 My  planted  tank  is  a  4footer.  I  currently  have  the  bubble  counter  connected  to  a  reactor  (with  4  bio  balls)  which  in  turn  is  connected  to  a  powerhead.
 
 I  want  to  change  this  to  something  more  aesthetic  and  less  cumbersome.
 
 will  a  glass  diffuser  be  sufficeint?  I  will  connect  the  co2  outlet  frm  the  bubbkle  counter  into  the  glass  diffuser  and  i  will  throw  out  the  reactor  and  the  powerhead.
 
 let  me  know  your  experience  on  this....

 I  remember  Madan  posting  something  about  an  ADA  beetle  diffuser  in  a  large  tank.
 Seetharam  is  another  person  who  uses  diffusers  only,  but  his  tank  is  only  50  Gals

 Pradeep,
 
 You  can  also  go  in  for  a  Glass  CO2  reactor  that  Rufus  makes.  It  is  what  was  being  used  by  all  of  us  before  the  advent  of  diffusers.  Give  him  a  buzz  on  9845039631  and  he  will  be  able  to  source  it  for  you.

 Use  2  for  a  large  tank  at  either  end

 Hi  PC  -  I  go  with  only  glass  diffusers  due  to  aesthetic  appeal,  for  tanks  as  large  as  4  footers,  you  could  look  at  the  beetle  style  diffusers  as  Unni  mentioned  with  large  ceramic  base  ,  refer  to  link  below.
 
 http://adana.co.jp/_e_product/24_index.html
 
 If  you  are  planning  to  use  smaller  diffusers,  it  would  be  good  to  go  for  2  at  either  end  of  your  tanks  as  Preetam  has  mentioned.
 
 If  you  have  a  canister  with  good  capacity  running  on  your  tank  ,  you  need  not  worry  about  CO2  getting  localized  when  you  use  diffusers.

 Instead  of  a  single  Glass  diffuser,  It  will  be  better  to  go  for  Multi  point  injection  with  smaller  diffusers.  
 
 But  personally,  for  a  4  feeter  or  More,  I  would  go  for  an  External  Reactor  driven  by  a  powerful  pump.

 You  will  need  a  2-way  /3-way  Co2  splitter  depending  on  the  number  of  diffusers  you  plan  to  use.  This  is  needed  to  regulate  flow  through  each  diffuser  individually.

 The  problem  with  Multi-Point  Injection  is  you  will  need  individual  Needle  Valves  for  each  which  could  take  your  overall  cost  up.  
 
 A  good  option  would  be  the  external  reactor  as  Tirtha  said,  but  go  for  a  good  one  or  you  will  face  problem  with  leakages

 Split   the  CO2  like  this.  You  will  need  individual  needle  valves  for  each  outlet.  you  will  get  these  pneumatic  splitters  in  all  shapes  and  with  upto  4  outputs.

 Exactly....  You  just  have  to  split  the  CO2  output  and  install  Needle  Valves  for  both  the  split.  This  way  you  will  have  a  full  control  on  your  CO2  supply.  As  you  have  a  4  feeter,  I  think,  a  injection  points  will  be  more  than  enough.
 
 @Preetam....  How  are  those  needle  valves  working?  I  had  them  before,  but  it's  a  PIA  to  fine  tune  them  as  well  as  to  keep  the  bubble  count  steady.  I  throw  them  away  and  moved  into  brass  needle  valves  later.

 It  takes  me  a  few  hours  to  set  them,  I  leave  them  alone  till  I  need  to  get  the  cylinder  refilled.  I  may  have  to  do  this  2-3  times  a  year.  These  are  not  yet  a  PITA  so  i  let  them  be  Chuckle  
 
 Can  you  post  a  picture  of  a  brass  needle  valve?  I  might  be  getting  my  self  an  other  tank,  so  i  can  explore  the  option  of  using  one  of  those....

 thanks!!  The  ADA  diffusers  look  great  but  are  very  expensive  :-(
 
 Splitting  the  lines  are  difficult  due  to  budget  issues.  Can  i  get  a  large  diffuser  that  will  suffice  for  my  4feet  tank?

 I  use  a  simple  BOYU  Glass  diffuser  and  above  it  I  place  a  small  power  head  and  it  does  the  job  well  for  my  tank.The  fine  bubbles  from  the  diffuser  are  again  further  crushed  and  mixed  by  the  powerhead.
