 Dear  all
 
 Yesterday  I  tested  the  parameters  for  my  70G  marine  tank.
 Ammonia  had  shot  up  to  0.5ppm.
 The  nitrite  and  nitrate  levels  are  however  at  0ppm.
 
 CONCERNS  :
 1)  Is  it  possible  to  have  ammonia  to  such  levels  with  Nitrites/Nitrates  at  0  ppm?
 
 2)Is  there  something  wrong  with  the  biological  filteration?  
 I  have  about  50Kgs  of  live  rock  and  the  ammonia  levels  are  up  for  the  first  time  in  last  6  months.  I  have  an  external  canister  running  with  sponges  and  GAC  (carbon).
 
 3)  I  did  a  partial  WC  (20  %)  last  night.  When  do  I  check  the  ammonia  levels  again  to  be  sure?
 
 PS  all  the  livestock  is  active  and  shows  absolutely  no  signs  of  stress/discomfort.

 I  am  also  only  a  beginner  and  so  whatever  i  convey  must  be  rechecked  with  experts.
 
 a)  The  spike  in  ammonia  maybe  due  to  some  changes  in  the  tank's  live  rock  that  yu  may  have  moved,  or  due  to  some  activities  of  the  invertibrates  that  may  be  bleaching.  If  problem  is  due  to  live  rock  then  it  may  get  corrected  in  due  course,  else  please  look  for  the  culprit.
 
 b)  It  may  not  be  advisible  to  tinker  around  with  the  filtration  media  now,  it  may  only  lead  to  further  spikes  in  ammonia,  NO2  etc.
 
 c)  Since  you  have  done  the  water  change  i  guess  you  can  wait  for  a  couple  of  days  more  and  repeat  the  ammonia  and  NO2  tests.  I  have  noted  that  after  a  couple  of  days  the  NO2  level  picks  up  and  then  reduces.  When  i  have  seen  such  problems,  i  have  also  only  done  water  changes  and  not  disturbed  the  media  and  have  not  had  any  casualties.  (  P.S.  -  I  do  not  have  any  anemones  or  corals  in  my  tank)
 
 I  guess  you  should  not  have  a  cause  for  concern  but  then  watch  the  fishes  for  a  couple  of  days  more  and  then  repeat  the  tests.

 IF  you  disturb  the  sand  bed  it  may  cause  an  smmonia  spike.  Also  make  sure  none  of  your  fish  have  died.  Sometimes  if  the  test  is  old  it  may  give  you  wrong  readings.  Just  a  few  causes.

 OK
 So  far  no  casualties.  All  fish  are  fine  and  I  gave  them  a  meal  much  less  in  quantity(only  after  24  hrs  post  water  change).  Assured  no  left  overs  as  all  fond  was  consumed  within  seconds.
   
 Given  that  there  is  an  ammonia  hike.  Say  for  XYZ  reasons.  A  WC  done.  24  hours  have  already  passed.
 
 When  to  conduct  the  next  ammonia  test?
 
 Need  to  be  sure  of  the  conditions  that  would  now  prevail.  I  usually  undertake  the  test  in  every  10  days.
 
 Should  I  have  taken  an  immediate  test  after  water  change  or  should  I  wait  for  a  couple  of  days?

 Oops  forgot  to  mention.
 The  test  Kit  is  new.  Using  API  master  test  kit.
 
 I  did  do  some  internal  movement  of  rocks  to  adjust  the  pump  attached  to  the  skimmer.  So  this  may  the  reason.
 The  earlier  test  result  for  ammonia  was  0ppm.
 The  one  undertaken  20  days  back  was  .25ppm
 The  one  taken  30  days  back  was  0ppm.
 
 The  skimmer  has  been  running  contineously  since  the  water  change  and  so  is  the  canister  filter  (it  runs  24x7)
 
 Do  i  need  to  add  more  for  bio  filteration.  for  eg   say  a  top  filter  with  bio  media??

 I  would  say  do  immediate  water  change  to  bring  down  the  ammonia.  May  be  about  20  to  30%  every  day  to  bring  the  ammonia  to  zero.  Your  beneficial  bacteria  dont  live  in  the  water  column  so  it  wont  hurt  their  population.  
 
 I  always  like  to  conduct  the  test  at  noon  just  before  my  lights  come  also  it  wont  hurt  to  test  the  water  every  day  till  you  bring  the  ammonia  down.  
 
 Also  if  you  have  live  rock  and  skimmer,  why  are  you  using  canister  filter?

 Dear  Gremlin
 
 Thanks,  Water  Change  done.  Would  repeat  the  same  tomorrow  and  then  check  it  at  noon.
 
 
 My  tank  dimensions  are  42"X21"x24"
 
 Am  using  about  36  Kgs  live  rocks  along  with  15  Kgs  dead  base  rocks.
 Have  a  SA2014  protein  skimmer.
 The  canister  was  for  the  earlier  freshwater  set  up  but  hardly  used  as  I  shifted  to  Marine  just  months  after  procuring  the  filter.  I  used  this  as  it  was  the  only  filter  with  me  (  the  proteing  skimmer  was  procured  2  months  post  the  setup).  I'm  currently  using  this  with  CAG  and  it  runs  24x7  (  on  inverter),  even  when  the  skimmer  is  off  during  power  cuts.  
 Regular  cleaning  undertaken.  Scanty  Livestok  gave  me  no  reasons  to  worry  until  this  week  when  I  added  3  fishes.
 
 Should  I  disconnect  the  canister?
 Is  there  any  hazard  in  having  this  canister  running?

 Oh  ok,  if  it  works  for  you  then  its  good.  Most  of  the  marine  setups  dont  include  canister  filters  because  the  bacteria  and  pods  grow  on  the  live  rock.  The  canister  filters  have  to  be  cleaned  every  so  often  or  it  will  be  a  nitrate  factory.  
 Protine  skimmer  is  your  mechanical  filteration  and  live  rock  is  your  biological  filteration,  these  two  does  what  your  canister  filter  will  do.

 HI  Gremlin
 
 Tested  the  water  yesterday.
 Ammonia:   0  ppm
 Nitrite  :   0ppm
 Nitrate  :  5  ppm
 
 All  livestock  active  and  feeding  normally.  
 Have  reduced  the  food  quantity  marginally.
 
 It  was  a  stress  relief  for  me  more  than  that  for  the  fishes   Cheer  
 
 Just  one  more  advice  needed.  I  have  two  powerheads  on  opp  sides  for  water  circulation.  Sometimes  the  loose  algae  floats  in  the  current  created  and  are  visible.  This  increased  soon  after  introduction  of  a  sailfin  tang  which  grazes  and  looses  the  algae  on  bed  and  on  rocks.
 
 How  do  I  remove  this   small  floating  algae  patches.  The  canister  is  not  able  to  suck  all  of  them  and  maximum  keep  on  rotating  with  the  flow  till  the  time  they  hit  a  rock  and  settle  down  just  to  be  disturbed  again  and  float.

 Sailfin  tangs  are  large  fish.  they  can  grow  up  to  15  inches.  You  will  have  problems  keeping  it  in  a  tank  which  is  less  than  4  feet  and  150  gallons  in  the  long  run.

 Hi  asak
 
 This  wasn't  the  first  choice  to  have  a  sailfin  tang.  The  marine  venture  was  fairly  new  for  me.  Now  feel  totally  involved.  So  much  so  that  we  (i  &  my  wife)  are  planning  a  6-7  ft  tank  for  the  living  room.  Nothing  is  concrete  as  of  today  but  looks  like  a  possibility  before  the  tang  grows  a  inch  in  size.
 Will  keep  you  buddies  posted.
 
 Anyways  any  suggestion  for  my  above  question?

 what  do  you  mean  by  floating  algae?  Algae  usually  forms  on  the  glass,  rock  or  substrate.  Is  is  excess  hair  algae  coming  off  the  rocks?

 Hi,  
 
 I  know  the  Ammonia  spike  issue  is  resolved  in  this  thread.  However  let  me  share  my  experience  on  Ammonia  spike  with  my  freshwater  tank.  
 
 In  my  15  your  of  fish  keeping  experience,  Ammonia  spike  occoured  once  and  unfortunatly  on  a  weekend  while  nobody  was  at  home.  The  tank  was  fully  cycled  18  month  old  planted  setup.  
 I  live  in  the  UK  and  every  Friday  I  feed  my  fish  with  live  blood  worms  and  daphenias.  on  this  particular  instance  I  bought  the  live  worms  from  a  different  store  and   changed  my  plant  supplement  to  a  different  brand  (the  new  one  is  RedSea).  as  usual  i  fed  my  fish  on  friday  lunch  time,  I  did  a  10%  WC  (it's  the  weekly  one)  and  went  out  for  a  holiday.  When  I  returned  on  Sunday  evening  the  disaster  was  just  waiting  for  me.  I  found  6  fishes  were  dead  (most  of  them  are  neon  tetras).  I  did  a  water  test  and  found  that  Ammonia  was  very  high,  so  did  a  80%  WC  just  to  bring  down  the  ammonia.  and  continued  to  do  20%  WC  every  day  for  a  week.  
 
 So  the  possible  reason  could  be  different  live  worms  supplier  or  the  plant  supplement  from  RedSea.  one  of  them  disturbed  my  biological  filter.  I  stopped  using  that  Red  Sea  plant  supplement  and  went  back  to  JBL  (a  german  made).  
 
 You  can  find  my  detail  article  on  New  Tank  Syndrome  &  Aquarium  (Nitrogen)  Cycling  here

 Goodluck

 You  should  try  attaching  a  sponge  filter  to  one  of  your  power  heads  and  run  it  till  you  see  that  the  algae  has  cleared.  Remove  the  sponge  filter  as  soon  as  you  see  that  it  has  cleared.  
 
 Not  an  expert  but  i  think  every  time  you  add  livestock  to  your  tank,  it  goes  through  a  mini  cycle.That  is  the  reason  we  are  advised  not  to  put  too  many  fish  in  at  the  same  time.  The  3  fish  that  you  added  probably  caused  that  spike  in  ammonia.

 Change  in  food  brand/  live  food  is  not  the  issue.  NOt  started  feeding  Live  food  yet.

 Its  algae  scrapped  off  the  rocks  and  picked  up  from  the  bed  by  the  fishes.  These  bits  float  with  the  current  generated  by  powerheads.  Other  fishes  try  to  actch  them  nad  then  spit  back  causing  it  to  further  break  into  finer  bits  rotating  round  the  tank.  It  settles  after  some  mintues  but  the  fishes  dig  in  more.

 I  had  been  waiting  to  add  fishes  for  past  3  months.  At  my  area  it  is  rarely  available.  When  this  stock  arrived  ,  I  became  a  abit  greedy  and  hence  added  this  to  an  almost  empty  tank.
