Yes my tank is still cycling, but this is before the tank. My ammonia has dropped, just waiting for nitrites to drop and happen to test the barrel,
Im guessing once I start doing real water changes the water wont age as long. This water was 10ish days old.
I drained the barrel and refilled it measures 0 now. I will monitor daily to see if it goes up. I just didn't think there was anything to produce nitrites in tap water.
I was just shocked that the water had anything in it.
Edit - There was no chlorine or chloramine in the water after the filter while filling. I checked a sample coming into barrel.
