So I recently had to treat my tank for Columnaris with some bacteria killing Kanaplex. The good news is it saved my fish. No signs of it for almost two weeks. The bad news is I lost my cycle. Ammonia will go to 1.0. I do a water change, dose tank with prime and it reduces to .25-.50. The prime is effective for 48 hours. I test again and I'm back up to 1.0. I've repeated that 3 times and keep getting the same results. My dilemma is do I keep doing this until I'm cycled or is the prime every few days killing bacteria? Can I add Tetra Safe Start or Secham Stability after 48 hours dosing Prime to see if that bacteria will eat the ammonia or will my fish get sick? I've never had to recycle the tank. It's full of fish. Thanks in advance.
