Hello, My tank has been set up for 2 weeks now and I was attempting to do a fishless cycle so I added 2ppm of ammonia (no sign of surfactants or scents ). I did an ammonia test today and its still about the same color of green that it was when i started... I tried some tetra safe start I wasnt counting on it but even without it I would have expected some change by now.... what should I do? Maybe my ammonia actually is bad? Should I just restart.. Any help is appreciated
