we should not be using antibiotics/cipro for the reasons mentioned copiously in the thread up till now. using pro biotics/sounds great. don't keep anemones if you can't do it without cipro. I wouldn't ever need it to keep anems. its a lazy approach that is harmful, for reasons covered, and use of cipro stifles innovation that reefers would be driven to find were they not given 20 workarounds via online pill mills. there is no way "they'd die" without cipro, that's not a reef tank article. ocean articles don't apply to reef tanks especially in this sense, just like the copious ocean substrate articles don't apply to reef tank sandbeds.
How do you know this? I've had firsthand experience with this. My corals were dying right in front of me, and my Aquabiomics tests revealed a high level of Oceanospirillales bacteria, which Acropora with RTN had in the link I provided some time ago.
This isn't directed at you, but I hear it all the time when these treatments are mentioned. "We didn't need this back in the day." The entire "back in the day" approach no longer works. Back in the day, "corals in the ocean were not wasting away like they are now. Acting as if a bad bacteria or pathogen could not be transmitted to our tanks from the ocean now, with all of the basement importers, bottled bacteria, etc is foolish. In the last five years, I have never seen as many cases of RTN or STN in tanks as I have now. Why is this so? Many will point to dry rocks, but I believe it is more due to the introduction of bad bacteria and pathogens before the good biome can establish itself. How are they being introduced? It could be from mariculture corals or from the popular trend of dumping bottled mystery bacteria into our tanks.
I agree that Cipro should not be used as a first-line treatment for RTN or STN because other factors may be involved. I watched my coral deteriorate for months before starting Cipro. I followed the steps and sent a sample to Aquabiomics before dosing. Cipro, I believe, can be a valuable tool when used correctly. Instead of telling everyone not to use it, perhaps we should teach them how to use it properly and responsibly.
I also believe that using Cipro as a dip is a bad idea because most people will not dispose of it properly. Dumping it down the drain could have a negative impact. However, I see nothing wrong with an in-tank treatment. When Cipro is exposed to UV and light, it degrades. Where is the problem if someone waits a couple of weeks after treatment to do a water change, etc.? By then the antibiotic should be inert.
