Hi, my tank has been up and running for 32 days now with 2 silver dollars and 2 angelfish from the start, and my ammonia numbers are still high. ammonia=8 ppm nitrates=0 nitrites=0 hardness=75 alkalinity=80 Ph=7.2 Why is there so much ammonia yet? PS: its a 55 gallon tank.Also the tank water is the clearest its been since setup and the fish seem really healthy.Just want to add more fish ,but im scared to, because of the high ammonia. Any help? Thanks Alot!!
