 I  use  a  3  in  1  ista  ceramic  diffuser.  It  is  very  cheap  and  produces  really  fine  bubbles.

 I  use  a  wooden  air-stone  which  gives  out  really  minute  bubbles.

 See   the  posts  on  IAH  regarding  the  risks  involved  in  using  any  form  of  flow  control  on  your  DIY  CO2  setup.

 Not  sure  if  those  bubbles  are  anyway  getting  dissolved.  From  the  pic  it  doesn't  looks  like  that.  Problem  with  DIY  co2  is  that  you  don't  get  good  pressure  to  use  ceramic  diffuser  and  unless  you  do  so  it  doesn't  really  dissolve.  
 
 FYI:  You  can  have  two  bottles  together  to  add  some  more  fun.  I  guess  you  know  how  to  do  that.
 AND  I  don't  see  any  bubble  counter.  Pass  the  co2  through  some  water  to  remove  impurities/foul  smell.  If  you  try  smelling  the  co2  generated  you  will  know  what  am  referring  to   Smile

 @  piercy/  garo....
 am  doing  everything  the  same  except  the  non  return  valve.
 
 i  am  currently  experimenting  with  a  cigarette  filter  instead  of  the  air  stone.
 
 will  let  u  know  the  results...
 
 also  at  our  last  meet  u  were  talking  about  pressurizing  co2....did  u  find  a  way??

 I  think  if  their  are  two  bottles  only  then  their  will  be  enough  pressure  to  get  enough  tiny  bubbles.  But  then  their  should  be  a  drop  checker.

 Thanks  Garothmaan  for  giving  out  the  recipe  in  details,  however  during  my  usage  the  mixing  was  either  too  high  or  too  less   Smile  .  I  even  tried  out  using  ceramic  diffuser  but  the  pressure  build  up  in  the  reactor  kills  the  yeast  very  soon.  The  best  100%  diffusion  is  only  achieved  using  a  bell  type  diffuser  or  connecting  a  powerhead  this  way.  The  bubbles  get  trapped  in  the  upsidedown  bottle  and  the  force  from  the  powerhead  mixes  the  co2  completely.

 Yes  that  idea  of  using  a  primus  stove  tank  for  pressurised  co2   Very Happy  will  be  my  next  experiment.  will  post  here  as  soon  as  I  finish  it.  
 
 Thank  you  Bow   all  ...for  your  inputs.  There  is  no  smell  as  such,  and  I  tasted  the  water,  its  realy  fresh  and  sweet.  
 
 I  will  place  the  pipe  a  little  below  the  soil,  will  that  make  sense?  Smile

 When  you  have  a  power  failure  the  CO2  will  displace  the  water  from  the  power  head  and  it  will  develop  a  "Gas  lock"  when  the  power  comes  back  on?

 Garothmaan,
 
 Thanks  for  your  detailed  explanation,  noted  you  have  used  3  cups  of  sugar  instead  of  2  cups  any  reasons.  I  am  currently  difusing  the  CO2  via  my  internal  filter  and  on  some  instances  the  mix  lasts  for  more  than  2  weeks.

 C02  produced  by  DIY  yeast  method  is  precious,  not  in  terms  of  money,  but  in  terms  of  the  hassle  and  effort  made,  so  it  is  paramount  that  you  utilize  every  single  bit  of  CO2  produced.
 
 1.  For  a  2  ltr  bottle  setup,  3  cups  of  sugar  is  way  too  much!  Sugar  at  high  concentration  is  actually  toxic  to  growing  yeast  cells.
 2.  From  the  pics,  I  can  say  that  you  can  reduce  the  amount  of  yeast  too.  The  aim  is  to  get  a  slow  but  steady  CO2  production.  More  yeast  means  more  rapid  CO2  but  the  mix  gets  exhausted  sooner.
 3.  It  is  paramount  that  you  diffuse  the  CO2  -  either  use  a  reactor  or  a  wooden  airstone,  because  larger  bubbles  means  you  are  actually  wasting  the  CO2.  Cigarette  filter-in-tubing  is  an  innovative  idea,  but  somehow  I  never  succeeded  with  it.
 4.  Attach  a  second  bottle/bubble  counter  -  it  prevents  accidents  in  case  of  back-pressure.  Also  keeps  out  toxic  by-products  formed  during  fermentation  process  from  entering  the  tank.
 
 my  two  cents...

 very  impressive,  thank  you  Bow  
 
 I  have  done  my  2  cup  ratio  and  there  was  no  consistancy,  I  also  did  the  Tea  spoon  yeast  granule  mix  up,  the  reaction  took  too  much  time,  here  the  reaction  is  early  and  consistant  for  atleast  1  week  sometimes  10  days.
 
 Second  bottle?  ok  fine  but  there  will  be  all  the  extra  effort  to  stop  leakages  ,  but  i'll  try  again  with  mseal  this  time.  
 
 Do  I  have  to  put  water  in  the  second  bottle?  and  then  transport  the  co2  back  to  tank?

 garothmaan  May  be  this  will  help,  my  Jugaad  DIY  CO2
 The  small  bottle  contains  water  to  which  the  outlet  pipes  from  both  tank  joined  by  a  T  joint  is  dipped  ,  this  will  also  act  as  a  bubble  counter  for  me,  the  outlet  pipe  from  this  small  bottle  goes  into  a  airstone  which  is  placed  below  a  small  internal  filter  which  will  diffuse  the  co2  into  the  water  nicely

 Hello,  
 
 You  set  up  looks  good  basic  CO2  generator,  try  to  use  some  alternative  for  the  air  stone  as  it  will  disintegrate  soon  due  to  reaction  with  CO2  gas.  in  case  you  want  more  CO2  gas  for  you  tank  then  you  can  also  use  a  mix  of  Vinegar  &  Baking  soda  however  the  problem  in  this  option  is  that  lot  of  gas  will  be  generated  and  in  case  you  use  a  mettle  bottle  with  regulator  it  will  be  good.
