 Hello  Experts,
 
   I  have  a  pressurized  CO2  setup  and  regulator  with  solenoid  valve  and  needle  valve  controller.  Yesterday  when  I  was  taking  my  lunch,  I  heard  the  noise  of  something  like  creaming  and  burst.  I  ran  into  my  fish  room  and  found  the  CO2  cylinder  was  making  such  a  noise  like  its  gonna  burst.  Thank  God  to  give  me  at  least  a  little  presence  of  mind,  I  immediately  closed  the  master  valve  of  cylinder.  Mean  time  I  was  looking  at  the  tank,  the  CO2  from  my  external  reactor  was  flowing  like  500  bps  Sad  And  meantime  I  also  closed  the  needle  valve  and  switched  off  the  regulators.  Instead  of  diffused  water  from  reactor  I  saw  air  (CO2)  bubbles  coming  into  the  tank.  Also  found  the  regulator  unit  was  chilled.  
 
 Once  again  thank  God,  nothing  happened  to  fishes  Smile  I  saw  the  cylinder  pressure  gauge  which  is  zero  as  I  closed  the  master  valve.  But  the  other  hand,  the  output  gauge  was  almost  full.  I  let  the  setup  as  it  is  and  checked  in  the  evening,  still  the  output  pressure  gauge  was  metering  to  show  half  of  its  scale.  I  just  wanted  to  see  if  that  has  the  same  problem.  I  opened  the  cylinder  master  valve,  unlucky  me,  the  same  screaming  &  bursting  noise  came  again.  I  then  shutdown  the  CO2  setup  and  called  a  local  technician.  I  expect  him  to  come  tomorrow  (because  a  most  demanding  where  you  have  more  hospitals).  
 
 Just  two  weeks  ago  I  began  dosing  with  the  belief  of  CO2  supply  and  was  set  happy  to  run  my  planted  tank.  Got  hit  Sad  What  would  be  the  reason  and  what  would  have  gone  wrong.  The  noise  was  exactly  like  a  devil  screaming.  Help  me  out  to  understand  what  goes  wrong,  mean  time  I  will  keep  you  posted  with  the  troubleshooting  report.
 
 Thank  God  again  and  again  for  saving  my  fishes  and  me  from  a  disaster!!   Neutral

 i  have  had  this  problem  once  and  i  just  turned  the  dial  on  top  of  the  reactor  to  let  some  of  the  water  flow  in  and  all  was  well.  it  never  happened  again.  
 
 Keep  us  posted...

 Ravi,  Why  don't  you  post  pictures.  There  is  a  lot  of  cheap  Chinese/unsuitable   stuff  -  regulators,  needle  valves,  timers  being  re  branded  and  sold  by  unscrupulous  expert  aquarists.
 There  is  nothing  much  we  can  do.  
 We  are  part  of  society  with  the  good  and  the  evil.

 Thank  you  for  your  kind  comments  :)
 
 @Pradeep,  am  using  Jaqno  CO2  Mixer  as  external  reactor  and  if  I  open  the  top  dial,  the  water  would  spit  out  in  the  room.  So  I  didn't  do  anything,  I  just  waited  to  see  the  response  of  fishes  and  kept  my  air  stones  n  air  pump  handy.  
 
 @Trevor,  I  understand  your  points.  Let  me  wait  for  a  day  and  let  the  technician  look  at  it.  I  had  couple  of  phone  calls  from  friends  from  IAH  to  check  certain  aspects.  I  will  have  them  cleared  with  the  technician.  Once  I  have  complete  report  in  hand  with  good  understanding  of  problem,  I  will  update  you  with  my  learnings.  Hope  this  is  what  I  could  afford  to  the  hobbyist.

 This  is  quite  bad....
 
 Only  recently  did  Vignesh  lose  all  his  fishes  to  a  Co2  regulator  malfunction  isnt  it?

 Is  this  a  new  one  you  bought  in  Chennai  or  the  old  one  that  you  had  problems  with  earlier?  
 
 Happy  to  know  that  the  fishes  are  safe.

 Yes  Vyas,  Vignesh  had  trouble  in  the  past  and  one  another  fellow  hobbyist  too  posted  recently.
 
 Suraj,  this  is  my  old  one.  And  yes,  really  am  happy  that  my  fishes  are  safe  and  your  rainbows  are  still  in  orange/red  color  Smile

 Hi  Ravi,
 
 The  sound  was  probably  from  your  solenoid  going  bust.
 
 Some  solenoids  are  not  built  to  take  fluctuations  in  voltages  &  also  have  different  sine  wave  pattern.
 That  is  the  reason  that  they  chatter  while  connected  to  a  UPS.
 I  lost  2  solenoids  in  a  very  short  period  due  to  our  famous  power  outages  in  Bangalore  quite  a  while  ago.
 
 I  don't  think  this  has  to  do  with  the  regulator,  unless  you  see  frosting  on  the  joints  between  the  gauges  &  the  joints.
 
 All  the  best.
 
 Rgds,
 Prabhu

 Hi  Supra,  thanks  for  the  information  and  your  comments!
 
   Could  you  please  explain  to  me  about  the  frosting  on  the  joints  and  why  this  happens  in  little  brief  way?  Am  just  trying  to  understand  whats  in  there  on  these  sensitive  apparatuses.  I  read  couple  of  articles  today  but  they  were  either  too  much  technical  or  less  informative.

 Simply  put  when  gas  expands,  it  does  so  by  absorbing  ambient  energy  (heat).  So  the  pressurised  gas  escaping  from  any  joint  will  absorb  the  surrounding  heat  to  expand  and  drastically  reduce  the  temperature  around  the  joint  Water  will  condense  and  eventually  freeze  to  form  frost.

 If  I  remember  my  physics  correctly,  gas  drops  in  temperature  as  it  expands.
 When  you  have  gas  coming  out  very  fast  from  a  region  of  high  pressure  to  one  of  low  pressure,  the  gas  absorbs  heat  from  its  surroundings.
 This  drops  your  temperature  around  the  valve  causing  water  vapour   in  that  area  to  condense  and  then  freeze.

 I  think  it  also  means  that  gas  might  be  leaking  from  that  particular  joint.

 Hey  Ravi,
 
 Welcome  to  the  club  of  malfuctioning  regulators.  It's  just  not  you  who  is  suffering  there  are  three  others  in  Chennai  with  the  same  problem  and  two  of  them  have  already  dumped  the  regulator  including  me.  
 
 I  agree  with  Trevors  comments  about  the  cheap  chinese  makes  which  I  recently  happend  to  find  in  Parry  Corner,  near  high  court.  The  price  is  too  cheap  and  I  am  sure  they  will  conk  like  the  way  my  two  regulators  conked.  I  would  have  accepted  it  if  it  was  just  me,  but  now  there  are  4  of  us  with  the  same  problem.  I  guess  its  not  worth  the  risk.  Just  dump  it.
 
 Cheers,
 Prem

 Thanks  for  the  welcome  note  Prem,  how  ever  I  moved  out  of  the  club  just  few  minutes  ago  by  getting  a  new  one.  I  had  the  technician  visiting  my  home  and  he  checked  the  regulator  and  he  did  not  open  it.  But  he  explained  me  the  fact  of  what  would  have  gone  wrong.  Here  it  goes,
 
 1.  If  the  power  fluctuation  is  there,  it  would  trouble  the  solenoid  and  nothing  to  do  with  the  regulator.  If  at  all  the  solenoid  fails,  there  would  not  be  any  supply  of  gas,  but  I  did  see  gas  coming  into  the  tank  after  crossing  the  reactor.
 
 2.  The  problem  could  possible  (99%)  on  the  pin  valve  inside  the  regulator.  If  that  fails,  it  would  create  a  high  pressure  output.  In  this  case  we  could  see  the  gas  trying  to  come  out.  However  we  have  a  needle  valve  which  is  again  controlling.  If  at  all  that  is  not  functioning  well,  you  can  see  all  that  high  pressure  beginning  to  come  out  into  the  reactor/tank.
 
 Experts,  please  correct  my  statements  if  at  all  any  of  these  can  be  declined.  The  new  one  is  double  stage  regulator  with  solenoid  and  needle  valve  which  is  made  in  INDIA  and  used  in  hospitals.  This  person  seem  to  serve  Hospitals  mainly  and  doing  it  as  a  full  time  profession.  Let  me  look  at  my  luck.  Its  too  late  and  will  post  the  picture  of  new  setup  tomorrow  so  that  it  would  be  good  for  you  people  to  comment  more.  Once  again,  thanks  a  lot  for  all  your  support  and  comments   Thumb Up

 happens  to  the  best  of  us  Ravi...and  it  is  very  frustrating  when  even  the  basics  such  as  flow  rate  cannot  be  controlled..i  am  planning  to  throw  away  what  I  have  and  go  for  something  that  has  been  tested  and  is  more  reliable..regulators  are  not  cheap..
