would the cyclind process be quicker if i ran the new filter in an old tank (along another fillter) for a few weeks before i put it in the new tank?
does it work
yes it would work. if you mean have 2 filters in your current tank then yes. it would mean the new filter that will be going into the new tank starts to build up some 'good' bacteria and therefore begins to cycle. however you would need to do this for a few weeks (5 or 6)
