After removing filter baskets from pre-existing established cannister, bottom gunk = mulm which can be poured into new sustrate, to seed new tank.
But what about filter sponges, etc. Can you/is it advisable to simply squish pre-existing filter sponges into water column of new tank? Of course there are nitrifying (and other) bacteria there too, but is it "OK" to squish all that gunk into new tank?
thanks,
