in a flux because of recent Mg dosing & imjust missed it? I thought my ALK was stable at roughly 7.8 dKH or so with variations of perhaps swings of .7 or .8 below and above this number from time to time. I didn't test at the same time of day and my doser adds 1dKH (40ml to ~60g of SW) of ALK per day over 3 doses 8 hours apart. Ca dosing is done in a different part of the tank and at different times. Is this considered ALK STABLE? I always thought a tight range was the key as opposed to sticking to a single rock solid value. Can anyone comment on this?
