 You  might  want  to  increase  the  height  of  the  sump  and  put  a  refugium  in  there.  
 And  a  clownfish!!  Can't  imagine  a  reef  without  one.                

 
 Hi  Pradeep!
 The  height  of  the  sump  is  limited  by  the  stand  I  have  already  made....even  an  inch  more  and  my  hands/skimmer  cup  will  not  be  able  to  get  in/out.One  of  the  main  reasons  I'm  keeping  the  whole  set  up  low  is  for  a  better  view  while  seated  on  a  nearby  sofa.A  low  set  up  also  means  easier  maintainance.The  previous  set  up(5x2x2  main  +  4x1.5  x1.5  sump)  had  a  total  height  of  6  feet!Sitting  on  the  nearby  sofa,you'd  be  lucky  to  get  a  ventral  view  of  the  fish....or  admire  the  wood  work  of  the  stand.A  lower  height  also  reduces  the  head  load  on  the  return  pump.

Lighting:  1x150W  20k  mh,  2x20W  actinics,  2x36w  6500k  Pll's.                  

 Why  do  you  need  to  waste  your  money  on  actinics  when  you  are  already  using  or  going  to  use  a  20000*K  MH?  I  would  rather  suggest  a  10,000*K  Hi-Pl  Smile

 the  amount  of  water  circulation  you  mention  needs  to  be  controlled  or  you  will  end  up  seeing  the  mushrooms  flying  around  the  tank!

 can  the  skimmer  that  you  mention  handle  such  a  high  flow  rate?  NO!  See  there  is  a  specification  or  a  water  level  mark  on  the  skimmer's  reaction  chamber  -  you  should  aim  at  pumping  the  water  atleast  to  that  level  that  is  about  it  we  need  a  correct  flow  rate  not  high  flow  rate  for  the  skimmer

 I  would  advise  you  to  keep  a  heater  always  on  at  25*C  if  you  are  riding  a  horse  without  reigns  you  tend  to  loose  balance!

Water  flow  in  order  -  First  in  an  empty  baffle,  then  through  the  skimmer,  then  some  mechanical  media,  carbon,  the  refugium,  finally  the  return  (have  space  here  if  for  some  uv  sterilizer).                  

 the  order  here  should  be  overflow  -->  pre-filter  -->  skimmer  -->  mechanical  filter   (save  the  carbon  for  making  carbon  copies  of  your  bills!)  -->  baffle  -->  return  and  if  you  are  incorporating  a  fuge  along  I  would  strongly  urge  you  to  plumb  it  in  seperately   Smile

1)  Fill  it  with  (self  created)  coral  sand  and  try  a  dsb.  
 2)  Fill  it  with  bigger  sized  coral  sand  (above  3mm)  and  try  my  hand  at  keeping  some  type  of  macro-algae  rock.  
 3)  DIY  ATS  (very  low  probability).                  

 all  the  possible  pros  and  cons  are  already  discussed  here  on  the  fourms  so  I  guess  you  will  have  to  ultimately  decide  and  take  the  decision  yourself  as  to  what  will  be  the  best  suited  for  your  set-up  I  would  however  if  I  had  to  consider  the  above  (though  I  never  got  the  ATS  term  correct  and  presume  you  want  to  get  into  the  anti-terror  squad!)  would  tick  on  the  -  none  of  the  above  box!
 @Murthy,
 you  got  mail!
 for  the  rest  of  you  who  are  following  the  thread  I  have  not  mailed  a  top  secret  blue  print  to  murthy  but  just  some  suggestions  after  a  telephonic  conversation.  So  stay  tuned.........Murthy's  reef  will  be  right  back!

 M.h  would  be  used  for  a  short  duration  and  not  the  entire  photoperiod.

 Yes,  that  is  why  i  am  directing  the  return  in  two  places,  and  just  adding  one  in-tank  powerhead  again  with  two  outlets,  all  this  to  maximise  flow  in  all  areas  in  the  tank.

 Again,  yes!  I  checked  that  and  going  for  the  Azoo  1800L/h  powerhead.

 Shouldn't  the  water  first  go  into  the  skimmer  without  any  'filtering'?  And,  didn't  know  you  do  not  promote  carbon  usage,  or  wait  i  think  you'll  say  that  use  it  only  when  needed  right?  Smile

 Ok,  so  if  in  a  similar  setup,  what  would  YOU  do,  IF  the  fuge  is  inline?  and  what  would  you  suggest  to  do  of  the  fuge,  given  the  aim  being  to  reduce  the  nitrate\phosphate  levels  to  zero  or  close?
 Thanks,
 amod.

 amod,
 you  are  right  I  said  use  it  with  caution  (yes  I  do  not  use  carbon  in  any  of  my  tanks  and  will  only  use  it  if  I  have  to  sometimes  'adsorb'  something).
 and  I  already  told  you  that  if  I  were  you  I  would  plumb  in  the  fuge  seperately
