 These  are  the  picture  of  my  overflow  
 they  dont  work  as  well  as  i  had  planned  earlyer  
 I  dont  know  where  I  went  wrong
 Their  are  2  3/4  inch  blukheads  fitted  to  bring  the  water  back  to  the  system  
 and  their  is  a  3/4  inch  RPVC  pype  connection  connnected  to  a  4900  l/h  via  aqua  pump  
 and  a  1200  l/h  boyu  pump  seperatly  connected  to  the  UV
 these  2  should  be  returning  at  most  6100  l/h  
 and  all  that  I  have  read  and  which  has  been  confirmed  by  Gremlin  that  it  should  be  able  to  
 take  that  much  water  back  
 the  problem  which  is  coming  up  is  that  while  drainage  the  2  pipes  are  taking  Air
 I  would  really  appriciate  all  the  advise  that  I  can  get  
 Thanks

 I  can  see  in  the  3rd  pic  why  your  drain  pipes  are  sucking  air.  Are  they  making  gurgling  noise  too?

 I  think  you  need  to  bring  the  drain  pipes  up.  insert  a  pvc  pipe  in  each  of  the  drain  pipes,  also  cut  some  slots  in  the  pvc  pipes  so  you  dont  get  the  gurgling  noise.

 This  is  my  overflow.  The  2  fat  pipes  to  the  right  are  drain  pipes  and  skiny  pipe  is  return  pipe.  Ypu  cant  see  because  of  the  dirt  but  the  pipes  got  some  slits  cut  so  that  they  are  not  noisy.  Also  see  how  they  are  raised  and  not  flush  to  the  bottom  like  yours  is.

 where  do  you  want  me  to  insurt  pipes  
 and  what  sort  of  slot's  are  you  talking  about  
 the  kind  that  that  are  seen  in  the  readymade  overflow  system's  they  seem  like  they  are  segrigated
 also  I  have  made  some  changes  and  well   it  was  my  calculation  mistake  
 i  had  less  water  in  my  sump  and  i  had  to  increase  the  level  of  the  sump  as  well     it  is  now  very  close  
 to  being  overflowing  but  it  does  not  and  I  have  tested  the  power  failure  aspect  as  well
 and  the  sump  does  not  overflow

 Ok  I  can  see  where  it  is  going  
 But  i  think  I  can  do  that  but  my  theory  in  keeping  it  flat  was  that  I  was  going  to  introduce  some  
 filter  media  into  the  overflow  box   or  bioballs  or  something  
 and  use  it  as  a  wet-dry  or  something  
 since  I  am  new  I  am  still  a  lot  confused  as  to  how  to  go  about  it  
 Thanks  for  your  constart  advises  they  help  a  lot

 Welcome  to  our  madness   Very Happy  
 
 From  what  I  understand  from  your  pics,
 
 Have  you  considered  just  going  with  a  3000  lph  return  pump  instead?  Maybe  even  slower.  I  have  a  similar  sized  tank,  running  with   a  3000  lph  pump.  My  overflows  are  1.5  inch  though,  2  of  'em.
 
 Another  idea  is  to  have,  say  an  additional  1/2  inch  siphon  return  from  the  display  to  the  sump,  to  "assist"  the  overflow.  Place  the  inlet  of  the  siphon  high  up  the  display  tank,  such  that  even  if  the  return  fails,  the  sump  will  not  overflow.
 
   
 Good  luck

 Thanks  for  your  advice
 I  have  just  about  now  got  everything  down  to  a  Tee  
 the  overflow  is  working  properly  with  the  2  return  pump's  and  all  the  6100  l/h  are  doing  their  rounds  
 I  am  gonna  cconstantly  cheack  it  for  like  a  week  or  so  as   i  know  from  freshwater  experience  
 that  their  should  be  scope  for  something  to  go  wrong     
 and  as  Murfy  states  whatever  can  go  wrong  will  go  wrong  
 I  guess  I  have  to  be  vigilant  for  some  time  
 but  i  might  take  up  your  Siphone  idea  sounds  dooable  
 but  what  now  what  I  have  to  tackle  is  the  noise  factor  
 because  it  definately  is  pretty  loud  of  the  water  flow  
 
 Thanks

 Can't  help  you  much  with  the  noise  part.  Gremlin  seems  to  have  some  good  ideas  though.
 
 If  you've  got  it  working  well,  good  enough.  
 
 But  honestly,  if  you  feel  even  a  little  uncomfortable,  and  you're  not  gonna  like  this  ...  get  2'  overflows,  or  get  more  3/4'  's.  Cause,  if  anything  clogs  up  .......  you're  gonna  have  a  mess!  Better  now,  than  later.  It's  frustrating,  but  .......

 for  a  perfectly  silent  overflow  you  need  to  adopt  the  "Durso  standpipe"  design,  Google  it  and  you  will  get  some  pics.
 Lot  of  bangalore  guys  are  using  this  and  have  had  no  problems  till  date.
 If  you  can  post  a  sketch  of  your  design  ..  i  may  be  able  to  help  you  out  with  the  design.

 If  i  have  read  the  images  correctly,  you  are  literally  sucking  water  from  your  tank  into  your  drain..  am  i  right?  if  this  is  the  case,  then  there  wont  be  surface  skimming  and  your  tank  wont  perform  to  your  expectations.  Surface  skimming  is  a  must  for  well  maintained  tanks.  
 
 To  correct  the  noise,  which  you  will  have  for  sure  currently,  use  need  a  Durso  Model  Stand  pipe  as  rahul  mentioned  -easy  to  do  :  take  a   PVC  pipe  that  is  about  3"  less  than  the  height  of  the  water  level  in  the  tank,  add  a  "T"  to  it,  one  end  of  a  "T"  add  an  Elbow  "L"  pointing  downwards  and  at  the  other  end  add  a  dummy  with  a  small  hole  drilled  in  it.  Do  this  for  both  the  drains  and  you  will  be  set  with  min  air  and  min  noise.
 
 Or  if  you  want  perfection,  you  are  do  the  "Fail  Safe  Over  Flow  System"  as  in  Reefcentral-DIY  Section.  Works  Perfectly  without  any  issues.  Absolutely  no  Noise  and  performs  the  best.
