 Ready  for  another  cause  initial  was  delivering  very  slowely.  So  what  i  have  to  do  is:
 1)  take  a  cup  of  luke  warm  water  and  add  the  half  teaspoon  of  yeast  with  pinch  of  baking  soda  and  cup  of  sugar.
 2)  simultaneously  1lit  bottle  fill  it  upto  3/4.
 3)  add  the  yeast  mixture  into  the  bottle  after  activating  it.  Shake  the  bottle  &  tight  the  cap  for  few  hour.
 4)  use  it  when  bottle  is  tighten....
 Is  this  recipee  is  correct  or  not  ????  Suggest  me  if  have  mistaken.

 No  it  is  a  little  erroneous.  Simply  drop  200  gms  of  sugar  in  a  2ltr  bottle,  add  1  table  spoon  of  yeast  in  it  (  bakers  yeast  is  best),  1  half  teasponn  of  baking  powder.  Fill  3/4  water.  Waiit  till  next  day.  the  bottle  will  be  tight  hard-  release  the  CO2  very  slowly  in  very  thin  mist  form,  it  will  dissolve  half  way  in  the  tank.  Thumb Up

 @Kapil  -  If  I  were  you,  I  wouldn't  leave  the  bottle  tight-capped  with  the  mixture.  Should  you  forget  to  check  it  in  time,  there  are  chances  the  bottle  may  pop  due  to  pressure  and  you'll  have  a  smelly  mess   Chuckle  Experts  may  please  correct  me  if  I  am  wrong  here.  
 
 I  keep  mine  into  a  spare  bubble  counter  (output  of  which  is  open)  overnight  and  usually  start  seeing  bubbles  in  the  morning.  I  give  it  some  more  time  so  the  bubble  rate  is  relatively  steady  and  then  connect  it  to  the  tank's  bubble  counter.

 No  the  bottle  wont  pop,  unless  you  have  filled  it  up  to  the  neck.  its  5  years  now,  I  have  never  seen  the  CO2  recepticle  pop.

 Thanks  garothmaan
 Few  queries:
 1)   What  kind  water  pour  into  bottle?  Means  luke  warm  or  normal?
 2)  can't  make  the  sense  of  your  statement  "release  the  CO2  very  slowly  in  very  thin  mist  form,  it  will  dissolve  half  way  in  the  tank."  so  please  explain
 3)  could  i  make  this  mixture  in  1l  bottle?  Because  i  am  already  running  1l  bottle  with  slower  flow  rate.  what  is  the  benefit  of  2l  water??
 
 By  the  way  i  found  the  reason  behind  slower  flow  rate  is  that  i  haven't  used  any  kind  of  check  valve.  When  the  output  end  of  CO2  is  just  beneath  the  water  surface  flow  rate  is  awesome(approx.  1bps)  but  when  as  end  goes  deeper  in  water  the  water  in  tank  enters  in  co2  tube  for  specific  time  and  goes  out  when  co2  pressure  is  enough  to  push  it  back,  i  think  absence  check  valve  (non  return  valve)  is  the  reason  behind  slowet  flow  rate

 Use  normal  water  no  need  to  use  warm  water.  Luke  warm  water  is  used  during  winters  but  in  any  case  the  reaction  starts  next  day.

 Firstly  the  concept  of  BPS  has  no  meaning,  as  in  the  night  the  proportions  of  CO2  cant  be  meassured.  Then  again  the  consumption  of  CO2  by  plants  cant  be  meassured  unless  you  know  how  many  plants  take  how  much  CO2.  So  BPS  is  therefore  havng  no  logic  IMO.
 
 I  have  seen  BPS  -  bubble  go  straight  upto  the  surface  and  the  gas  simply  escapes,  what  Sense  does  that  make?,  So  I  decided  a  better  way  of  dissolving  the  CO2  and  that  is  not  let  the  gas  go  up  and  escape,  therefore  a  very  thing  line  of  bubbles  which  is  like  a  "smoky  relaease"  is  more  appropriate  then  BPS.

 How  much  oxygen  is  required  for  200  gms  of  Sugar?  which  gas  is  heavier  Carbon  or  Oxygen?  anyways  even  I  dont  know  Chuckle  ....to  keep  more  water,  we  need  more  volume  to  hold  water,  so  use  2ltr  bottle.  
 
 Same  way  in  2  ltrs  bottle  3/4  will  leave  how  many  pounds  of  gas  collection  area?  and  in  1ltr  bottle  3/4  will  leave  how  much  gas  collection  area?

 How  can  it  be  awesome?  did  you  meassure  the  CO2  in  the  water  whether  it  has  dissolved  or  not?
 
 The  CO2  release  must  be  at  the  bottom  so  that  when  bubbles  rise  they  should  become  smaller  in  size  and  then  a  very  small  bubble  should  rise  to  the  surface  to  release  the  gas.  therefore  we  can  understand  by  this  action  that  atleast  a  small  part  of  CO2  is  getting  mixed  in  water.  If  the  bubble  size  is  same  through-out  the  rise  to  the  surface  then  there  is  no  dissolution.
 
 
 All  this  is  experimented  and  meassure  and  then  give  to  you  my  dear  Very Happy

 @Kapil  -  Are  you  simply  placing  the  air-line  tube  in  the  tank?  Or  are  you  using  an  air-stone?  As  garothmaan  sir  pointed  out  above,  the  co2  is  hardly  dissolving  if  the  bubbles  reach  up  straight  to  the  surface  and  then  pop.
 
 You  can  try  the  following  for  better  diffusion:
 1.  Add  a  small  internal  filter  and  connect  the  co2  to  its  input  (some  have  a  small  air-pipe  connected,  you  can  use  this).  If  you  use  a  timer  for  your  lights,  you  can  run  this  filter  on  the  same  timer,  so  co2  and  lights  come  on  together.
 
 2.  Use  an  unused  ear-bud  (yes,  a  ear-bud,  I've  tried  it)  or  half  an  end  of  it  to  jam  the  end  of  the  co2  pipe  (the  cotton  part  should  face  out)  and  place  it  as  deep  as  possible  in  the  tank.  Once  there's  enough  gas  pressure  to  counteract  the  pressure  of  water,  you'll  see  very  tiny  bubbles  like  mist  from  the  cotton  bud  and  going  straight  up  and  dissolving  on  the  way  to  the  surface.  This  method  is  simple  and  very  effective  but  needs  good  water  circulation  for  better  distribution  of  the  Co2.
 
 And  dont  worry  about  the  check  valve.  You  wont  need  it  as  long  as  your  co2  bottles  are  on  the  same  level  or  above  your  tank  level  and  you're  using  a  bubble  counter  bottle.  The  bubble  counter  will  make  sure  the  yeast  solution  doesn't  enter  your  tank.
 
 Hope  this  helped.

 By  the  way  i  found  the  reason  behind  slower  flow  rate  is  that  i  haven't  used  any  kind  of  check  valve.  When  the  output  end  of  CO2  is  just  beneath  the  water  surface  flow  rate  is  awesome(approx.  1bps)  but  when  as  end  goes  deeper  in  water  the  water  in  tank  enters  in  co2  tube  for  specific  time  and  goes  out  when  co2  pressure  is  enough  to  push  it  back,  i  think  absence  check  valve  (non  return  valve)  is  the  reason  behind  slowet  flow  rate                

 
 How  can  it  be  awesome?  did  you  meassure  the  CO2  in  the  water  whether  it  has  dissolved  or  not?
 
 The  CO2  release  must  be  at  the  bottom  so  that  when  bubbles  rise  they  should  become  smaller  in  size  and  then  a  very  small  bubble  should  rise  to  the  surface  to  release  the  gas.  therefore  we  can  understand  by  this  action  that  atleast  a  small  part  of  CO2  is  getting  mixed  in  water.  If  the  bubble  size  is  same  through-out  the  rise  to  the  surface  then  there  is  no  dissolution.
 
 
 All  this  is  experimented  and  measure  and  then  give  to  you  my  dear  Very Happy                

 
 Thanks  for  valuable  support.  BTW  i  do  not  have  any  kind  of  measuring  instrument  for  co2.  Further  when  bubble  of  co2  escapes  from  tubing  they  are  not  smoky  also  size  of  same  remains  constant  until  it  blasts  at  surface  Shocked  .  
 I  watched  your  video.  Your  co2  is  awesome  with  excellent  speed  Thumb Up   How  you  have  accomplished  this  ???  I  have  started  the  procedure  :

No  it  is  a  little  erroneous.  Simply  drop  200  gms  of  sugar  in  a  2ltr  bottle,  add  1  table  spoon  of  yeast  in  it  (  bakers  yeast  is  best),  1  half  teasponn  of  baking  powder.  Fill  3/4  water.  Waiit  till  next  day.  the  bottle  will  be  tight  hard-  release  the  CO2  very  slowly  in  very  thin  mist  form,  it  will  dissolve  half  way  in  the  tank.  Thumb Up                

 
 Let's  hope  for  the  best.  Please  keep  in  touch.
