Yes, the lock man is right: in a larger tank, the ammonia and nitrite concentrations should be lower with the same number of fish, so it would be "safer" and potentially less work for lauJust wanted to say, if Lau went with a fishless cycle for a new tank, he/she would still need to be doing fish-in water changes on the biorb anyway, so, IMO, it would probably be better to put the fish in the larger tank sooner rather than later.
I'll get them transferred over tonight, hopefully no more dying fish!
Great, your advice has been very much appreciated.
