 Have  set-up  a  70G  tank  15  days  back.  I  have  been  monitoring  the  water  parameters  regularly  (once  in  2   days).  The  readings  have  been  identical.  No2  is  0  and  No3  is  10-25  ppm,  Ammonia  is  0,  Gh  is  6-10  deg,  Kh  is  between  3-6  deg  and  Ph  is  7.2.  
 
 Along  with  the  new  2217  (foam,  biostrat  pro  and  carbon  pad)),  the  tank  also  uses  a  boyo  1000F  internal  filter  taken  from  a  running  tank  and  lots  of  stones  with  holes  and  plastic  and  silk  plants  also  from  a  running  tank.  10%  was  the  initial  water  was  also  from  a  running  tank.   It  also  has  some  fish  (Bronze  and  Albino  Cory's,  1  x  4"  Black  Ghost/Feather,  1  x  Rainbow  shark  (EDIT:  removed  the  rainbow  shark  as  it  was  troubling  the  Black  Ghost),  some  Rainbow  fishes,  1  x  3"  Severum.  )  which  were  added  over  this  period.  Feedings  are  minimal  for  now.  There  are  some  more  Bosemans  in  my  other  tank  which  will  be  added  here  gradually.
 
 Q  is,  since  I  used  a  filter,  and  rocks  from  a  running  tank,  is  it  at  all  possible  that  my  tank  is  already  cycled?  Should  I  be  expecting  a  No2  and  Ammonia  spike?
 
 I  usually  top  off  the  evaporated  water  so  total  water  change  in  2  weeks  is  15%.  Have  sadly  lost  a  small  Ramirezi  (0.5")  which  I  believe  was  taken  by  the  Severum  and  was  not  a  WQC  (water  quality  casualty).
 
 
 Cheers...

 Your  new  tank  has  been  jump  started  with  filter,  water,  stuff  from  exsisting  tank.  The  bacteria  in  these  places  seem  to  be  handling  you  bioload,  and  there  should  not  be  a  problem.
 I  don't  think  you  will  have  a  jump  in  either  ammonia  or  nitirtes  as  long  as  you  do  not  add  fish  suddenly.
 Topping  up  evaporated  water  is  not  ehough,  you  have  to  make  water  changes  also.
 The  nitrates  are  end  product  of  ammonia  cycle  and  can  only  be  removed  by  water  changes.
 Your  nitrate  reading  "10-25"  is  too  broad  range,  how  are  you  testing  them.  Nitrates  should  not  go  above  20  ppm.  You  need  to  do  water  changes  to  bring  them  down.

 Thanks  for  your  comments  and  reassurance  Sandeep.  
 
 Yes  I  am  planing  a  20%  change  today.  I  use  the  Tetra  5  in  1  Test  Strips  for  No2,  No3,  Kh,  GH  and  PH,  and  the  Sera  Ammonia/Ammonium  Test  Kit.
 
 The  reason  I  say  10-25  is  because  as  per  colour  chart  the  pink  shade  is  somewhere  in  the  middle.  
 
 I  have  been  adding  2-3  small  fish  every  2-3  days  over  the  last  2  weeks  and  they  arent  full  size  and  not  particularly  messy  fish  so  bio  load  is  controlled.  Currently  the  aquarium  has  5  very  small  (1")  corydoras,  1  x  4"  Severum,  1  x  3.5"  Black  Ghost,  7  x  2"  Rainbow  Fishes  and  1  x  3"  Suckercat.
 
 After  3  days  of  this  load,  the  readings  were  as  above.  Water  change  will  control  the  nitrate  i  think.
 
 The  last  4  Bosemans  are  3.5"  each  in  size  and  were  a  bit  expensive  so  still  in  the  smaller  established  tank,  which  incidentally  has  the  same  water  characteristics.  They  will  go  ionto  the  big  tnk  next  week  if  water  parameters  hold  up.(I  frequently  top  off  the  smaller  aquarium  with  some  of  the  new  aquarium  water  just  to  get  them  used  to  the  water)
 
 Btw,  I  still  have  the  carbon  pad  in  my  2217.  Should  I  chuck  it?  What  implications  will  doing  that  have?
 
 Cheers...

 Carbon  pads  have  a  life,  they  are  good  at  absorbing  impurities  from  water,  but  once  their  life  is  over,  they  are  of  no  use.
 I  don't  have  a  idea  of  life  of  carbon  pad  of  2217,  never  used  carbon  in  my  tanks.  Smile

 Carbon  pad  is  good  to  use  in  a  newly  setup  tank  as  it  removes  excess  nutirnts  and  chemicals  in  the  water  column,  not  sure  about  the  life  of  a  2217  Carbon  Pad,  should  ideally  be  anything  between  7-14  days.  
 
 Once  your  Tank  is  cycled  you  dont  need  to  use  a  carbon  pad.

 Thanks  Seetharaman.  Mine  has  been  running  for  2  weeks  now.  
 
 Does  the  carbon  pad  make  the  water  soft  as  well??  What  will  change  in  the  water  parameters  once  I  stop  using  the  pad?
 
 Btw  Sandeep  I  did  a  20%  water  change  and  tested  again  after  a  couple  of  hours.
 
 No2  is  0  and  No3  is  10  ppm,  Ammonia  is  0,  Gh  is  6  deg,  Kh  is  between  3  deg  but  the  ph  dropped  to  6.8.  Earlier  it  was  7.2.  Hope  this  isnt  too  much  of  an  issue.

 Carbon  pad  will  not  make  the  water  soft.
 The  test  strips  can  be  used  for  broad  indicators  only  they  are  not  very  senstive,  hence  you  cannot  rely  on  reading  going  down  from  7.2  to  6.8.
 As  fishes  live  in  water  the  ph  levels  will  vary,  but  the  changes  will  not  be  too  much.
 I  hope  you  are  not  using  RO  water,  if  you  are  you  need  to  mix  it  with  some  tap  water  as  RO  water  has  no  buffering  and  ph  swings  can  be  voilent.
 A  weekly  change  of  20-25  %  is  enough  to  take  care  of  all  troubles.

 Thanks  for  the  tips  Sandeep.  With  the  big  tank  now  running,  I  am  going  a  little  easy  on  the  RO  now.  Its  20-30%  RO  and  70-80%  Tap  water  now.
 
 I'll  probably  take  out  the  carbon  pad  today  or  tomorrow.
 
 My  new  hood  is  also  almost  done  (Its  a  DIY  using  a  very  new  material,  light  and  strong  and  easily  self  fabricated  in  almost  any  design))  so  you  guys  should  be  seeing  some  pictures  soon.
 
 Cheers...

 Your  tank  is  cycled  once  nitrates  are  present  in  the  tank.
