Would help a lot to know what filter you have; my best guess is that there is a fibrous material and it is heavily stained - this would then be your good bacteria. Place this in your new filter with the form :11: If you do not have room for it, then use a section of it and then rinse the old filter material into the tank water - this wil lfurther seed the new foam.
