IMHO activated carbon (which is chemical filtration) should not be introduced into a filtration process except under anomalous conditions which occur very, very infrequently whether the tank is or is not planted.
Activated carbon filtration is not appropriate for a planted tank as the various elements and compounds which constitute liquid fertilizers will be substantially removed by this chemical filtration.
Plant nutrients and required catalystic trace elements which may become available in the tank water for "whatever reason" will also be removed by the activated carbon filtration.
