Hi all, I am sure that someone has posted a thread with this topic before but I haven't the time to search through the archives. I have recently purchased a betta that I have housed in a 2.5 gallon tank. Before adding my fish to the tank I put in some tap water conditioner, some ich preventative, and a product called ammonia clear. I keep a small heater in the tank to regulate tempurature, and feed my betta blood worms. During the first week the water was very cloudy but cleared up after about 5 days. I am now going into the second week and I've noticed that the water in tank has a very strong odor that resembles cat urine. I have owned cats in the past and I am very familiar with this smell. I know that ammonia is present in cat urine and it what causes it have that atrocious smell, so I am led to believe that it's ammonia causing the smell in my tank. During the first week I did a 25% water change and today I did a 50% water change. I, of course, treated the water with the aforementioned chemicals and let it sit before adding it back into the tank. Other than doing a complete water change, is there something more I can do? Is there another chemical I could put in the water, other than the one I'm using, to reduce the amount of ammonia? I am going to go do a complete water change right now because I can no longer take the smell. Any and all help will be very much appreciated.
