My goldfish died the other day after attempts to revive her. I have since discovered what I did wrong. I have changed a quarter of the water in my 10 gallon tank with conditioned water. I have ammonia in the tank, which I suspect contributed to my fish's death. I have put "ammonia remover" in the tank but the readings are still the same. Should I start from scratch and try and cycle the tank, or can I put a product such as SafeStart in? I have read good things about this product and especially of one called BioSphere, but I don't see it for sale in Canada. I would really like to try again with a single goldfish, but am not sure if I am doing it right.
Fist the tank is too small for a goldfish. You should start with a min 20 gallon tank as it is too hard to keep the Ammonia, Nirtites and Nitrates in a 10 gallon tank.
You will go through a problem called New Tank Syndrome and have about 6 weeks of cycling. http://www.bestfish.com/breakin.html I recommend starting with a cheap feeder fish so if you loose it there is not a lot of money tied up.
To start the tank I suggest Amquel for the water as it removes Ammonia and Chlorine in the water. Next I use Bio Spira or Fritzyme #7 to help with the bacteria in the tank to help get though the cycling.
You will have to keep checking the the water parameters as do water changes throughout the cycling. I also would add one teaspoon full of Aquarium per gallon. This helps with stress on the fish as well as working on bacteria, fungal issuse and other problems you may encounter.
