No experience with that Antibiotic(AB), as long as it targets gram positive bacteria, it should be fine I would think.
For AB treatments, I typically do a large water change, run lights/CO2/redose etc used EM for days 1, then water change at day 3, followed by another dose.
Wait another 2-3 days, water change and then keep up on dosing thereafter, particularly good KNO3 and water changes/cleaning etc of filters.
Never comes back if you keep on top of things.
You can correct the root causes, but often that alone does not kill what is already there.
So a BO for 3 days, EM etc, is used to kill what is there.........plus the long term correction(low NO3/dirty filters etc).
Green water is similar.
