I ahve the standard Whipser HOB filter and have been using the filters
with carbon.. I recently discovered a site that said you should remove
the carbon to keep beneficial bacteria going through the filter...

Is this true?
=====================
I haven't used carbon in years. The bacteria don't go through the filter,
they cling to whatever they can attach themselves to all over the tank,
including whatever is in the filter.
