Third time better be the charm

Thanks so much but for the 180g based on info online probably close to 100. 500mg 1/ 10g treat 3-5 days. I'm going to grab the fin and body cure. No one else is symptomatic at the moment. Thinking it may have been "saddleback disease". I should have had a med kit put together. So that's what I'm going to do now.
Yeah I thought you might need more than I had, tossed it out there anyhow.
 
Cipro dosage is 50 mg / gal QD x 7days, which can be a bit cost prohibitive for larger systems. Generally speaking, for something broad spectrum, Doxycycline will work just fine. It is sold by API as "fin and body cure

Just an FYI - all tetracyclines are strongly inhibited by Ca and Mg in the water, they really should only be used in freshwater aquariums. They also react poorly to light, so shouldn't be used in a reef tank with full lighting.

Lewbart's dose for Enrofloxacin is a lot lower than 50 mg/gal (9.5 to 19 mg/gal). I presume Cipro is similar, as some fish metabolize enro into cipro.

Thanks Jay I appreciate your help with this one. No I did the damage when I caught her in a net. The scales sloughed right off. Agree bacterial because nothing else seems to match up, or check all the boxes. Hopefully a dose of Rally to the system will knock it back and prevent any more damage.

Rally has acriflavine in it, but my understanding is that the amount is very low so as not to cause issues in display tanks.

External bacterial infections usually don't spread widely unless the other fish have skin injuries. If it does spread, a broad spectrum, gram negative antibiotic would be the best option (typically dosed in a treatment tank though). I often use Neomycin, but a number of people here suggest Kanamycin.

I agree with the inhibition caused by Ca and Mg, however dosage rates in SW generally account for this (as with humans). Additionally, the UV degradation of doxy takes about 24 hrs, which is generally when it's time to dose again. That degradation is, in my opinion, an advantage over flouroquinalone treatment given the disposal of the water, post treatment. However, one could argue that factory farming's use of Cipro is far more damaging than that of reef hobbyists, but I digress.

While also a flouroquinalone, I'm not sure that Baytril would be my first go-to as an alternative to Cipro, despite its use in aquaria for decades. For note, Cipro is not usually my first treatment choice either, unless treating nems. This, in addition to the aforementioned lack of UV degradation, is also based on availability. In this case, for both spectrum and cost, I would likely substitute Neomycin.

Now, all that being said, you are undoubtedly the foremost authority on this, and I mean no disrespect at all. You have certainly forgotten more than I'll ever know, and that's for sure. My medical background just lends to a different approach.

My anxiety is already through the roof so why not crank it up a notch.

I thought the Cipro dosage was 0.5mg/gallon... ?

Here’s a link to a R2R thread on cipro dosing . Helped me.

Yes, and per these instructions, a 500mg pill/capsule will treat 1000 gallons per dose.
 
What do the rest of the instructions say? Is the 10 gallons of water the solution you then use to dose the tank? I doubt they are saying to dose 5000mg to 100 gallon tank...
Ok, I've been looking at in tank coral treatments... Maybe fish treatment is a higher dose.

Again, Cipro is not my go-to first line treatment for a number of different reasons, and I generally do not ever reccomend dosing antibiotics directly into a DT unless it is an absolute emergency. The exception being when treating Heteractis sp. For V. vulnificus auto innoculation. That being said, the dose is the dose in SW, regardless of the critter.
