 Hi  all
 Just  wanted  to  report  that  glu  does  kill  snails.
 My  50  g  planted  angelfish  tank  had  an  bad  case  of  algae  and  snails.
 Due  to  my  resetting  &  uprooting  of  plants  a  lot  of  substrate  was  disturbed  and  i  had  a  bad  attack  of  algae.
 snails  has  always  been  a  problem  in  this  tank.
 To  take  out  algae  I  dosed  5  ml  of  25%  glu  (  this  is  a  very  high  dose),  also  I  shut  off  all  lights.  The  tank  reamined  in  dark  for  three  days.
 On  day  4  when  lights  were  put  on,  all  the  algae  had  gone.  I  was  very  happy  but  did  not  notice  that  snails  had  also  gone  Very Happy  ,  but  they  were  gone  Thumbs Up  
 The  procedure  I  followed  is  as  below:
 Vaccum  the  gravel,  change  some  water.  Shut  of  lights  and  dosed  5  ml  of  concerntrated  glu  in  my  50g  tank.  The  specs  are  50  g  tanks,  planted  with  vals,  e  tenneleus,  glosso,  h  cuba,  echinidorus,  cabomba.
 The  results  were
 Flora:
 Algae-  zapped,  zero  gone  Thumbs Up   Thumbs Up  
 Snails-  zapped  zero  gone  Thumbs Up   Thumbs Up   Thumbs Up   Thumbs Up   Thumbs Up  
 vals-  melted  but  still  holding
 tenneleus-  they  were  planted  just  15  days  back,  leaves  of  some  have  died,  don't  know  if  this  is  effect  of  glu  or  not
 glosso-  no  effect
 H  cuba-  no  effect
 
 Fauna
 
 Angels-  No  effect,  in  fact  one  of  my  black  angles  had  fungus  infection  and  an  infected  eye,  she  is  fully  healed.  antibacterial  effect  of  glu.  not  sure.
 Guppies:  No  effect.
 
 This  was  an  unintended  side  effect  of  glu  but  is  sure  a  very  welcome  one.
 I  have  not  come  across  an  effective  remover  of  snails  withour  proving  disastorous  to  fish  or  plants.
 Please  read  more  about  glu  before  attempting  it.
 Vals,  moss,  anarchias  are  damaged,  I  do  not  have  information  on  other  plants.
 Shrimps,  invertibrates  take  a  hit.
 Please  post  if  any  of  you  have  similar  effects.

 Sandeep,
   The  dosage  was  the  key  here.  Also  so  was  lights  being  shut  off.  Congratts  for  getting  rid  of  snails  and  of-course  alage.  But  even  lower  conc  would  have  killed  snails  and  would  have  not  hurt  delicate  beauties.  But  not  sure  about  alge  eradication.
 
   Note  that  if  you  have  vals,  e  tenneleus,  glosso,  h  cuba,   cabomba.  Then  do  a  water  change  immediately.  would  recommend  50%,  followed  by  a  progressively  10-20%  change  daily   for  a  week  to  get  rid  of  GD.  
 
 And  then  you  might  also  wanna  turn  lights  progressively  on  to  reach  its  max  intensity.  This  way  the  conc  of  GD  would  be  reduced  to  nil,  And  decicate  beauties  would  not  be  too  affected.  
 
 I  recall  this  proccedure  in  some  fourm  so  as  to  minimise  the  effect  of  GD  on  Valls  and  other  plants.  They  mentioned  that  progressive  light  intensity  increase  would  help  valls  to  recover  from  GD  dosage   but  i  do  not  recall  the  link,  Would  post  the  link  if  i  come  across  it  again.

 Low  doses  of  glu  do  not  seem  to  have  any  effect  on  snails.
 I  have  used  glu  before  in  this  tank,  vals  had  taken  a  hit  but  snails  were  still  there.  
 That  is  why  in  one  of  the  queries  by  Nauzur  I  had  answered  that  glu  does  not  seem  to  have  any  effect  on  snails.
 Does  e  tenneleus  have  a  issue  with  glu,  glosso  &  h  cuba  are  unaffected.
 There  must  be  something  different  with  vals  &  tenneleus  to  have  this  effect.
 BTw  there  is  no  effect  on  nitrifying  bacteria,  or  beacuse  of  planted  tank  the  effect  is  not  visible.

 Hi  Sandeep,
   Yep!!!  Even  i  have  seen  E  tenneleus  being  burnt  with  GD  but  they  were  effected  gradually  on  a  continual  dosage.
 
 Just  another  query,  Did  you  try  GD  with  low  dosages  when  lights  were  off  to  kill  snails????  May  be  if  you  have  more  snails  to  experiment  with,  can  you  try  this  exp  also  out.
 
 I  have  dosed  GD  in  a  non  planted  tank  for  eradicating  small  worms  and  Green  water,  And  have  not  seen  a  Ammonia  spike.  I  suppose  i  mentioned  about  it  in  the  other  artical  that  GD  has  no  effect  on  bacteria  when  dosed  in  smaller  PPM's.  In  fact  Bacteria  can  get  used  to  GD  and  will  thrive.

 HI  Nauzer,
   The  chemical  name  by  itslef  is  Gluter-aldehyde.  Its  a  Hydrocarbon  and  belongs  to  Aldehyde  catagory.  The  molecular  equation  is  C5H8O2.
 
 For  a  chemical  bonding  you  can  look  at
 
   http://www.ilpi.com/msds/ref/ketone.html
 
 I  suppose  this  is  what  you  were  looking  for....

 Nauzur
 It  is  known  by  same  name,  and  is  available  in  strengths  of  25%  &  50%.
 25%  strength  is  what  I  am  using.
 Please  take  care,  it  is  an  extremely  toxic  chemical,  even  fumes  are  dangerous.  Open  bottle  &  use  it  in  open  places  only.  I  use  gloves  when  handling  it.
 Flourish  excel  uses  it  in  srength  of  2.5%  and  for  co2  fertilizaton  purpose  it  is  used  at  1.5%.  at  25  %  it  is  highly  dangerous.
 also  keep  it  out  of  light.

 ya  this  is  what  I  was  looking  for  -  thanks  a  lot  guys  now  I  start  my  hunt  for  GD  and  then  hunt  down  the  snails  Guns
 only  problem  though  is  the  light  -  the  tank  is  on  the  outside  exposed  to  semi-sunlight  conditions  and  that  is  what  is  bothering  me.  let  me  see  if  I  could  do  the  trick  in  the  night  or  just  stick  a  news  paper  of  something  to  shade  it.

 Glutaraldehyde  is  the  common  chemical  name  everywhere  because  that  is  what  the  medics  call  it  much  to  the  chagrin  of  chemists  who  want  it  to  be  called  by  some  really  tough  name.
 
 See  -  formaldehyde,  glutaraldehyde  -  brothers!!
 
 I'll  see  if  it  is  available  in  a  usable  form  at  the  chemists.  I  dont  know  if  the  medical  glutaraldehyde  has  some  additives  to  stabilize  it.  Will  check  out  today.
