I agree with all statements and don’t take the use of any antibiotic, not just in the hobby, lightly. I have tried to keep things as consistent as possible (parameters, flow, lighting, water changes etc). This truly is a Hail Mary at stopping this downhill swing for the tank.
Other than coral additions the only other changes include:
- 11/24 added 2” yellow candy hogfish, which I haven’t seen pick on any corals
- 12/3 swapped out 10lbs of Marco rock for 25lbs Carib-sea life rock (connected tank)
- 12/17 added small Redfin Fairy Wrasse and one small Bimac Anthias
