i just setup a new fish tank, 75 gallong with an aqua clear 110... ive used the declorinater treatment on it, let my filter run on it for 2 days, added water from my established tank into it, shrimp to establish some waste,and a product with lots of beneficial bacteria in it to help cylce the tank.. Than i tested my ammonia its a 0 ppm. So i put my two feeder gold fish in it to see if they would be ok and they have been fine for 2 days now. Im not sure but i think the cycle could be completed, is this possible?
