 Can  anybody  tell  me  the  reviews  of  Atman  filters???  Reliability  and  easibility.??
 This  one  is  a  2400lts/hr  with  UV.  Not  able  to  remember  the  model  number.
 Secondly,  Does  UV  help??

 With  your  size  of  a  tank,  you  should  go  in  for  a  pond  filter.  rate  of  flow  will  range  between  7000  to  15000  l/hr  or  even  more  if  you  want.  You  will  have  to  order  one  from  abroad.  You  will  find  a  lot  of  choices  if  you  GOOGLE  for  it.  They  are  even  available  on  Amazon.com.  Just  keep  the  customs  duty  (34%)in  mind  while  ordering  from  Amazon  (if  you  plan  to  order)

 Even  you  can  DIY  it  with  a  good  quality  water  pump.  The  capacity  should  of  course  exceed  7000  liters  p/h.

 You  are  somewhat  right  Saurabh,  but  the  only  problem  with  that  would  be  that  you  cannot  leave  it  on  24x7.  You  would  need  to  monitor  switching  on  and  off.

 OASE  has  good  pond  filters.  The  main  dealer  is  in  Bangalore.  Rufus  was  also  dealing  with  OASE  filters.  His  contact  is  9845039631.
 
 I  hope  I  got  OASE  right!  Very Happy  
 
 Since  you  have  already  ordered  an  Eheim  there's  not  much  we  can  change.

 Hello  Smile  
 First  of  all  you  have  a  INSANE  tank  nitishi..Smile
 big  time  envious  LOL
 You  can  also  look  at  adding  a  external  UV  tube  with  your  external  canister  filters  .
 Get  a  good  big  one  like  a  36  watt  UV  or  something.  Can  also  be  hooked  up  to  a  simple  powerhead.
 2950  lt/hr  accordig  to  me  is  not  going  to  be  enough  sir  nitishi.  You  should  atleast  have  2  times  the  turover  of  the  volume  of  your  tank  per  hour  at  the  very  minimum.
 look  at  adding  a  5000-8000  lt/hr  pump/filter  as  well  if  possible  .  
 Cant  get  over  your  tank  specs  hehehehe  .  Please  do  post  a  pic  for  us  Smile
 Dying  to  see  that  monster  Smile

 When  you  have  spent  so  much  on  the  tank  and  everything  else,  invest  in  a  1  KVA  servo  stabiliser  too.  It  costs  about  3.5K.  That  will  protect  your  equipment.
 
 I  use  a  1  KVA  servo  stabiliser  for  my  tanks  as  I  have  6  Eheim  filters  running,  all  my  lights  run  through  the  stabiliser.  When  voltage  is  very  low  the  rotor  keeps  banging  on  the  sides  and  gets  damaged,  the  servo  stabiliser  will  protect  you  from  damage.

 Sorry  for  the  Hijack
 
 @Madan
 For  running  the  filter  alone  wouldn't  an  online  /  line  interactive  UPS  of  smaller  capacity  suffice?  Wouldn't  that  give  you  a  safety  margin  for  power  failure?

 I  am  not  worried  about  power  failure.  The  Pumps  stop  and  there  is  no  damage.
 
 My  worry  is  low  voltage,  in  the  region  of  140  V  or  less  which  we  sometimes  end  up  with  for  a  few  hours.
 
 Secondly  this  low  voltage  damages  my  MH  in  no  time,  that's  why  I  have  a  1  KVA  rating  servo  stabiliser.

 Hi  Nitish,  
 
 I've  used  the  CF-2400  (@2400lph)  excellent  performance,  but  had  to  be  replaced  by  an  Eheim  2260  after  2.5  yrs.  (leak  problems).
 
 For  a  beginner  &  amateur  -  it  will  be  tedious  to  open  for  servicing.  Levers  can  break,  if  not  careful.  
 
 Spares  availability  â€“  poor.
 
 In  short  â€“  excellent  performance  &  poor  on  reliability.

 UV  is  beneficial  for  outdoor  ponds  /  FW  aquariums.  UV,  along  with  destroying  algae  spores,  also  kills  beneficial  bacteria.  It  should  be  used  with  caution  on  indoor  FW  Aquariums.  Its  use  in  marine  aquarium  is  out  of  context  here.

 Hi  Sumant,
 
 I  don’t  see  any  issue  is  keeping  a  7000lph  or  even  15000lph  pump  ON  for  24x7.  If  it  is  meant  for  biological  filtration  it  has  to  be  on  always.
 
 I  completely  understand  power  outages  are  likely  &  that’s  something  not  in  our  control,  but  if  you  wish  to  have  100%  uptime,  opt  for  an  inverter.

OASE  has  good  pond  filters.  
 Since  you  have  already  ordered  an  Eheim  there's  not  much  we  can  change.                

 
 Hi  Madan,
 
 That’s  very  true  they  are  only  good  as  POND  filters.  Smile  
 
 One  of  my  clients  insisted  that  he’d  get  a  filter  for  his  aquarium  from  abroad  &  he  got  an  OASE  FILTOCLEAR  6000  with  AQUAMAX  3500.  I’d  educated  him  on  media  option,  but  he  was  still  willing  to  try.
 
 We  installed  the  filter  &  it  took  over  10  days  for  the  water  to  clear  out.  Â Well,  at  the  same  time  at  18”  depth,  the  water  appeared  crystal  clear  the  in  2  days.  But  through  5’  depth  &  10.5’  length  vision  was  very  poor.
 
 Reason  â€“the  canister  only  houses  Fine  &  Coarse  Sponge  in  alternate  rings    â€“  STACKED    &  water  flows  over  various  media  simultaneously  outward  >  inward  flow  &  that  the  primary  reason  for  the  longer  duration  in  clearing.  My  observation  -  the  filter  partly  served  the  purpose  &  helped  in  circulating  the  water,  this  circulation  in  turn  lodge  fine  particles  into  the  substrate.
 
 On  day  7  -  I  opened  canister  &  stuffed  the  vertical  cavity  in  the  center  with  finer  sponge,  than  the  existing  one,  &  that’s  when  we  noticed  the  water  clearing  out  much  faster.  However,  this  drops  the  output  of  the  filter  by  ~10%  &  is  not  recommended  for  proper  functioning  of  the  filter,  especially  when  we  wring  the  media  using  the    external  handle  ,  hope  you  understand  my  perspective.
 
 Second,  the  filter  has  two  separate  components  â€“  Pump(Aquamax)  &  Canister(Filtoclear).  The    pump  has  to  be  kept    submerged    in  the  main  system  which  delivers  water  to  the  canister.  The  Pump  housing  does  pre-filtration  for  debris  size  up  to  8mm,  which  leaves  a  scope  for  small  fish  such  as  tetras,  Ottos,  etc.  to  get  sucked  in.  We  need  to  again  cover  this  pump  with  yet  another  finer  net  /  mesh  to  prevent  this.  
 
 FILTOCLEAR  &  BIOPRESS  SET  are  the  sealed  canisters,  all  other  models  are  based  on  filter  overflow  method.
 
 All  in  all,  these  filters  may  be  good  for  ponds,  but  not  for  Aquariums  that  require  viewing  from  the  side.  The  canister  models  do  not  have  layered  media  approach  &  options  for  alternate  media.  The  pump  pre-filter  in  not  suitable  for  small  fishes.  There  are  other  models  â€“  BIOPRESS  SET  that  has  space  for  optional  media,  but  again  it’s  not  layered,  which  I  look  at  as  a  big  drawback  on  both  models.
 
 2.5  times  more  expensive  than  Eheim,  so  I’d  rather  go  for  two  Eheim’s  that  is  meant  for  all  glass  aquariums  Smile  &  yet  have  all  the  available  option  required  for  a  maintaining  a  healthy  FW  setup.  With  Eheim,  I  can  still  opt  for  alternate  media  &  use  it  on  a  pond  Wink
 
 Having  spent  the  money  on  an  OASE,  I'm  now  working  on  options  to  redo  the  setup  minus  the  Canister  to  get  effective  filtration.  Maybe,  in  aquarium  partition  with  over  flow  or  something.     Rolling Eyes   Unsure   Crying or Very sad
