Aquarium fish are affected by toxins coming from chlorine in the water. An excess of ammonia excreted from their own body also can cause problems. Fish will excrete ammonia waste into the water through their gills. In a healthy aquarium, the ammonia level should be at zero. If the filter is not eliminating all of the ammonia, the water may need to be treated.
 

causes of excessive ammonia in aquarium water

  • A new tank has not given the beneficial bacteria enough time to get established.
  • There are too many fish in the aquarium, or they are too large for the tank.
  • The fish are being overfed.
  • Bacteria have been killed off by a water change or different chemistry.
  • Poor filtration.
