 Would  have  loved  to  write  on  setting  up  a  pressurized  Co2  delivery  system  on  a  students  budget  (no  cylinder  included)  but  I  would  have  been  stepping  on  too  many  commercial  guys  toes.   
 
 Trevor,  I  am  a  student  of  yours.My  humble  reuest  Could  you  please  throw  some  light  on  this  setup                

 
 Ok,  This  will  take  sixty  seconds  to  assemble  this  set  up.  But  at  least  half  an  hour  for  me  to  photo  graph  and  post.
 Its  all  push  and  lock.
 First  buy.

 Next  the  connector.  The  brass  connector  is  screwed  on  to  the  Co2  regulator.

 Cut  the  P.U  hose  to  the  required  length  and  push  and  lock  it  into  the  needle  valve.
 Please  note.
 The  polyurethane  (P.U)  hose  will  have  a  wall  thickness  of  one  mm.  
 An  inner  diameter  of  4  mm  and  and  an  outer  diameter  of  6mm.  
 Used  for  pneumatic  operations.

 The  other  end  you  push  into  a  diffuser/reactor  or  even  the  air  inlet  of  a  power  head/filter.
 
 Release  a  bubble  a  second  or  more  from  the  needle  valve.
 
 The  price  can  be  further  reduced  by  using  a  brass  wheel  type  Indian  needle  valve.
 
 A  silicon  tube  can  be  use  at  the  end  to  push  into  the  air  inlet  since  the  P.U  hose  is  quite  stiff.
 Game  up.  Time  for  coffee.  Yes,  Its  a  student  budget.
 
 What  else  do  you  need  ???

 Great  one,  Trevor!
 
 Very  nice,  and  illustrations  were  very  good  too.
 
 Can  we  have  approx  prices  of  the  components,  just  a  rough  guideline  value  would  be  really  helpful.
 
 Thanks  a  ton,  Trevor.  That  was  some  awesome  info!   Rock On

 Nice  write  up  Trevor  ....  as  usual   Smile  
 
 In  case  anyone  is  thinking  of  how  to  get  to  know  the  exact  bubble  per  second  to  tune  the  needle  valve  to  ....  then  here  goes.
 
 You  need  a  500  Ml  coke  pet  bottle,  drill  2  holes  in  the  cap,  just  enough  to  push  in  a  connector  used  for  joining  air  tubing  available  at  any  LFS.  The  holes  should  be  made  in  such  a  way  that  the  connector  fits  in  tightly.
 
 Now  one  is  the  inlet,  this  is  the  tubing  from  the  needle  valve,  inside  the  bottle  have  a  regular  air  tubing  that  runs  almost  till  the  bottom  of  the  bottle  connected  to  the  connetor.
 
 fill  the  bottle  half  way  with  water.
 
 The  other  is  the  outlet,  from  here  connect  the  tubing  to  the  Reactor/Diffuser.
 
 fine  tune  the  Needle  Valve  till  you  see  one  bubble  per  second  coming  out  from  the  tube.
 
 Your  bubble  counter  is  Done   Smile  
 
 PS:  Sorry  about  the  lousy  picture     Sad

 Not  Necessary  Seetaram.  Simple.
   
 Hold  the  delivery  tube  under  water  before  fixing  to  your  dispersal  unit.  
 That  is  your  reactor/diffuser/air  inlet  of  power  filter/power  head  in  the  aquarium..
 
 and  then  adjust  the  needle  valve  to  a  bubble  per  second  etc.
 
 Even  after  fixing  to  the  power  filter  put  the  filter  off  in  the  aquarium.  At  an  angle  the  Co2  bubble  will  come  straight  up.  Fine  tune  your  needle  valve  now.  Some  skill  may  be  needed.  Smile

 Okay,  You  will  have  to  work  out  this.
 The  main  cost  will  be  be  the  Co2  regulator.  That  is  3/4  of  one.  The  rest  are  very  economical.  They  will  total  the  remaining  quarter.
 Avoid  the  fiber  needle  valve  for  real  economy.
 The  brass  needle  valve  is  sturdy,  economical   and  lasts  many  years.  Fine  tuning  is  a  little  difficult  on  it.  But  once  it  is  set  there  is  no  need  to  fiddle  with  it.
 Pic  shows  the  push  and  lock  fitting  on  both  ends  -  the  in  and  out  of  the  Indian  brass  needle  valve.

 Trevor  Sir,
 
 Really  useful  post.  Truly,  each  picture  is  equal  to  1000  words.
 
 But  can  you  split  this  post  and  start  it  under  the  heading  Co2  delivery  system  in  students  budget  or  something  like  that?  It  will  be  very  helpful.
 
 Regards,
 Nayak.

 @Trevor  Sir.....  Many  many  thanks  for  the  post.  It's  really  helpfull.  Today  only  I  received  my  CO2  accesorries.   Cheering  
 
 I  have  a  small  question  here.  I  was  planning  to  use  White  Silicon  Tubing  for  the  connection  instead  of  P.U  hose.  Will  it  be  advisable  and  safe  to  use  only  sillicon  tubing  throughout  the  system?

 Now  this  weekend  I  will  have  to  go  out  hunting  for  these  items  and  see  what  all  I  can  find.
 Thanks  for  the  help.
