Hey guys so I'm doing a fishless cycle using nutrafin cycle. So last it finally got to the point where ammonia was eoter 0 or .25 and nitrites were 0 and nitrates were either 10 or 20 ppm. That was 2 days same results and on the next day the ammonia and nitrates were the same but the nitrates disappeared. Still saying all are 0. No plants in tank. I did notice a few baby pest snails have hatched and are roaming free. Is this the cause of disapearing nitrates or something thatll hurt my fish? Is the water safe to add him?
