 Nauzur
 GD  has  no  effect  on  snails.  They  are  multipling  in  my  tank  like  "snails"   ROFL  
 The  dose  which  nuked  my  algae  has  no  effect  on  them.  I  have  not  tried  higher  doses

 Hi  Sandeep,
   But  when  are  you  adding  Gd  to  your  tank.  Note  that  GD  should  be  dosed  when  lights  go  off.
 If  you  add  GD  during  lights  on,  Their  effect  will  be  minimal  as  they  can  break  up  into  components  that  plants  can  take  in.

 Maybe  that  I  am  off  topic  now.
 
 But  if  you  are  dosing  enough  glutaraldehyde  to  knock  out  your  algae  and  your  bloodworms  and  your  moss...  What  happens  to  the  bacteria,  the  ones  that  you  want  to  be  around?  You  know,  nitrobacter  and  stuff.
 
 Aquascapes,  I  would  guess  it  will  work  on  fish  louse  and  anchor  worms  too  since  it  is  a  cousin  of  formaldehyde  which  we  all  know  as  formalin.
 
 Where  do  you  guys  get  your  glutaraldehyde?  At  my  job  we  use  it  regularly  as  Cidex  (registered  trademark  of  Johnson  and  Johnson)  as  a  2%  solution  which  is  a  powerful  disinfectant  tackling  viruses,  bacteria,  fungi,  protozoans  and  almost  all  spores.  The  concentration  is  the  key  though.

 Deepesh,
   Seachem  claims  that  Excel  is  safe  on  Aqua  bacteria.  Which  has  main  ingreadients  of  a  derivative  of  Gluteraldehyde.  Hence  i  feel  GD  should  still  be  safe  and  should  not  kill  aqua  bacteria.
 
 At  least  i  have  seen  no  impacts  of  Ammonia  Nitrate  Nitrite  reading  changes  after  dosing  GD  as  specified.

 Hi  Sharath,
   Look  at  the  Pro's  and  Con's  before  using  this  chemical.
 
 if  you  are  ok  with  using  it  then  u  can  fetch  a  bottle  from  ASK.  Call  up  trevor  and  find  out  more  details.
 You  can  also  get  it  from  Vasa  Scientific  at  Avenue  Rd  at  the  end  of  the  road  on  the  Mysore  bank  side.
 
 Also  this  is  available  at  labratory  traders  on  Hosur  rd  near  christ  college

 Hi  raghu,
 
 Could  you  tell  me  more  about  Pro's  and  Con's.  As  i  have  not  faced  this  problem  before  so  i  have  no  idea  about  this..  Looking  for  your  reply...
 
 Thanks

 Seachem  claims.  
 
 But  does  anyone  really  know?  It  is  after  all  a  generally  acting  toxin.  Thats  why  we  use  it  as  a  disinfectant.  I  mean  it  is  indiscriminate  and  will  kill  all  the  microbes  we  encounter  and  that  is  what  we  want.  We  as  in  hospitalwalas.
 
 In  a  planted  tank  you  would  not  be  reaching  anywhere  near  the  dosing  used  as  disinfectants,  but  if  your  concentration  is  high  enough  to  kill  algae  then  it  would  in  all  probability  affect  bacteria  too.  In  addition  concentrations  enough  to  kill  higher  animals  like  leeches  and  bloodworms  should  kill  most  unicellular  organisms  barring  perhaps  spores.
 
 You  will  find  lots  of  material  on  the  net.  This  is  just  one  link  http://www.blackwell-synergy.com/links/doi/10.1111/j.1532-950X.2004.04086.x/abs/  .  
 
 Deepesh
 
 That  is  an  abstract  of  a  research  paper.  In  medical  jargon  we  dont  count  bacteria  as  such,  we  count  their  colony  forming  units  -  CFUs.  The  explanation  is  that  when  we  stain  a  'raw'  slide  we  see  ALL  the  bacteria  including  nonviable  and  dead  ones.  Staining  does  not  selective  show  the  live  bacteria  -  the  ones  that  we  are  interested  in.  To  get  the  live  bacteria  we  dilute  them  with  sterile  solutions  and  then  culture  them  on  solid  media.  When  diluting  the  individual  bacteria  get  separated  from  each  other.  Subsequent  culture  on  a  solid  media  allows  each  separate  bacteria  to  divide  and  grow  into  small  colonies  about  0.5  -  2mm  size  easily  visible  to  the  naked  eye.  Each  colony  represents  clones  of  a  single  bacteria.  So  we  do  a  colony  count  for  that  is  the  easy  way.
 
 Err..  sorry  for  the  long  rant  but  I  just  wanted  to  show  that  this  is  'simple'  science  and  science  couldn't  be  more  elegant  than  this.

 Buddy,
   Look  at  this  mail  thread  and  look  at  if  you  have  any  Floura  Funa  mentioned  here  if  so  do  not  dose  GD.  if  you  do  not  have  any  of  these  then  dose  it  @  by  mixing  25%  GD  in  a  liter  of  water  and  add  10ml  of  it  into  your  water  coulmn.
 
 Deepesh,
   Had  the  benifitial  bacteria  colony  been  dead,  I  suppose  water  would  have  bloomed  isint  it,
 
 Also  note  that  Seachem  would  have  not  claimed  that  this  is  safe  for  a  planted  tank,  Cause  that  would  have  ment  an  increase  in  NH3,  No2  or  No3   readings.  Though  Seachem  uses  a  polymer  of  GD  it  is  as  Dangerous  as  GD  itslef.
 
 Note  that  many  of  us  who  have  been  using  GD  have  not  seen  a  known  mortality  due  to  Ammonia  spikes  to  my  knowledge.  May  be  i  might  be  wrong,  At  least  i  have  not  seen  it,  As  i  use  to  regularly  monitor  the  readings  by  TK's.
 
 Just  curious  to  know  what  bacteria's  get  killed  by  GD.

 Very  interestin  topic  indeed!
 Only  putoff  though  is  that  we  succeded  in  confusing  Sarath  more  than  helping  him  Â Smile  
 Sarath,
 I  would  not  advise  you  to  use  GD  if  you  are  a  beginner  and  are  doing  it  without  help  of  experts  -  you  could  rather  identify  what  exactly  you  are  fighting  with  and  then  spicifically  fight  the  battle  with  the  right  weapon  rather  than  using  a  weapon  for  mass-destruction.
 @Raghu,
 I  guess  logically  speaking  Deepesh  has  a  point.  It  is  really  interesting  that  such  a  harsh  dis-infectant  does  not  harm  nitirfying  bacteria.

 Nauzer,  
 
      Check  this  link  out
 
 http://www.bioline.org.br/abstract?id=ej06054&lang=en
 
 So  Bacteria  can  get  accimilised  to  GD  if  dosed  at  less  than  80  -  180  Ppm  and  can  never  kill  them.
 
 On  the  other  hand  due  to  the  GD  dosgaes  that  harden  the  skin  of  insects  and  prevent  them  from  respirating  from  skin  the  insects  such  as  leetch,  worms  and  others  die  due  to  suffocation.
 
 Also  note  that  GD  when

 WOW  that  is  really  interesting  to  note  -  Raghu  you  get  a  bonus  for  sharing  the  info.   Clapping  maybe  I  will  have  to  try  it  out  myself  and  see  how  good  it  is  at  eleminating  snails.

 I  am  not  quite  sure  if  Sharath  has  "Leeches  in  the  tank".  He  had  spoken  to  me  and  said  that   he  will  upload  a  pic  of  the  critters  soon.
