I'm having a heck of time trying to figure out what to do to lower my ammonia. My water out of the sink is high, went across the street to get a sample and that is high also. The picture shows out of sink, across the street, and my aquarium water. My nitrite is like 0 and my nitrate is about 5ppm. Since the ammonia out of the sink is high doing a water change isn't going to help. Does anyone else have high ammonia in the city water causing this? Trying to figure out what to do. My tank was cycled then I added 10 fish, so I tested and found high ammonia. I did a water change a week after getting them and it was still high so I tested the city water and its the same. What do you guys recommend?
