 trust  me  an  artical  of  this  kind  can  save  a  lot  of  money  and  time  for  newbies  like  us.
 thanku  again

 The  result  of  addition  of  Co2  and  proper  lighting  to  an  established  planted  tank.  Limnophila  sessiliflora/Dwarf  Ambulia  goes  boom  in  a  few  hours  at  the  top  as  you  can  see  in  the  attached  picture.
 Its  a  good  idea  to  grow  these  stem  plants  in  pots.  When  cutting  to  reduce  height  always  cut  from  the  bottom  and  replant  the  top  for  better  visual  appeal.

hi
 
      Thanks  trevor,  raghu  and  suuresh  for  the  info.  Unfortunately  have  done  the  set  up  in  the  same  way  but  not  able  to  control  the  bubble  count  to  desired  levels  in  both  tanks.  I  am  guessing  that  tanks  being  at  diffrent  levels  dose  not  matter,  is  this  true??  Also  wanted  to  add  that  the  co2  cylinder  is  placed  higher  than  the  smaller  tank.  Will  be  looking  forward  to  your  suggestions.
 
    Thanks
    Regards
       HArshal.                

 
 This  lush  cement  tank  of  V.Raghu  is  on  the  terrace.  
 He  uses  the  same  Co2  cylinder  which  is  on  the  ground  floor  to  put  Co2  into  his  second  floor  terrace  cement  tank.  
 That  should  be  at  least  twenty  feet  high.  
 He  has  a  bubble  counter,  reactor  and  pump  and  uses  natural  sunlight  which  is  controlled  by  a  double  fold  of  the  green  mat  seen  in  the  top  corner.
 Remember  the  reach  of  Co2  does  not  depend  on  the  size  of  your  cylinder  or  the  level  of  your  tanks.  
 It  depends  on  the  pressure  in  your  piping.  
 The  Co2  cylinder  should  be  kept  at  a  lower  level.

    Thanks!  thats  what  i  wanted  to  know.  This  is  the  reason  why  I  am  not  able  to  get  any  co2in  my  2nd  tank.  The  cylinder  is  at  a  higher  level  than  the  tank!

I  need  help  with  a  problem  I  have  faced  and  not  resolved  for  a  while  now.  I  want  to  use  1  cylinder  to  power  2  tanks,  I  tried  doing  this  with  a  "T"  and  seperate  needle  valves  for  both  the  cylinders  but  was  not  sucessful  in  maintaining  the  bubble  rate  to  what  I  desired  in  both  the  tanks.                

 
 Hello  Harshal  ,
 
 Posting  now,  as  I  was  away  for  sometime.
 IMPO
 1. Cylinder  level  is  not  a  crucial  factor  &  will  not  affect  the  output  pressure.
 2. The  diagram  shown  is  an  exploded  view  of  a  dry  CO2  Cylinder  &  not  a  Liquid  CO2  Cylinder.  The  same  may  hold  true  for  other  application  as  in  fire  fighting.
 3. Liquid  CO2  cylinders  do  not  have  the  tubing  inside;  as  it  would  be  forced  out  with  high  pressure  damaging  the  regulator  &  causing  dangerous  situations.
 
 The  issue  I  see  with  your  setup  is:  you  are  diffusing  CO2  from  two  equipments  using  diverse  principles;  one  working  on  back  pressure  (diffuser)  while  the  other  has  no  pressure  build  up  (reactor).  
 
 You  can  try  increasing  the  operating  pressure  at  the  regulator  to  about  4bar  and  individually  adjust  the  bubble  count  for  the  diffuser  &  the  reactor.  Note:  since  the  working  principles  are  different  you’ll  individually  need  to  adjust  the  flow.  The  flow  rate  (FR)  on  the  diffuser  will  always  be  higher  as  compared  to  that  of  the  reactor.  Unless  the  FR  is  higher  on  the  diffuser  the  pressure  will  not  build  up  &  CO2  will  always  find  an  escape  route  to  the  reactor.  Do  set  the  FR  on  the  reactor  first  &  then  on  the  diffuser.
 
 I’m  sure  that  if  you  use  a  reactor  on  both  the  Aquariums,  you  will  not  face  this  issue.  Moreover,  with  diffusers,  they  tend  to  get  choked  up  over  a  period  of  time  &  require  frequent  fiddling  of  flow  rate.
 
 Hope  this  helps.

 1.  Cylinder  level  is  not  a  crucial  factor  &  will  not  affect  the  output  pressure.
 
 True.  Level  will  not  affect  the  output  pressure.
 Why  the  Co2  cylinder  should  be  kept  at  a  lower  level.
 There  is  a  phenomenon  known  as  dumping.   This  is  when  the  cylinder  gas  is  nearly  exhausted.  At  this  time  the  regulator  becomes  unstable  and  there  is  uncontrolled  surges  of  gas  into  the  planted  tank.  This  creates  an  excessive  amount  of  Co2  in  your  aquarium.  If  not  checked  in  time  you  could  lose  all  your  fishes.  A  lot  of  guys  including  our  gurus  have  lost  a  lot  of  fish  and  sometimes  the  entire  aquarium  livestock.  
 This  dumping  happens  when  90%  of  the  gas  in  the  cylinder  is  exhausted.  You  have  to  be  wary  when  the  cylinder  pressure  drops  below  the  60  psi  mark.  It’s  best  now  to  disconnect  and  give  your  cylinder  for  refilling.  Using  a  two  stage  regulator,  using  smaller  cylinders  and  keeping  the  cylinder  at  a  lower  level  will  help  avoid  or  at  least  reduce  the  damage  in  the  event  of  it  occurring.
   
 2.  The  diagram  shown  is  an  exploded  view  of  a  dry  CO2  Cylinder  &  not  a  Liquid  CO2  Cylinder.  The  same  may  hold  true  for  other  application  as  in  fire  fighting.
 
 True.  The  diagram  is  of  a  Co2  fire  extinguisher.  It  is  only  to  show  the  location  of  the  master  shut  off  valve.  The  master  shut  off  valve  is  vital  and  has  to  be  shut  off  in  any  emergency.
 Some  refillers  claim  that  the  wheel  valve  gets  damaged  while  transporting.  That  is  why  the  wheel  valve  is  removed  and  an  Allen  key  is  used.  If  you  use  an  allen  key  make  sure  the  key  is  hung  around  the  neck  of  the  cylinder.
 
 3.  Liquid  CO2  cylinders  do  not  have  the  tubing  inside;  as  it  would  be  forced  out  with  high  pressure  damaging  the  regulator  &  causing  dangerous  situations.
 
 True.

 Hi  Deepak!!
 
      happy  new  year!!  and  thanks  I  think  you  have  done  it  my  friend  this  does  finally  make  sense  Just  saw  the  post  hence  a  late  reply.  Well  now  ofcourse  have  to  fig  out  how  to  inject  co2  in  both  tanks  and  what  to  use,  A  co2  reactor  might  be  too  much  for  the  small  tank........  Confused   Well  lets  see.
 
   Hi  trevor  
    Happy  new  year!!  Guess  I  misunderstood  what  you  were  tring  to  tell  me.  For  some  reason  I  was  convinced  that  the  co2  cylinder  at  a  higher  level  was  the  reason  why  the  set  up  was  not  working  ,  guess  i  was  wrong.
 
    Regards
       Harshal.

 Thank  you  &  wishing  you  the  same.
 
 If  space  in  the  Aquarium  is  a  concern,  then  I  would  recommend  an  external  DIY  CO2  Reactor,  make  a  small  one!
 
 I've  never  used  this  setup  (Diffuser  &  reactor  on  the  same  regulator)  so  won't  be  able  to  provide  a  workaround  or  comment  at  this  moment.
 
 See  you  sometime  soon!

 One  word  of  caution  when  you  buy  a  Fire  Extinguisher  Cylinder  to  use  in  a  planted  tank.
 
 Make  sure  that  the  internal  pipe  connecting  the  master  valve  to  the  bottom  of  the  cylinder  is  removed.  Otherwise  Liquid  CO2  will  enter  your  regulator  with  disasterous  consequences.
   
 For  Fire  extinguishing  purposes  Liquid  CO2  is  directly  ejected  to  the  surroundings  so  that  it  suddenly  expands  to  atmospheric  pressure  and  cools  the  surroundings  in  addition  to  smothering  the  fire.  A  Fire  Extinguisher  is  used  in  the  upright  position  hence  the  internal  tube.
 
 As  you  can  see  from  the  refilling  pictures  in  this  thread,  the  main  cylinder  is  laid  upside  down  so  that  Liquid  CO2  is  filled  into  your  smaller  cylinder.  Both  should  not  have  an  internal  pipe.
 
 This  is  the  main  and  important  difference  between  a  CO2  Cylinder  used  for  Fire  Extinguishing  purposes  and  that  used  for  medical,  welding,  beverage  purposes.
 
 Take  Care.
