 hi  all.......i  have  a  marine  tank  tats  been  running  since  10  months.........i  hav  a  wet/dry  trickle  filter..........i  recently  came  across  an  article  where  it  said  tat  the  bio  media  should  not  be  submerged  in  the  water  and  tat  the  water  should  just  fall  on  it..........is  it  true?......cause  the  bio  balls  in  my  tank  r  partly  submerged  and  partly  in  air

 I  was  wondering  if  u  wanted  to  fry  your  fish...
 
 As  for  your  Q..  The  bio  balls  are  supposed  to  be  out  of  the  water...  and  the  water  just  flows  over  them...

 Sachin,  the  logic  is  just  the  rich  oxygenated  water  that  flows  over  the  media.

 It  is  preferrable  that  the  bio  media  is  not  submerged  and  water  just  trickles  over  it  so  that  effective  nitrification  (  conversion  of  ammonia  to  nitrite  and  nitrite  to  nitrate  )  occurs  in  the  oxygen  rich  environment.
 
 The  most  preferrable  setup  would  thus  have  the  bio  media  in  an  always  exposed  to  air,  always  moist  condition.  If  that  can't  be  guaranteed,  having  a  small  part  of  the  media  submerged  will  not  do  much  harm.
 
 An  advantage  of  having  part  of  the  media  submerged  may  be  that  in  case  the  filter  is  switched  off  (  power  cut,  maintenance  etc  ),  the  bacteria  wil  be  alive  in  the  submerged  part  -  the  media  which  is  exposed  to  air  may  dry  up  and  lose  its  bio  filtration  capacity.

 ..which  is  why  i  prefer  ceramic  media  over  the  plastic  bio  balls.  The  ceramic  rings  remain  moist  for  a  longer  time  out  of  water,  due  to  the  natural  capillary  action.  The  bio  balls  tend  to  get  slimy  over  a  period  too.

 i  did  some  adjustments  and  made   sure  the  bio  balls  are  in  air  and  the  water  flows  over  them........but  how  do  u  get  the  water  to  flow  over  all  the  bio  balls?........there  seems  2  be  certain  areas  where  no  water  falls  on  the  bio  balls..........what  should  i  do?........also  i  use  ceramic  rings  as  bio  media....so  is  my  wet/dry  filter  effective?

 Wet  /  Dry  filters  are  amongst  the  best  choices  for  fish  only  marine  aquariums  as  they  are  highly  efficient  at  quickly  converting  fish  wastes  into  relatively  harmless  nitrates.  Frequent  water  changes  are  necessary  to  keep  nitrate  levels  down.  Using  a  mechanical  pre  filter  (  a  block  of  foam  /  sponge  )  before  water  enters  the  wet  /  dry  filter  will  further  ensure  your  nitrates  are  in  check  and  your  media  doesn't  get  clog  and  become  a  detritus  trap.  Make  sure  you  clean  the  pre  filter  frequently  to  maintain  filtration  efficiency!

 Depends  on  the  design  of  your  filter.  In  my  trickle  filter  i  used  a  plastic  tray  drilled  with  holes  above  my  bioballs.  The  water  from  the  tank  overflows  onto  this  tray,  and  then  drops  trickle  down  evenly  onto  all  the  bio  media.
 
 HTH

 i  to  am  using  a  plastic  plate  with  holes  and  the  water  drips  from  it.....but  still  i  dont  think  that  all  the  bio  balls  have  water  running  over  them.......also  my  ceramic  rings  r  submerged  in  water....is  that  the  right  thng?please  help  me  out  with  the  bio  balls-water  exposure  problem

 hi,
 
 sachin  i  am  posting  few  rough  sketch  with  description  of  my  newly  set  marine  tank  i  guess  this  might  help  you..  And  ceramic  ring  should  be  submerged  in  water  and  you  can  see  the  water  level  that  i  maintain  in  my  sump.  if  ths  snaps  and  description  doesnt  help  you  to  understand  lemme  know  i  will  post  the  live  snaps  of  main  tank  and  sump..
 
 bio  ball  
 
 
 
 sump  
 
 
 
       
                                                       regards

 Ceramic  rings  and  bio  balls  practically  serve  the  same  function  -  they  provide  a  substrate  of  increased  surface  area  for  bacteria  to  colonise.
 
 As  mentioned  before,  your  bio  media  (  bio  balls  and  ceramic  rings  )  should  preferably  be  in  an  out  of  water  moist  condition.  If  a  small  part  of  it  is  submerged,  it  is  not  a  problem.
 
 As  regards  your  water  not  flowing  over  all  the  bio  balls,  it  might  be  that  your  flow  rate  is  a  bit  on  the  lesser  side  and  the  volume  of  water  entering  the  filter  is  not  large  enough  to  trickle  through  all  the  media.

 well  i  understood....my  wet/dry  filter  has  the  same  setup.......i  use  both  ceramic  rings  and  bio  balls........but  if  i  increase  the  flow  rate  the  bio  balls  will  get  submerged....
