Tropical fish in tank dying

Why have my tropical fish died?

Do not add fish untill you have fully cycled the tank, some people will tell you to buy some hardy fish to do this but I find this cruel to the poor fish, get a bottle of ammonia and a master test kit like the API test kit for example and a medicine dropper.

Fill the tank with declorinated water and whatever decorations you wish to have, turn on the filter and turn the heater up as high as it will go, mine was in the mid 80's, do a base reading on the water for Amonia, Nitrites, Nitrates and PH and note them down, then add amonia untill you get a reading of 4-5ppm on the test kit and note how much it took to do this.

Test daily to see what the ammonia reading is. There is no use to test for anything else. Nitrite and nitrate won't be present until some ammonia has processed. Ammonia will raise your pH so no use to test it either. Once you see a drop in the ammonia, test for nitrite. There should be some present. When the ammonia drops back to about near zero (usually takes about a week), add enough to raise it back to about 3 to 4 ppm and begin testing the nitrite daily.

Every time the ammonia drops back to zero, raise it back up to 3 to 4 ppm and continue to check nitrites. The nitrite reading will go off the chart. Once the ammonia is dropping from around 4 ppm back to zero in 12 hours or less you have sufficient bacteria to handle the ammonia your fish load produces. Continue to add ammonia daily as you must feed the bacteria that have formed or they will begin to die off.

The nitrite spike will generally take about twice as long to drop to zero as did the ammonia spike. The reason for this is two-fold. First, the nitrite processing bacteria just develop slower than those that process ammonia. Second, you are adding more nitrite daily (every time you add ammonia, it is transformed into nitrite raising the level a little more) as opposed to the ammonia, which you only add once at the start and then waited on it to drop to zero. During this time, you should occasionally test for nitrate too. The presence of nitrate means that nitrite is being processed, completing the nitrogen cycle. The nitrate level will also go off the chart but you will take care of that with a large water change later. It will seem like forever before the nitrite finally falls back to zero but eventually, almost overnight, it will drop and you can celebrate. You are almost there. Once the bacteria are able to process 4 or 5 ppm of ammonia back to zero ammonia and nitrite in about 10 to 12 hours. You are officially cycled.
