 and  i  am  currently  having  difficulty  in  the  difference  between  normal  charcoal  or  activated  carbon  used  in  filters
 
 and  can  i  use  normal  charcoal  in  my  filter  
 and  if  yes  how  do  i  process  it  
 
 
 please  help

 Hi  Sergio,
 Activated  carbon  is  treated  with  oxygen  and  some  other  chemical  process  which  result  in  making  it  very  very  porous.  Because  of  this  porosity,  the  effective  surface  area  increases  many  folds  some  times  even  thousand  times  when  compared  to  normal  carbon..  and  since  the  surface  area  is  more  the  filtration  capacity  increases  in  direct  proportion..  simply  because  there  is  more  surface  area  for  the  beneficial  bacteria  to  colonize.  More  over,  generally  it  absorbs  most  of  the  chemicals  directly  before  turning  itself  into  a  bio  media  in  a  filter.

 Acitvated  charcoal  is  available  with  water  filter  purifier  firms,  it  is  also  available  at  many  shops  that  supply  lab  chemicals  to  colleges.
 It  is  also  online  at  aquabynature.com

 Nidhi,  thanks  for  the  explanation.
 
 Serigo,  Just  be  aware  that  the  activated  carbon  has  limited  life,  most  filter  manufacturer  recommend  to  change  the  carbon  in  3-6  month  depending  on  your  bio-load.
 
 i  have  never  changed  my  carbon  of  my  canister  filter  in  last  4  year  and  it  still  works  (  my  tank  is  healthy  and  that's  what  i  am  looking  for)
 
 Good  luck

 yes,  can  be  used..  even  activated  charcoal  is  being  used  as  top  layer  for  getting  the  dark  contrast  in  planted  tanks,  and  are  good  for  the  plants  also..  because  they  absorb  nutrition  and  is  available  for  plants  to  consume.

 Techikhan,  The  chemical  filtration  life  of  the  activated  carbon  is  less  as  mentioned  by  Deepak,  but  after  that  period  it  starts  to  act  as  a  very  good  biological  media  in  filtration.

 What  advantage  do  you  see  by  doing  this?
 I  have  come  not  across  people  using  charcoal  in  substrates.

 i  use  ordinary  charcoal  from  days  in  my  filters..i  just  wash  them  once  in  salt  water  and  use  it.  i  find  them  helpful.

 effectiveness  of  carbon  ceases  after  couple  of  months.
 corbon  is  not  recomended  in  planted  aquaria  as  it  aborbs  nutrients.
 further  prolonged  use  of  same  corbon  media  for  long  time  can  release  toxins.

 @  Emmannuel,
 "effectiveness  of  carbon  ceases  after  couple  of  months."
 Were  are  not  worried  about  the  chemical  filtration  effectiveness,  but  the  biological  filtration.
 "corbon  is  not  recomended  in  planted  aquaria  as  it  aborbs  nutrients."
 If  your  first  point  is  true,  then  this  point  is  false  (after  couple  of  months)..
 "further  prolonged  use  of  same  corbon  media  for  long  time  can  release  toxins."
 And,  this  theory  might  be  correct  when  it  comes  to  its  use  as  media  in  RO  water  filters  used  for  our  consumption,  But  its  not  proven  in  aquarium  conditions..
 I  would  be  happy  to  see  any  reference  or  links  from  which  you  got  this  info..
 Because,  I  am  about  to  use  as  substrate  in  one  of  My  tanks..  so  if  you  are  right,  I  may  have  to  find  other  options..
 Thanks..

 Active  carbon  as  substrated  is  possible  in  a  non  planted  tank.  after  it  has  become  passive,  it  will  work  as  a  bacteria  colony  housing  Smile  .  But  in  a  planted  tank  it  will  only  serve  as  a  top  substrate  like  chips.

 Nidhi  I  dont  have  suitable  reference  now  ,  this  link  may  give  you  some  more  details.
 Filters  makers  like  Ehiem  suggests  not  to  over  use  carbon  pads  which  comes  with  theirs  canister.
 carbon  media  in  planted  aquaria  is  waste  of  resources  as  it  will  absorb  trace  elements  during  its  initial  months.
 
 possible  reference
