I feel so bad - I'm just stressing my poor little fellow out by trying to get him better. After his third dose of bacti-bath, I noticed him swimming rapidly and flashing, and he was twitchy and scared and had no appetite. He was due a massive (50 to 75 percent) water change, anyway, so I did that and tested the water. No nitrites, nitrates, I think, pretty low, but his ammonia was sky high at 2 ppm. The poor little guy - no wonder he was so unhappy. It was down below 1ppm after the change, and he's getting about another 30-40 percent change today. I also added two tablespooons of salt, and will add another two today in case the nitrite spikes, and I added a double dose of prime because it's supposed to neutralize ammonia.
So here's the question. *Does* prime actually prevent damage from ammonia? If so, how much per gallon should I use? And will it allow the tank to recycle normally? If not, what should I use instead?
I feel awful that I've hurt Gilbert by trying to cure him. His symptoms always improve on the antibiotics and get worse again once they've left the water, but at this point, it seems the antibiotics are poisoning him and may be worse than the disease.
Anyway, he was calmer this morning, and hungry again, which was a relief. But I hate to think I may have damaged him permanently.

Please advise - what can I do to neutralize the ammonia and still let the tank cycle again.
