 I  see  no  reason  why  it  should  not  work.Just  check  whether  the  airline  tube  is  fixed  properly  to  the  bottle.Examine  whether  there  is  a  leak  or  not.

 I  think  you  need  to  alter  the  amount  of  yeast  you  are  using.Thing  is  more  yest  -  more  co2  generation  -  but  less  life,  less  yeast  -  average  co2  generation  -  more  life.
 
 Try  and  experiment  with  the  yeast  amount  keeping  other  things  constant,  you  will  soon  know  exactly  how  much  you  need.

 There  are  other  things  that  you  might  want  to  consider:
 
 1.  ambient  temperature  -  cooler  it  is,  lesser  co2  generation.  (I  stay  in  delhi,  in  peak  summers  i  had  better  co2  generation)
 2.  DIY  co2  generation  is  erratic.  Ive  personally  experienced  this-for  maybe  a  day  or  2  there  would  be  very  less  or  practically  no  co2  generation  and  then  suddenly  it  starts  bubbling.
 3.  add  the  yeast  to  1/2  cup  warm  water,  let  it  dissolve,  after  about  20  mins  add  to  already  dissolved  warm  sugar  solution.
 4.  Sugar  should  be  between  1/2  -  3/4  cup  maximum  (any  normal  tea  cup  &  not  a  coffee  mug).
 5.  Make  sure  the  yeast  is  activated.
 6.  make  sure  all  tubing,  joints,  etc  are  airtight.  I  have  noticed  sometimes  my  bottle  caps  get  slightly  lose  over  time,  causing  a  fizzing  sound  near  the  neck  of  bottle.  Turn  the  bottle  not  the  cap  when  you  are  sealing  it  shut.

 Too  much  yeast,  too  less  water.  Yeast  ate  sugar,  turned  water  acidic  and  in  process  died  themselves.  
 
 First  fill  two  cups  of  boiling  water  in  2  lts  bottle  .  Add  two  cups  of  sugar  in   it.  Dissolve  by  shaking  bottle  thoroughly.  This  also  disinfects  bottle  upto  a  certain  level.  Add  cold  water  upto  the  start  of  neck  of  bottle  (  till  the  point  from  where  bottle  starts  tapering.  Add  one  table  spoon  full  of  yeast.  This  mixture  will  start  producing  co2  in  less  then  12  hrs  and  will  last  atleast  for  2  weeks  or  more.I  know  because  i  m  using  it  for  my  planted  250  ltrs  tank  and  plants  are  doing  absolutely  fine.  Though  no  success  with  Glosso..
