 Hi  Friends,
 
 Has  anybody  used  Activated  carbon  as  a  de-chlorination  filter.  I  happen  to  read  in  Internet  that  Activated  carbon  does  absorb  the  chlorine  in  the  water.  So  was  thinking  if  we  could  use  it  as  a  filter  to  de-chlorinate  the  tap  water.  No  hastle  in  getting  the  chemicals  from  the  LFS  and  chemical  shops!!
 
 But  again  the  cost  of  the  activated  carbon  and  the  frequency  of  its  replacement.  Articles  says  that  after  some  time,  the  activated  carbon  will  not  absorb  anything  as  the  in  time  the  absorbed  organic  chemicals  will  be  bonded  with  the  carbon  and  it  will  no  longer  bond  any  more  chemicals.  Hence  we  need  to  replace  the  activated  carbon  frequently.  
 
 Please  throw  some  lights  on  this...  If  anybody  have  used  this  extensively..   Smile

 Yes,  I  too  have  read  that  activated  carbon  can  be  used  to  remove  chlorine.  And  same  thing  when  it  comes  to  replacement.
 
 I  am  not  sure  but  Beta  uses  something  for  de-chlorination.  I  guess  it  might  be  activated  carbon.
 
 But  do  you  plan  to  use  it  in  a  canister?  this  might  not  be  a  good  idea  (that  too  if  its  for  a  planted  tank).

 I  used  to  do  this  Shelly  when  I  was  maintaining  Discus  but  I  used  to  fill  my  drum  with  tap  water  and  then  run  carbon  filled  power  filter  the  whole  night.  Carbon  was  replaced  every  week.  Water  quality  was  indeed  pristine  and  safe  from  various  chemicals  I  guess.

 Hey  Shelly  
 
 I  have  also  read  this  on  the  net.
 
 But  i  encountered  the  issue  when  it  came  to  replace  the  activated  carbon.
 
 For  proper  functionality  it  may  be  required  for  you  to  replace  it  almost  after  2/3  water  changes.  
 Now  replacing  it  every  2-3  weeks  the  coasting  was  tooooo  high  so  stopped  it.

 Shelly,  as  far  as  I  have  read,  activated  carbon  is  not  a  easy  medium  to  use  -  for  that  matter,  any  chemical  filters.   It  also  removes  lots  of  trace  elements  from  water  thus  making  not  very  suitable  for  planted  aquariums  (esp.  so,  if  you  use  fertilizers).
 
 The  main  purpose  of  activated  carbon  is  said  to  be  at  the  very  beginning  of  the  setup,  to  'polish'  water  and  give  it  a  pristine  appearance.   so  most  advice  not  to  use  activated  carbon  for  filtration  in  well  matured  tank.
 
 And  of  course,  the  frequent  replacement  also  is  a  deterent.   And  I  have  never  read  that  it  could  be  used  on  its  own  for  dechlorination.

 Activated  Carbon  absorbs  only  Organic  Compounds  and  not  the  in-organic  compounds.  It  absorbs  only  the  chemicals  which  has  Carbon  atom.  
 
 All  the  chemicals  that  we  use  as  a  fertilizer  falls  under  in-organic  chemicals!!!
 
 So  I  dont  think  that  activated  carbon  will  absorb  the  fertilizers  that  we  dose  in  the  tank!!!   
 
 Please  see  the  list  on  in-organic  compounds  in  this  list:  http://en.wikipedia.org/wiki/List_of_inorganic_compounds
 
 A  note  from  Internet  "Activated  charcoal  is  good  at  trapping  other  carbon-based  impurities  ("organic"  chemicals),  as  well  as  things  like  chlorine.  Many  other  chemicals  are  not  attracted  to  carbon  at  all  --  sodium,  nitrates,  etc.  --  so  they  pass  right  through.  This  means  that  an  activated  charcoal  filter  will  remove  certain  impurities  while  ignoring  others.  It  also  means  that,  once  all  of  the  bonding  sites  are  filled,  an  activated  charcoal  filter  stops  working.  At  that  point  you  must  replace  the  filter."

 I  use  a  tap  water  purifier  for  my  fishroom  but  then  I  also  age  the  water.  Never  had  any  chlorine  related  problems  in  my  fishroom.

 Hi  Shelly,
                              I  normally  do  not  face  this  problem  but  some  time  we  get  chlorine  in  water  when  the  tank  is  cleaned  (  watchman  adds  bleaching  powder  in  tank)  last  week  I  had  this  issue  and  I  took  aerator  and  bubbled  air  through  water  for  24  hours.  I  was  not  sure  if  every  thing  had  gone  but  I  did  not  see  any  death  when  I  pored  it  to  my  neon  tank  for  30%  water  change.  As  neons  are  very  susceptible  to  chlorine  I  believe  the  burbling  worked  to  some  extend  though  it  is  said  it  is  not  a  fool  proof  method

 Two  useful  links  about  AC  and  Chlorine  reaction:
 http://www.lenntech.com/library/adsorption/adsorption.htm
 http://www.tigg.com/what-is-activated-carbon.html
 
 It  is  clear  that  activated  carbon  can  be  used  for  chlorine  removal.

 My  Friends  Yes  It  is  true  that  Activated  carbon  can  attract  any  chemical  substance  which  pass  through  it
 because  of  it  holding  capacity  which   is  ten  times  of  its  size.  if  Tap  water  is  Passed  through  Activated  carbon
 it  will  Abjorb  the  Chlorine  Of  the  water.  so  Friend  Before  using  tap  water  please  run  through  Activated  carbon.
 Cheers...But  try  to  change  the  candle  once  in  a  month...iam  doing  the  same  in  my  Discus  Hatchery.

 Thanks  shelly  for  bringing  this  topic  up,     i  was  having  chlorine  issues  since  long  and  this  time  by  mistake  chlorine  water  got  added  to  my  shrimp  tank  (  well  water  finished  and  the  watchman  filled  corporation  water  in  overhead  tank  in  my  building)  i  didnt  know  and  all  were  almost  dying  until  i  took  them  out  and  placed  them  in  packaged  water,  also  had  to  sell  most  of  them  since  not  able  to  accomodate.  This  way  i  got  to  redo  2  tanks  which  was  setup  a  year  ago,  and  were  filled  with  RCS,rainbow,  snow  white  and  their  fries.
 
 Anyway,  i  am  diverting  from  the  topic.My  query  was  .......  Does  anyone  know  where  we  can  purchase  Activated  carbon  in  bangalore   ,  if  yes  please  let  me  know  with  the  address  or  location,it  would  be  great  help.  i  have  searched  many  location  with  a  common  answer  "  come  next  week  we  will  have  stock"   Smile  .
 
 
 Thanks  in  Advance

 AC  Chamber  filter  should  be  available  with  any  water  purifier  companies.  You  can  check  with  the  local  water  purifier  companies  rather  than  looking  for  the  branded  companies  (AquaGuard,  Kent  etc).
 
 Check  the  local  water  purifier  companies  in  justdial/sulekha  and  call  them  up  and  ask  for  the  AC  filter  chamber.
