Last 3 times I added ammonia, I added enough to get the tank to 4ppm, and every time 48hrs later ammonia and nitrites were back at 0. Last time nitrites were at 0, nitrate test showed 50ppm. Is it safe You need to do partial water change during fishless cycling only when the ammonia levels in your tank exceed above 4 PPM. Ammonia level above 4 PPM is toxic for the beneficial bacteria and it can stop the cycle.
