I'm still waiting for the ammonia levels to go down, it's been a week and still at 4ppm. But the water turned green. Is this normal while it's doing the cycle? I followed how to start the thing going, filter media from other tank,decorations and I added food, bubble thing is going and the heat is at 77.2F. Is there something I missed or do I need more patience? I call the company and the person assured me that it was only ammonia and no other stuff.
