ok so i got a 10 gallon starter kit. had some feeder goldies in there (pet store lady was trying to get me to cycle the tank with them) ok so ammonia spiked, gold fish died off one by one. (she didnt tell me this was going to happen) anywho i had a tank with the exact same filter and its established wonderfully. i took the filter out of the cycled tank and placed it in the new tank. this was a week after initial setup. 3 days later, ammonia is zero nitrites is zero. is my tank really cycled? i dont have a nitrate test yet. it will be here soon. so either its done or i did something and its back at square one. the pet store said if ammonia is zero for 3 days and nitrites are zero its cycled. last thing i wanna do is stock it and lose everything. please any help or advice would be appreciated
