 I  was  doing  some  research  regarding  those  CO2  Tablets  available  in  the  market.  I  used  to  wonder  what  the  hell  it  is  composed  of  to  cost  so  much  (  Rs.350  for  a  brand  ,  but  I  will  not  disclose  the  brand  name  ).  For  research  purpose  ,  I  finally  got  one  of  them.  
 
 I  took  a  glass  of  water  and  observed  the  reaction.
 
 The  gas  evolved  like  '  effervescent  '.  It  seemed  so  much  similar  to  the  reaction  of  Dispirin  tablet  in  a  glass  of  water.
 
 Soon  ,  I  opened  the  net  and  after  a  bit  of  search  I  found  that  Aspirin  (  or  Dispirin  )  when  dropped  in  a  glass  of  water  produces  a  lot  of  Carbon  di  oxide.
 
 Aspirin  or  Dispirin  is  actually  acetylsalicylic  acid  and  nothing  else.  I  also  found  a  practical  experiment  regarding  the  same  ,  that  shares  the  same  logic  :
 
 http://www.doitscience.com/tag/carbon-dioxide-gas/  
 
 So  any  interested  folks  out  there  who  would  help  me  in  the  research  to  fix  the  dosage  ?
 
 Any  suggestion  ,  comments  are  welcomed  !

 WOW  now  the  fish  will  no  longer  have  Headaches  or  fever  !!!  woohoo!!   Cheer   ...  Just  kidding.  
 
 Thats  a  good  find  there  buddy.  Lets  hope  someone  can  join  your  research  ..I'll  also  try  the  same  at  my  end  and  see  if  i  can  figure  something  out.

 On  Second  thoughts,  Rather  than  dosing  it  to  a  tank,  can  this  be  used  in  a  DIY  Co2  instead  of  the  Yeast  and  sugar  method.  I  am  not  sure  though  how  much  pressure  would  build  up.  But  if  we  can  hold  the  pressure  in  a  can,  then  this  could  be  an  alternate  to  our  DIY  Co2.  Let  me  give  it  a  shot.

 Nirav  ,  I  found  yet  another  reaction.
 
 This  site  is  a  bit  contradictory  to  my  idea  (  as  well  as  the  previous  site  I  mentioned  )  :
 
 http://72.14.235.132/search?q=cache:ONg90B8PeCQJ:www.mtps.com/8062093124152700/lib/8062093124152700/aspirinsynthesis.doc+acetylsalicylic+acid+aspirin+carbon+di+oxide&cd=5&hl=en&ct=clnk&gl=in&client=firefox-a  
 
 They  say  that  if  we  drop  a  Aspirin  tablet  to  a  water  full  test  tube  ,  along  with  a  bit  of  sodium  bicarbonate    then  a  lot  of  CO2  will  be  evolved.
 
 Nirav  ,  right  now  I  don't  have  a  test  kit  ,  I  have  a  very  old  one  that  has  expired.
 
 If  you  have  a  pH  test  kit  ,  can  you  kindly  do  the  following  and  revert  with  results  ?  :
 
 Take  2  glass  full  of  water.
 
 Let  us  name  them  glass  A  and  B.
 
 Take  the  pH  reading  of  both.
 
 Drop  a  single  Dispirin  tablet  into  A.
 
 Take  the  pH  reading  again.
 
 If  pH  drops  then  obviously  CO2  is  being  produced.  ----------------  >reading  1
 
 -------------
 
 Now  take  glass  B.
 
 Take  pH  reading.
 
 Add  a  Dispirin  tablet.  
 
 Add  some  sodium  bicarbonate  (  baking  powder  )
 
 Now  again  take  pH  reading.  
 
 If  pH  reading  decreases  ,  then  CO2  has  been  produced  .      ----------->  reading  2
 
 ----------
 
 Compare  reading  1  with  reading  2.  (  labeled  above  ).
 
 If  reading  2  is  less  (  i.e  more  pH  drop  )  than  reading  1  ,  then  sodium  bicarbonate  takes  part  in  reaction  as  a  result  of  which  more  CO2  is  produced.
 
 Please  try  this  and  revert  with  results.  Help  from  others  are  also  appreciated  and  is  highly  valuable  to  me  !  Smile

 Nirav  I  too  thought  of  using  it  instead  of  Yeast.  I  even  typed  it  ,  but  then  I  erased  it  as  I  thought  that  it  might  sound  silly  !

 Hi,
 
 Yes  i  do  have  an  digital  hanna  ph  meter  with  me...but  i  dont  have  disprin  with  me  at  this  time  ..hehe  ...will  reach  home  and  give  it  a  test  as  indicated.  However  i  am  certain  we  cannot  add  disprin  to  the  tank,  not  sure  how  it  will  react.  I  am  sure  there  are  a  lot  more  chemicals  in  it  then  just  acids,  however  the  DIY  CO2  idea  where  only  the  gas  is  let  to  reach  the  tank  suits  me  better.
 
 cheers

 We  already  have  a  thread  on  the  dangers  of  trying  to  contain  /  control  DIY  CO2,  but  lets  see  what  you  can  figure  out  abt  the  co2  alternative.

 No  ,  in  case  f  DIY  CO2  ,  the  CO2  content  in  the  bottle  continues  to  increase  till  a  certain  point.  That's  why  it  is  dangerous.
 
 But  here  CO2  will  be  liberated  almost  immediately  ,  we  will  be  just  storing  the  CO2  in   a  can.  It  will  then  be  dispersed  in  the  aquarium  with  the  help  of  a  controller.   
 
 Dispirin  contains  acetylsalicylic  acid  which  is  not  harmful  for  fish  ,  as  someone  in  the  forum  uses  2  or  3  dispirin  in  his  tank  thinking  it  will  reduce  fish  stress.
 
 But  we  can  not  add  Dispirin  to  tank.  You  are  correct.  But  the  reason  why  we   can't  add  it  to  tank  directly  is  the  sudden  pH  fall  ,  which  is  fatal.
 
 Expecting  much  more  inputs  :-)

 Only  my  research  and  experiment  will  lead  to  nothing.  You  all  need  to  participate.  Come  on  guys  ,  it's  nothing  that  harmful.  After  all  we  planted  tank  guys  play  with  gun  powder  (  KNO3  )  every  now  and  then   Very Happy

 As  per  chemistry,  when  the  concentration  of  CO2  is  more   it  should  not  decrease  the  pH  considerably.  You  may  find  diluted  as  well  as  concentrated  acid  like  HCl  (any  acid)'s  pH  in  the  range  of  3-2  only  in  the  normal  working  concentrations.

 Further  more  one  dispirin  tablet  would  be  having  mgs  of  active  ingredient   only,  which  will  give  you  very  less  CO2  only.  If  we  try  in  the  same  direction,  why  not  with  Eno's  salt  too?  The  effervescence  found  with  Eno's  salt  too  is  nothing  but  CO2.
 
 Seriously  talking,  the  amount  of  CO2  released  out  by  these  ways  would  be  instantaneous  and  a  small  quantity  only.

 I  was  thinking  that  you  will  reply  with  some  serious  post  and  you......                

 
 I  was  being  quite  serious.  An  antacid  tablet  typically  consists  of  something  like  sodium  bicarbonate,  citric  acid  and  some  binder.  Add  water  and  it  releases  CO2.
 
 Some  antacid  tabs  also  contain  small  amounts  of  aspirin,  but  this  does  not  contribute  to  the  formation  of  CO2,  AFAIK.
