Is it possible to swap out external filter without reusing media from old filter on a planted tank with fishes thats around 6 weeks old?
Some of the fish are 2 weeks old.
I've done some reading and the recommendation is to either run 2 filters side-by-side for a month or re-use the media from old filter. However if I do get a new one the media will not be compatible.
