I just finished medicating my tank (6 Gallon Eclipse system with biofilter) with tetracycline. I did as the directions recommended: One capsule, 24hrs later another capsule, 24 hrs later 25% water change and another capsule, 24hrs later the last capsule. The manufacturer said that it would not affect the bioload.
24 hrs later, I did a 30%water change and replaced the filter pack using extra carbon to get rid of the meds.
I just tested the water, and have:
no ammonia
no nitrites
pH 7.0
These were actually the values before and after adding the medication
BUT:
Now I have NO Nitrates also. Before I added the tetracycline, I had between 10-20ppm of nitrates, and now have 0ppm. Is this conclusive of killing off all the biological stuff in the tank???
I know most of you would say- great values--- but I was just wondering if the tetracycline actually could have killed off the bioload?
