Ammonia is naturally produced in aquariums as a byproduct of waste produced from your livestock. It is a natural part of the Nitrogen Cycle that maintains balance in a healthy aquarium. When too much ammonia accumulates in the aquarium, ammonia toxicity can occur and seriously affect the health of your tank inhabitants, even leading to death. Therefore, it is crucial to monitor ammonia levels to ensure they remain steady and low.

Will copper power in a QT tank give inaccurate test results? I have a QT running and did two tests back to back and I am getting 0.55 ppm of ammonia with a copper level around 2.0 ppm.

Hey there! Yes, copper can give a false positive ammonia reading.
