 Can  you  tell  me  how  much  milk  powder  you  use  for  each  batch?  I  use  a  2L  coke  bottle  filled  3/4.

 Very Happy  
 anyways,
 Doc.  lets  discuss  something  crazy  here  -  soda  (drink)  is  carbonated  water  the  bottle  label  reads  -  purified  water  and  carbon-di-oxide!
 Is  this  not  what  we  all  want?  Why  can't  we  not  use  a  soda/day  to  dose  our  tank.  (this  is  just  a  logic)
 The  soda-water  is  something  which  will  cost  you  a  Re.  10/-  note  per  day  and  for  the  money  you  will  get  maximum  co2  dissolved  water  and  the  best  part  is  it  is  easily  obtained  and  can  be  stocked!  Monthly  exps.  for  the  same  will  be  Rs.  300/month  (and  much  cheaper  if  you  have  a  soda  maker  at  home)  and  we  can  replenish  the  evapourated  water(if  you  have  a  cooling  fan)  with  purified  carbonated  water  Thumb Up  
 as  I  said  it  is  a  crazy  thought  -  think  about  it!

 hi  AS,
 guess  this  has  been  discussed  on  a  thread  before.cant  find  a  reference  to  that  thread.
 But  pls  do  check  this
 http://www.thekrib.com/Plants/CO2/soda.html
 
 Doesnt  seem  too  feasible  for  various  reasons  mentioned  in  there.

 Dont  think  it  will  be  cost  effective,  Aquascapes.  Our  Yeast  concoctions  are  cheaper  and  give  a  steady  low  rate  of  CO2  emmision  which  if  used  with  a  mixer  will  give  good  solubility  of  the  co2  in  water  -    the  soda  on  the  other  hand  will  cause  a  sudden  large  input  of  CO2  with  an  attendent  steep  fall  in  pH.  Regarding  the  minerals  mentioned  in  that  article  in  krib.com  it  may  not  be  applicable  to  our  type  of  soda.  In  western  countries  some  minerals  are  added  to  improve  the  taste.  In  fact  Perrier  even  contains  a  tiny  amount  of  quinine.
 
 If  one  wants  to  really  ensure  a  calibrated  flow  of  CO2  then  the  best  way  would  ofcourse  be  a  cylinder  with  a  flowmeter,  but  I  guess  that  can  run  upto  a  couple  of  thousand  rupees.

 Very Happy  well,  in  theory  it  sounds  interesting!  so  thought  we  should  discuss

 I  think  the  soda  maker  can  be  a  lot  cheaper
 I'm  not  talking  about  the  yeast  formula  here  (of-course  it  is  cheaper  -  but  heard  of  many  backfires)

 What  if  we  use  a  drip  system?  (of-course  I  don't  have  a  plan  for  this  but,  will  give  it  some  serious  thought).  Let  me  explain  it  this  way  -  we  have  small  quantities  of  gas  which  steadily  gets  released  in  the  tank  -  How  about  small  quantities  of  liquid  (soda)  getting  steadily  mixed  into  the  tank  -  drop  by  drop.
 The  POINT  is  -  is  the  gas  more  effective  or  the  carbonated  water?

 Yeah,  you  have  a  point-  it  isnt  actually  the  gas,  but  carbonic  acid  since
 Carbon  dioxide  is  an  acidic  oxide  and  reacts  with  water  to  give  carbonic  acid.  
 
 CO2      +      H2O      -->      H2CO3          
 
 So  any  method  which  contributes  to  the  formation  of  H2CO3  should  be  OK  as  long  as  it  can  be  regulated  to  prevent  sudden  changes  in  pH.
 Anyway  check  out  this  data  first  :

 I  am  drawing  your  attention  to  a  point  made  in  that  article  which  was  intriguing:  "    Finally,  many  species  of  aquatic  plants  are  able  to  photosynthesize  using  bicarbonate  as  well  as  CO2.  This  is  important,  since  at  pH  values  between  6.4  and  10.4  the  majority  of  DIC  in  freshwater  exists  in  the  form  of  bicarbonate.  "
 
 What  does  this  mean?  Can  we  just  add  bicarb  ?
