What would you recommend using as a precautionary QT medication?
I match salinity in QT to arriving fish or make sure it's a touch lower (Usually 1.018).
Acclimate (float for 30-45min in bag and release) fish directly into 1.0ppm copper (copper power) upon arrival. This is much safer than drip acclimation and removes the possibility of ammonia exposure during acclimation.
I start fish off on food soaked general cure + Focus day one (continue for 14 days).
Then I spend the next three days raising cu level to 1.75ppm.
At this point I am watching very closely for external symptoms of bacterial infections. If one arises or a fish prone to infection stops eating then I dose Spectogram (Kanamycin+Nitrofurazone) and continue throughout copper. You can also use Kanaplex+furan-2. The WCs are fun maintaining the therapeutic Cu level. But once you have the hang of it, it's not bad. Copper has to be pre-dosed into new SW prior to adding to tank to keep Cu level from dropping below therapeutic.
Keep in mind ABX are slow to work on fish. They are likely to be even slower in the presence of copper due to the weakened immune system. So the Spectogram IME has always prevented infection from worsening. Some have healed. I do also keep Sulfaplex and Neoplex handy for certain types of infections. They are safe to use with copper.
After 14 days of therapeutic copper I transfer to a 2nd sterile QT. Temp/salinity matching.
After the transfer if I have a fish that is still showing signs of infection I would run a 14 day course of NFG. If no signs of infection is present I would skip NFG.
Last step is two rounds of Praziquantel using either GC or Prazipro. I prefer GC as it contains metronidazole as well and covers a few other diseases like Brook and uronema.
14 Days of observation post medications prior to transfer to DT in order to make sure the fish are healthy and disease free.
This is a very aggressive approach. I can tell you though I have improved my success rate significantly since adapting to this method.
After the Hanna checker discovery I was getting fish through copper without much issue, but using the same tank and treating for 30 days I was losing fish in the 20-30 day range to bacterial infection. So now using multiple tanks and reducing the copper exposure time along with having the proper ABX to be used with/without copper it is what worked best for me. We are still working on tweaking it a bit. Most of this system was designed/adapted with much help of

I also preform FW dips if I see a fish scratching in copper (After 7 days at the therapeutic level). If a fish arrives with velvet/velvet symptoms they get a FW dip as well as a 90 min Ruby Reef rally bath.
