I just tested my water straight from the tap without treating it. It said the chlorine was 0 but the ammonia was 1.0. Its hard water with a pH of 7.2 and a KH of 80 ppm. What does this mean? Should I use dechlorinator on it? So far I have been using straight RO water without adding anything to it except dosing ferts for the plants. I have learned that that is not good for freshwater fish. What should I do now? I'm so confused.
