i keep adding ammonia, about 2ppm, to my tank to cycle it. every day the level goes down to about .5ppm, but there is no sign of nitrite or nitrate. i dont understand what is going on. i could see if the tank had cycled that it would do this but the ammonia level does not go to 0 and there are no nitrates, so i am at a loss. plz help me!!! thanks in advance.
