 Hi,
 I  am  planning  to  purchase  an  eheim  2217,  when  enquired  with  the  dealer  he  said  that  it  comes  with  five  blue  coarse  pads,  one  carbon  pad  and  one  fine  pad  and  it  does  not  have  a  separate  medium  for  bio-filtration,  he  also  mentioned  that  this  medium  is  quite  enough  and  no  separate  bio-filtration  medium  is  needed.
 When  looking  for  the  details  in  web,  All  the  Eheim's  sold  in  US  comes  with  EHFISUBSTRAT  (bio-filtration).
 Should  I  buy  EHFISUBSTRAT  if  I  need  bio-filtration?  
 If  so  what  would  be  its  maintenance  cycle  and  life?  
 is  there  any  cost  effective  alternative  for  bio-filtration  other  than  EHFISUBSTRAT?
 What  is  the  maintenance  cycle  of  coarse  pads?
 
 Thanks

 Hi  Sen,
 
 I  am  using  EHEIM  2217  for  more  than  a  year  now  for  my  4'/1.5'/1.5'  planted  aquaria.  Yes  it  is  coming  with  five  blue  coarse  pads,  one  carbon  pad  and  one  fine  pad  and  it  does  not  have  a  separate  medium  for  bio-filtration.  
 
 I  have  replaced  3  blue  coarse  pads  and  fill  the  gap  with  small  ceramic  tubes.  It  is  giving  me  good  Bio  Filtration.  You  can  use  anything  you  want  like,  ceramic  tubes,  sintered  glass,  Nylon  mesh  (which  we  are  using  to  clean  utensils)  the  choices  are  endless.
 
 Please  remove  the  carbon  pad  after  a  week.  
 
 I  clean  the  filter  once  in  3  months.  Just  rinse  them  in  siphoned  aquarium  water  to  get  rid  of  derbies.
 
 But  I  must  say  that  it  is  a  very  good  buy.
 
 regards

 Hi  ,
 Thanks  for  the  info.
 I  have  some  ceramic  rings  and  bio  balls.
 The  bio  balls  are  1  inch  in  dia.
 Can  I  use  both  ceramic  rings  and  bio  balls  as  filtration  medium?
 If  I  want  to  use  both,  should  it  be  separated  by  a  coarse  pad?
 Which  one  is  better  "bio-filtration  medium"  ceramic  rings,  bio  balls  or  the  coarse  pad?
 Which  layer  should  the  ceramic  rings  occupy,  the  mechanical  filtration  layer  or  the  bio-filtration  later?
 
 Thanks

 im  deciding  between  which  filters  to  buy  as  well.
 
 the  Eheim  2217  is  apparant  the  popular  choice  but  is  a  bit  expensive  compared  to  the  Dolphin  canister  filters  (C  500  -  C  1600  series)
 
 I  have  never  used  an  external  filter  before  so  i  really  dont  know  much  about  media,  performance,  etc.
 
 I've  PM'd  the  rates  i  got  from  a  suppplier  in  Chennai
 
 Need  suggestions  experts!

 I  have  had  an  Eheim  2213  running  for  almost  8  years  now,  without  any  problems.
 Dolphin  is  a  relatively  new  product,  so  I'm  not  sure  if  anybody  would  be  able  to  vouch  for  its  quality.  
 I  have  seen  a  few  others  in  the  market  like  Jebao  and  Atman  but  again  im  not  sure  about  their  dependability.

 Hi  supershaji,
 after  lotsa  research  I  have  settled  down  for  eheim..  mainly  because  of  their  proven  track  record  and  It  is  german..
 Please  stay  away  from  cheap  chinese  stuff..
 
 I  heard  that  Dolphin  is  a  good  product  but  it  consumes  40W  of  power  for  1000L/Hr  flow  so  sure  of  having  heating  issues  (Eheim  consumes  20W,  just  half  of  it  and  2217  has  a  thermal  switch  which  stops  the  motor  when  heated  and  restarts  once  it  cools)  ,  and  heard  it  has  issues  during  power  cuts..
 
 people  claim  that  Azoo  is  also  good..  but  I  am  not  able  to  see  any  good  reviews  on  net..

 Thanks                

 
 ehfisubstrat  is  a  very  good  biological  filter  media.VERY  expensive.so,it  will  depend  on  what  live  stock  you  have,and  if  its  worth  the  investment.And  strictly  speaking,eheim  recommends  replacing  ehfisubstrat  after  a  certain  period(i  think  after  three  years)...but  boiling  the  media  should  be  ok  for  reuse.
 slightly  cheaper  is  ehfilav.If  you  are  planning  on  keeping  african  cichlids,crushed  coral  also  makes  wonderful  media.
 
 Initially,even  I  was  under  the  impression  that  ceramic  rings  are  biological  filtration.After  a  thorough  review,turns  out  ceramic  rings  are  mainly  mechanical  filtration(biological  being  a  minor  part).Bioballs  are  biological  filter  media,but  better  suited  for  larger  volume  filters,wet-dry  trickle  filters.
 so  in  conclusion,these  would  be  my  options  for  2217,prioritised  by  what  you  want  to  keep:
 1.ehfisubstrat
 2.ehfilav
 3.crushed  coral(only  for  africans/marine)
 4.filterpads  alone.
 You  should  use  one  layer  of  ceramic  rings,about  2  inches  layer  in  the  bottom  most  part  of  2217.
 A  note  on  ceramic  rings:azoo  has  a  ceramic  ring  product  that  is  made  of  sintered  ceramic,I  believe  that  makes  for  very  good  biological  filtration  too.Try  it  out!  Smile

 Dolphin  has  issues  with  power  cuts??  dang,  we  have  so  many  here  in  Hyderabad  since  the  govt  changed!
 
 So  i  guess  i'l  just  do  some  more  research  to  satisfy  myself  and  then  save  sum  more  moolah  to  buy  myself  an  Eheim.
 
 by  the  way,  my  tank  holds  approx  300  ltrs  (approx  3.5'x2'x2'  in  dimention).  What  kind  of  an  Eheim  filter  would  suit  this  tank?
 
 thanx  in  advance!  Smile

 Hi  All,  
 Is  anyone  using  a  Hydor  or  a  Fluval  cannister  ?  Eheim  is  available  in  Dubai  but  a  bit  too  expensive  compared  to  Hydor  and  Fluval.
 any  advise  is  welcome  !  
 Thanks
 Jaideep

 Hi  Jaideep,
 I  saw  a  guy  hunting  for  impeller  for  his  1  year  old  Fluval..  I  think  getting  spares  for  fluval  is  difficult  in  India  (This  is  my  guess)..
 
 shaji..  when  you  see  the  Eheim  specs  all  the  calinsters  are  rated  for  a  UPTO  volume..
 i.e  2217  can  be  used  for  a  tank  upto  160(if  I  remember  the  figure  correctly  !!!)..
 but  if  you  have  a  tank  with  volume  <  160..    the  flow  can  be  controlled  (By  using  the  double  tap  valves..  I  guess)..
 
 gurus  am  I  right  at  this  ??  for  controlling  the  flow  do  we  use  double  tap  valves??
 
 thanks

 Jai,
 
 Hydor  is  amazing  stuff.  The  external  series.  I  know  a  few  hardcore  reefers  in  the  USwho  use  them.  They  trust  them  with  thousands  of  dollars  worth  of  corals  and  fish.
 
 Fluval  aint  great  stuff.  Seen  it  failing  a  couple  of  times,  and  struggled  to  get  it  ready.  
 
 Eheim  rocks.  German  technology.  I  havent  seen  many  ppl  complain  abt  Eheim.  The  best  part  is  that  power  consumption,  noise  levels,  and  heat  is  also  minimum  in  an  Eheim.
