 Dear  Friends,
 
 Here  is  a  summer  special  for  you,  who  do  not  wish  to  buy  a  Chiller,  would  like  to  stick  to  DIY  stuff.
 
 Required  essentials  (  I  am  using  it  for  a  20G  planted  Tank)
 
 1) Power  head  400  L  and  above
 2) Water  tube  ¼”  (4  to  6  meters  )
 3) thermocol  case  box   (45X60  cm)
 4) finally  the  essential  ingredient  (ICE)
 
 Simple  instruction
 
 Make  2  holes  on  the  top  of  the  thermocol  lid  for  the  inlet  and  outlet  Insert  the  tube  from  the  bottom  of  the  lid  and  roll  the  balance  inside  the  box.
 Connect  1  end  to  the  power  head  outlet  and  leave  the  other  one  in  the  tank
 Fill  ½  of  the  thermocol  box  with  ice  and  switch  on  your  power  head.
 Wait  for  an  hour  and  check  your  temperature.   It  will  last  for  8  hrs  in  the  morning  and  more  than  12  hrs  in  the  evening.
 
 Here  are  some  pictures

 Hi  Ram,
 
 I  am  not  clear.  You  are  taking  the  cold  water  (ice)  from  thermocol  box  to  tank.  But  there  should  be  another  outlet  from  tank  to  thermocol  box  also.  Otherwise  tank  will  be  overflow.
 
 May  be  I  didn't  understand.  Never  mind  please.

 Dear  Abhis,
 
 I  am  not  taking  the  cold  water  from  the  thermocol,  the  water  is  getting  circulated  within  the  tube,  there  is  an  inlet  and  outlet  to  the  tank,  hence  there  is  no  questiion  of  overflowing.
 
 Regards
 Ram

 Mud  Pots  if  kept  in  front  of  a  breezy  window  will  have  atleast  29deg  temp  of  water.  
 
 We  drink  water  from  earthen  pot  placed  in  ront  of  a  breezy  window  Smile

 Jabba:  Mud  pots  work  on  the  principle  of  capillary  action  &  evaporation.  So  the  temperature  of  water  is  relative  to  atmospheric  temperature.  It  will  be  about  5  degrees  cooler  than  the  ambient  temperature.  When  we  drink  water  from  a  mud  pot  it  is  the  perception  of  being  cold  as  it  is  colder  than  the  temperature  outside.  Another  thing  is  the  temperature  of  water  in  a  mud  pot  is  most  efficient  in  quenching  our  thirst  (whatever  the  temperature  of  water)  as  the  feeling  of  satisfaction  is  also  perceptive.
 
 If  you're  thinking  about  using  it  for  your  tanks,  it  is  quite  a  good  idea.  Just  that  it  could  be  a  pain.  You  have  to  place  the  pot  on  a  bed  of  sand  for  maximum  efficiency.  And  a  mud  pot's  ability  to  cool  water  is  finite.  It  loses  that  ability  as  minerals  in  water  start  clogging  the  pores  of  the  pot.
 
 A  cooling  fan  IMO  works  on  the  same  principle  as  a  mud  pot,  just  a  different  mechanism  -  no  capillary  action,  only  evaporation  due  to  surface  agitation.  So  it  would  be  much  easier  to  use  a  fan...  but  that's  just  my  opinion.

 I  used  roofing  clay  tiles  in  my  shrimp  tank.  The  temperature  in  my  tank  shows  27  *  Celsius.
 
 See  this  Link
 
 I  tied  some  Riccia  into  it.  And  my  shrimp  loves  to  hide  into  it.

 @Ganesaa:  I  don't  think  jabba  is  talking  about  using  a  mud  pot  inside  the  tank.  I  think  he  wants  to  use  it  as  a  chiller  externally  &  circulate  water  through  it.  keeping  terracotta  in  the  tank  will  not  have  a  cooling  function.
 
 @ram_rama:  That's  a  nice  DIY.  Are  you  using  metal  tubes  inside  the  tank?  Wouldn't  that  give  better  cooling?
 
 PS:  didn't  we  meet  at  Senthil's  place  the  other  day?  Or  am  I  mistaken?

 Dear  Athreyan,
 
 Thank  you
 
 Yes,  we  have  met  at  Senthil's  place,  
 
 I  thought  of  using  metal  tube  for  the  cotact  of  chilled  water  in  the  ice  box,  expected  the  cooling  effect  will  be  very  quick  and  the  ice  may  not  last  longer,  with  a  plastic  tube  the  cooling  will  be  gradual.
 
 Regards
 Ram

 This  has  been  discussed  before  on  the  forum.  While  it  will  work  in  a  pinch,  it  will  be  tedious  to  produce  enough  ice  for  more  than  a  small  tank.  Also  the  your  freezer  will  consume  more  electricity  to  freeze  the  ice.  People  have  even  run  a  mini  fridge  with  the  tubing  coiled  up  inside  to  cool  the  water.  But  this  also  will  put  a  strain  on  the  fridges  compressor  and  will  burn  quite  a  bit  of  electricity.
 
 A  good  solution  would  be  cooling  fans  +  tube  coil  running  through  ice  kept  in  thermocol  box  and  thermocol  box  kept  in  mini  fridge  uncovered.  Ice  made  inside  your  main  freezer.
 
 Hmmmmm  Im  getting  curious  to  see  how  that  would  work

 Ice  can  be  preserved  for  very  long  period  if  it  is  mixed  with  salt.

 Yup  salt  helps.  It  will  become  half  melted  slush  though  also  known  as  freezing  mixture
