 PLEASE  CHECK  THE  REVISED  FILTER  FROM  PAGE  3
 
 Hi  People,
 After  reading  and  contemplating  about  canisters,  I  couldnt  keep  myself  from  DIYing  one.  It  took  a  lot  of  time,  I  was  too  busy  sometimes,  so  the  process  stood  on  halt  for  long  periods.  Thats  why  I  wasnt  able  to  take  the  pics  then.
 I  starting  plotting  the  cheapest  ways  possible  and  posted  some  kiddish  plans  earlier,  that  used  buckets  /  some  odd  containers,  but  neither  seemed  good  enough  for  a  big  canister.  
 Finally  I  grabbed  some  PVC  stuff  and  started  off  with  the  project.   As  I  was  totally  a  noobee  in  DIY  stuff,  I  found  it  really  complex  to  get  the  stuff  around,  things  are  called  differently  in  the  local  market,  its  pretty  difficult  to  communicate  with  those  shop  fellas,  when  you  ask  for  something,  their  lil  brains  starts  functioning  in  a  different  way,  they  ask  the  purpose(this  is  where  all  goes  wrong),  if  its  something  different  than  usual(aquarium  stuff  is  highly  unusual  for  them),  their  minds  stop  at  that  instant,  they  are  confused  and  they  dont  even  agree  upon  giving  you  the  thing  even  if  they  have  it  Sad  .  In  this  situation  I  got  acquainted  to  a  LHS(local  hardware  shop)  keeper  who  helped  me  a  lot  with  patience,  understood  all  the  descriptions  of  stuff  I  gave  and  provided  with  all  what  I  needed.  Thanks  to  this  guy,  my  project  got  going.
 
 The  mechanism  is  pretty  simple  as  that  of  Eheim  classic  series(for  example)  -  Water  gets  siphoned  into  the  canister  from  bottom,  passing  through  various  media  moves  upwards  into  a  pump  situated  at  the  top  that  throws  the  water  back  into  the  aquarium.....  this  idea  was  also  adapted  by  Mr.Perikaruppan  (I  also  thank  him  for  clearing  a  few  of  my  doubts  at  the  beginning  of  the  project).
 
 So  here  it  goes.....
 
 PLEASE  CHECK  THE  REVISED  FILTER  FROM  PAGE  3
 The  Canister
 
 
 
 
 
 Materials  used:
 18"  tall  4"dia  PVC  pipe  with  4mm  gauge
 4"dia  slip  type  end  cap  for  base
 4"dia  threaded  socket  with  lid  for  the  top
 3/4"dia  PVC  pipe
 A  couple  of  1/2"  ball  valves
 4"  'O'  Ring  to  make  the  container  air  tight
 A  Good  quality  'Chinese'  air  cooler  pump  750lph
 Some  odd  numbers  of  Nozzles(1/2"),
 couplings(slip  type,  slip  type  to  inner  threading  type)
 elbows
 1m  1/2"dia  multipurpose  hose  pipe.
 PVC  cement,  Araldite  and  silicon
 
 Tools:
 Hacksaw  blade,  Drill(with  various  sized  bits),  dremel,  paint  brush(for  applying  adhesives),  Sharp  knife,  pliers,  scissor,  file.
 
 All  the  above  combined  gave  7  simple  parts  that  can  be  assembled  and  removed  whenever  needed  with  a  little  effort.
 
 1-The  Canister
 2-Lid  with  a  pump
 3-'O'  Ring
 4-Controllers
 5-U-bends  to  go  into  the  tank
 6-Strainer
 7-Spray  bar
 
 A  3/4"  hole  was  drilled  at  the  bottom  of  canister  for  inlet,  which  was  made  pasting  pvc  couplings,elbow  and  nozzle  together.  
 
 The  'O'  Ring  is  an  essential  part,  that  keeps  the  system  from  leakage.  Luckily  I  was  able  to  find  one  which  is  used  in  heavy  machinery  for  gas  compression,  pretty  expensive  though....
 
 I  was  looking  for  union  ball  valves  which  I  couldnt  find,  so  I  had  to  settle  with  the  normal  ones.  which  I  permanently  fixed  using  adhesives.  These  valves  can  be  closed  while  cleaning,  hence  they  save  me  from  priming  it  every  time  I  open  the  canister.  
 
 
 Further  am  looking  for  to  get  a   pair  of  p.p.  compression  fittings,  which  are  again  a  costly  deal  and  can  increase  the  cost  of  canister  by  30-40%.These  will  provide  ease  in  attaching  and  detaching  the  hose  pipe.  Now  I  have  to  wrestle  a  bit  Wink   for  pulling  them  out  from  nozzles.
 
 I  was  thinking  of  using  a  5  or  6"dia  pipe  for  canister  but  they  being  very  rare  and  their  lids  that  are  not  found  around,  I  didnt  had  patience  to  search  them  all,  so  went  for  4"...  will  use  a  bigger  diameter  for  next  filters  I  make.
 
 
 The  pump  has  a  slip  type  nozzle,  so  I  drilled  a  1/2"  hole  on  lid,  permanently  fixed  the  nozzle,  the  pump  can  be  pushed  in  to  attach.  this  gives  an  advantage  of  removing  the  pump  whenever  needed  for  cleaning  the  propeller  n  other  parts  inside.  The  electrical  chord  passes  through  a  3-4mm  hole  on  the  same  lid,  hole   is  temporarily  sealed  using  silicon(so  that  later  the  pump  can  be  removed  for  claiming  guarantee  if  needed).
 
 
 The  spray  bar  and  the  strainer  attached  to  the  U-bends
 
 
 Note-
 -This  filter  is  for  my  30g  planted  tank,  thats  why  used  a  pump  with  minimum  output.
 -PVC  cement  should  be  only  used  for  pvc-pvc  joints,  it'll  not  fasten  pvc  on  any  other  mateial,  so  araldite            was  used  for  pvc-plastc  joints.
 -Dremel  was  an  additional  tool  used  to  make  quick  n  clean  cuttings,  hacksaw  can  be  used  otherwise  for  the  same  and  later  the  surface  or  edges  can  be  filed  and  sanded  to  give  a  neat  look.
 
 As  of  any  equipment  this  has  flaws  in  itself:
 1-Its  too  narrow
 2-The  lid  has  to  be  tightly  replaced  after  opening,  to  avoid  leaks
 3-To  open  the  lid  we  have  to  make  over  a  dozen  rotations!  but  yet  can  be  done  once  or  twice  a  month.
 4-The  base  cap  is  round  headed,  so  am  keeping  a  4"  coupling  under  it  for  now.
 
 I  have  just  completed  the  canister,  which  is  being(and  will  be)  tested  for  some  more  days,  couldnt  wait  to  post  the  pics....so  started  the  thread.
 
 I  havent  decided  about  the  media  yet....I  guess  I'll  use  non-fancy  bio  media,  the  pot  scrubs,  filter  floss  and  sponge  of  less  density...thats  it  for  now.
 
 At  the  end  I  can  say.....It  was  a  great  experience  creating  a  thing  I  havent  used  till  now,  finally,  I  have  done  it  atlast!  The  HMC(home  made  canister)  or  Primitive  canister...thats  what  I  call  it.
 
 Looking  forward  to  know  your  views.

 Awesome  filter  !  It  is  a  total  DIY  and  almost  everything  is  PVC  stuff...  One  question  :  Was  the  pump  you  used  and  out-of-water  pump  or  the  ordinary  submersible  pumps  ??

 Nice  job  Hamza.
 
 I  made  a  similar  one  5  yrs  back  and  it  is  now  lying  in  my  terrace.
 The  problem  I  found  with  this  setup  is  that  the  quality  of  fittings  we  get  in  India  is  poor.
 Eventually  it  leaks  as  these  fitting  are  not  designed  for  frequent  opening  and  closing.  
 These  are  fittings  used  in  sanitary  lines  and  typically  they  are  not  opened  for  years.
 
 So  Good  luck.  I  was  personally  never  at  peace  at  office  thinking  this  might  leak  when  I  am  not  at  home  and  office  becomes  my  permanent  home.
 
 Well  done  and  nice  pics,  nice  post.
 
 regards

 Hi  Hamza
 
 This  is  one  of  the  best  DIY  designs  for  an  External  Filter  that  i  have  seen.  Great  Stuff.....excellent  detail,  im  sure  quite  a  lot  of  people  are  going  to  benefit  from  this  ....  Will  definitely  try  this  when  i  get  some  time   Thumb Up

 Excellent  Job  !!!
 My  only  concern  is  after  you  clean  the  hose  pipes  say  10-15  times  the  joint  where  you  fix  the  hose  pipe  will  become  loose.  This  is  critical  because  if  that  snaps  out,  you  are  going  to  drain  all  the  water  into  your  room.  A  quick  fix  to  this  can  be  to  add  one  of  those  pvc  screw  cap  and  threaded  pipes.  you  can  tighten  the  cap  over  the  hose  pipe  securely.  This  is  how  all  the  external  canisters  are  built.  Also  I  will  suggest  to  raise  the  water  inlet  inside  the  aquarium  to  about  half  the  height  of  aquarium  so  that  even  if  there  is  an  accident  the  filter  won't  drain  the  tank  completely.
