 An  idea  borrowed  from  people  who  like  to  overclock  their  processors...  I  give  you:
 
 
 THE  BONG  COOLER!!!
 
 
 This  link  is  a  comparison  between  the  bong  cooler  and  commercial  CPU  cooling  units.  
 
 Note  the  evaporative  cooler  with  fan  ultimately  dropped  the  temperatures  to  under  20C...  this  was  for  a  small  volume  of  water  heated  to  about  50C.  I'd  expect  a  similar  cooler  to  drop  tank  temperatures  by  about  10C.  not  really  useful  for  marine  setups,  unless  you're  up  to  cleaning  off  salt  deposits  and  topping  off  the  tank  daily.  An  ideal  setup  for  planted  freshwater  aquaria  or  for  freshwater  fish  that  need  cool  temperatures.

 .....and  I  thought  this  was  a  cooler  that  bengalis  particularly  favoured!  Confused

 Rahul,
 
 This  is  very  good  for  cooling,  but  don't  you  think  that  CO2  loss  will  be  very  high  with  this  process  ?

 It  looks  like  our  old  fashioned  "hookah".  I  still  have  old  ones  at  my  grandfather's  house.
 Have  they  been  used  for  aquariums.  It  looks  like  a  simple  inexpensive  device.
 How  much  is  it  more  efficient  then  small  fans  blowing  air  across  the  surface  of  water.

 From  what  i  could  gather  from  the  site..water  cools  faster  if  the  surface  area  of  water  that  is  in  contact  with  the  air  is  more.  When  you  just  blow  air  over  the  surface  the  surface  area  is  comparetilvely  less  than  the  same  volume  of  water  being  sprinkled  in  the  form  of  tiny  droplets.  This  can  be  explained  in  the  same  way  that  a  water  in  a  shallow  plate  cools  faster  than  in  a  glass.    Very Happy

 Will  there  be  more  cooling  if  the  chamber  is  longer  for  the  same  amount  of  air  entering?
 How  much  will  it  cool  the  water  at  30  c  if  the  air  temp  is  30  c  ?
 
 Thanks  and  regards
 Rahul

 You  can  increase  cooling  efficiency  by  increasing  the  height  of  the  tower  and/or  increasing  the  diameter  and  adding  additional  fans.
 
 You  will  have  to  experiment  with  it  to  find  out  how  well  it  cools  aquaria  Smile

 Thanks  Rahul,
 so  sweet  of  you  to  share!
 I  could  use  it  in  combination  with  a  auto  top-off  for  my  reef!  Will  surely  give  it  a  try  and  post  pictures!  actually  I  will  modify  the  design  to  suit  my  needs  -  Thanks  for  sharing!

 Hi
 
      The  idea  has  a  very  sound  technical  base  more  importantly  uses  a  vary  simple  principle  for  cooling  water.  From  what  I  have  understood  its  basically  increasing  the  speed  of  evaporation  hence  reducing  the  temperature  of  water  but  this  also  means  loss  in  quantity  of  water  hence  one  will  have  to  top  off  the  aquarium  little  more  frequently  also  I  feel  that  co2  loss  will  be  considerable  will  have  to  pump  a  lot  more.  
      But  I  guess  this  could  be  used  in  places  with  high  temps  as  it  is  definately  extremly  cost  effective.  Its  a  good  Idea  will  know  better  once  someone  tries  it  and  posts  their  experiences.
 
   Regards
      Harshal.

 Dear  aquascapes
                                  
                                     There  are  many  aquarists  from   all  parts  of  India  where  ambient  temp  are  high  who  are  looking  forward  to  your  results.
 
                      Please  keep  us  postrd.

 I  still  feel  that  the  way  an  air  cooler  cools  the  water  inside  is  damn  cool.  And  it  drops  it  much  lower  than  the  ambient  temperature.  If  someone  can  work  on  that,  I  am  sure  we  will  have  a  succesfull  model.
 
 Regarding  CO2  loss,  I  am  sure  we  will  have  to  adjust  with  that,  as  we  are  saving  big  bucks  by  not  buying  a  chiller.

 Hey  ame!
 Actually  what  my  plan  is  to  have  a  90mm  drain  pipe  with  two  elbows  attached  at  the  middle  of  the  pipe  and  the  fans  fitted  at  the  end  of  each  elbow  -  the  water  that  overflows  from  my  tank  into  the  sump  is  a  pipe  of  2"  diameter  which  I  will  cut  and  attach  a  sprinkler  with  to  go  in  the  drain  pipe  and  eventually  falling  in  the  sump  and  again  pumped  back  into  the  aquarium.  I'm  still  designing  the  final  layout  and  promise  to  post  once  i  have  done  it!
 I'm  not  sure  what  happens  to  the  planted  set-up  -  I'm  only  speaking  for  the  salt  hobby!

 Uh  oh!  Nauzer,call  me  a  pessimist  if  you  will,but  I  see  some  problems  with  the  sprinkler  thing(If  i  get  the  drift  of  your  idea).The  moment  you  add  a  sprinkler,water  flow  will  cut  down.Then,over  a  period  of  time  gunk  will  start  blocking  the  sprinkler  pores,gradually  cutting  down  water  flow.I  predict  two  out  comes:
 1.water  levels  in  the  show  tank  will  rise(and  overflow  if  you're  not  careful?)
 2.Sump  will  recieve  lesser  water  from  above,and  return  pump  may  run  dry.
 
 Solution  would  be  constant  supervision,and  periodic  dismantling  of  the  sprinkler  and  scrubbing  it.
 
 I  will  assume  your  overflow  is  well  protected  from  nosey  critters  who  like  to  take  a  jolly  ride  down  to  the  sump.If  not,one  of  the  critters  can  suddenly  block  the  sprinkler,and  above  two  scenarios  will  take  place  in  a  matter  of  hours.
 Then  again,I  might  me  wrong  in  my  understanding  of  your  idea.....post  pics/diagrams!
