I want to know how to see if my tank fully cycled.
Thank you @essjay you always give me some advice about cycling.You can add bottled bacteria to a tank with fish.
But the only way to know when a cycle is complete is by testing for ammonia and nitrite. If they are zero after a day with fish in the tank or adding ammonia during a fishless cycle, the cycle is complete. If they are not zero, the cycle is not complete.
