 I  use  a  2  ltr  pet  bottle  to  make  CO2  for  my  tank.  But  some  how  since  last  time  I  am  not  able  to  get  any  CO2  production  at  all.  I  have  tried  many  times  and  all  is  going  waste  without  any  CO2  production  at  all.  I  use  this  mixture  by  adding  2  cups  of  sugar  in  3/4  bottle  water  and  1/2  tsp  dry  yeast  and  a  pinch  of  baking  powder.  Once  somewhere  I  read  about  adding  baking  soda,  after  adding  it  made  the  liquid  like  gelly...wonder  if  it  useful.
 
 I  wonder  if  its  the  low  temperature(15  degrees  celcius)  that  is  inhibiting  the  production  of  CO2  .I  have  also  kept  the  the  whole  solution  in  bright  sun  and  a  heater  but  still  no  effect.
 
 Please  do  reply  soon.
 
 Thanks

 Since  you  mention  "some  how  since  last  time  I  am  not  able  to  get  any  CO2  production"  do  you  mean  you  were  able  to  get  CO2  with  your  earlier  preparations  in  the  same  setup?
 
 Your  mix  seems  OK.
 @  2cups  of  Sugar(Around  200-300gms)  in  1.5  litres  water,  along  with  1.5tsp  dry  yeast  and  a  pinch  of  baking  powder.
 But  baking  powder  should  not  turn  your  water  jelly.  Cut  down  on  it  by  around  80%.
 
 As  you  mention  temp  15degrees  will  definitely  play  a  major  role  in  reducing  the  output.  Placing  the  solution  in  sunlight  helps,  since  I  use  the  same  method  in  Bangalore.  But  the  extent  of  sunlight  is  only  in  the  morning  for  around  1  hour.  I  am  worried  about  your  heater.  What  temp  is  it  at  and  could  it  have  killed  all  the  yeast?
 
 Also  please  check  the  setup  for  any  leaks  using  soap  water,  which  could  be  one  of  the  reason.
 
 Regards,
 Nayak.

 Yes  I  was  getting  good  results  about  1  month  back  and  plus  I  could  see  small  bubbles  rising  to  the  surface.  Now  its  just  cloudy  water.  I  meant  adding  baking  soda  not  baking  powder  which  had  turned  my  solution  to  gelly.
 
 I  kept  the  solution  near  a  room  heater  not  near  the  aquarium  heater  for  an  hour  or  plus  nothing  happened.  Aquarium  temperature  is  around  24-26  degrees  celcius.  15  degrees  celcius  is  the  temperature  in  my  house  not  the  aquarium.
 
 Anyways  thank  you  very  much  rasikanayak.

 Baking  soda  is  pure  "sodium  bicarbonate"  and  baking  powder  is  "sodium  bicarbonate  along  with  acidifying  agent  and  a  drying  agent".  I  have  used  both  and  experienced  not  much  difference  between  the  two.
 
 Anyways,  Thank  you.

 Activate  the  yeast  in  a  covered  cup  full  of  warm  water  +  3-4  teaspoons  of  sugar  first.  Add  1/2  to  1  teaspoon  of  yeast  to  the  sugar  water  then  cover  it  and  keep  it  somewhere  warm  (not  too  hot  !!)  When  you  see  froth  at  the  top,  you  can  add  it  to  the  main  2  ltr  bottle  that  has  water  +  sugar.  Getting  a  steady  amount  of  CO2  can  take  upto  a  day  or  two  so  be  patient  and  keep  the  bottle  closed.  CO2  is  only  produced  when  the  yeast  is  under  anaerobic  conditions.

 Mortis  will  follow  your  suggestions  and  will  update  on  the  result  in  about  a  day..

 you  wont  be  able  to  get  CO2  production  with  15  degrees.  you  need  higher  temp.  place  a  table  lamp  with  an  old  fashioned  bulb  facing  the  bottle.  low  temperature  is  not  good  for  the  production.

 Hi,
 
 This  is  how  I  made  my  DIY  co2  system,  very  simple.  All  the  information  is  available  on  the  internet,  google,  youtube  and  so  on.  Search  for  DIY  co2  system.
 
 Anyways  my  co2  is  working  for  months  now,  my  expediture  is  42  rs  bluebird  brown  sugar,  which  last  for  30  days.  (changes  twice)  Yeast  last  for  3  or  4  months  since  I  use  half  a  teaspoon.
 
 I  use  two  bottles,  the  second  bottle  is  for  fitering  the  co2  otherwise  in  few  days  your  tank  is  going  to  smell  with  alcohol.
 
 I  would  not  be  able  to  explain  the  entire  setup.  I  would  upload  images  of  my  co2  setup  with  full  explaination  in  future  to  a  free  hosting  site.
 
 Note:  -  In  the  bottle  first  add  brown  sugar  then  fill  it  up  with  luke  warm  water  and  then  add  yeast  half  a  teaspoon.
