Hi Carlos,
Thanks for responding. I did at least 2 water changes after the tetracycline treatment. One of about 50% and the other of about 20%.
I thought it was a bacterial infection from reading various online forums that talked about ADF having the same symptoms and the people were told it was most likely a bacterial infection.
I didn't want to wait too long to treat the tank because the info on the forums stated that the frogs with these symptoms, when left untreated, died within days of the symptoms appearing.
Based on the tetracycline and maracyn 2 labels, neither is supposed to affect the biological filter.
The AmmoLock label claims that the ammonia is simply converted to a non toxic form. Online articles have stated that the bacteria will feed on this form and convert it to nitrites the way they would with the toxic form of ammonia.
I will continue with the maracyn 2 treatment, which is 5 days, and pray that all goes well.
I am attempting to cycle water in separate empty tanks using ammonia AND Cycle bacteria but the process is taking much longer than I thought. I assumed that adding Cycle to the water containing ammonia would spped things up but that does't appear to be the case. I am waiting for this water to be ready so I can do a large water change using cycled water instead of using conditioned tap water after treatment.
