 Hi,
 I've  read  that  Seachem  Excel  uses  Glutaraldehyde  as  a  CO2  source.  Glutaraldehyde  is  metabolised  by  microbes  and  under  aerobic  condition  produces  CO2  as  end  product.  In  addition  to  source  of  carbon  glutaraldehyde  is  also  an  algaecide  and  also  acts  upon  microbes.
 
 The  following  links  may  be  useful  :
 http://www.infectioncontroltoday.com/pdf/UC-20901.pdf
 http://www.glerl.noaa.gov/pubs/fulltext/2005/20050003.pdf
 
 Can  anybody  throw  more  light  on  this?  And  what  is  the  concentration  of  glutaraldehyde  in  Seachem  Excel?  
 
 Any  input?

 Where  have  you  read  that  Seachem  Excel  uses  Glutaraldehyde  as  a  CO2  source?
 
 Can  you  give  me  a  link  please.  It  would  be  interesting  as  Seachem  do  not  divulge  any  information.  They  are  a  fan  of  glutamate  as  a  chealting  agent  as  opposed  to  EDTA  which  preferred,  so  using  Glutraldehyde  as  a  source  of  CO2  is  quiet  possible.
 
 If  it  needs  microbes  to  release  the  CO2,  then  it  may  actually  not  be  the  ingredient  in  Excel,  as  Excel  can  be  used  from  day  1  of  startup.
 
 The  active  ingredient  in  Excel  could  be  a  derivative  of  Glutraldehyde,  and  not  Glutraldehyde  itself.

 Hi  madan,
 I've  read  it  in  plantgeeks    forums.  it  seems  that  plants  can  use  glutaraldehyde  directly  or  an  intermediate  of  it  as  carbon  source  instead  of  converving  it  to  Co2.  here  is  the  link:

 Hi  Madan,
 
 Please  see  this  link.  http://www.iaglr.org/scipolicy/ais/ais_iaglr02.pdf  page  12/22.  Will  be  of  interest  to  tankers  chief  engineers  !  Very Happy  
 
 Gluteraldehyde  seems  to  be  a  biocide.  I  wonder  what  effect  it  will  have  on  aquarium  microbes.

 Woah!  Before  anyone  starts  playing  around  with  it,  please  note  that  glutaraldehyde  is  listed  as  a  toxic  chemical.
 
 http://ptcl.chem.ox.ac.uk/MSDS/GL/glutaric_dialdehyde.html
 
 Seachem  probably  uses  it  at  concentrations  below  5ppm,  when  it  is  no  longer  considered  toxic  to  organisms.

 Absolutely  dangerous.  We  used  to  have  a  preparation  called  Cidex  to  sterilize  surgical  instruments  that  could  not  be  put  in  an  autoclave.  It  has  been  withdrawn  from  the  market.  Even  more  dangerous  in  a  domestic  environment  where  kids  or  pets  could  get  at  it.

 but  seachem  uses  it  commercially.  and  seachem  excel  is  used  extensively  abroad.  so  if  we  can  know  the  actual  concentration  of  glutaraldehyde  in  seachem  excel  -  we  may  give  it  a  try.  
 If  anybody  can  send  me  10  -15  ml  of  seachem  excel  I  may  try  to  find  out  actual  concentration  of  glutaraldehyde  in  it.

 Arup,  I  found  this  intersting  chat  on  Seachem  support  site:They  claim  to  use  Polycycloglutaracetal  -  an  isomeric  form  of  glutaraldehyde...  which  is  less  reactive  than  glutaraldehyde.

 thanks  gopi  for  the  link.
 
 EDIT  1  :
 just  got  this  link
 http://tropicalresources.net/phpBB2/viewtopic.php?t=11482&sid=a8661b62da1591686f4ddfeb830f2e84
 
 EDIT  2  ;
   Read  this  one  too
 http://en.wikipedia.org/wiki/Glutaraldehyde
 
 Polycycloglutaracetal  is  a  synonym  for  Glutaraldehyde  Chuckle

 Like  I  said  before,  Seachem  probably  uses  it  in  concentrations  below  5  ppm.  I  seriously  doubt  you'll  be  able  to  get  glutaraldehyde  in  concentrations  anywhere  near  as  diluted.

 glutaraldehyde  is  available  in  25%  and  50%  soln.  you  can  always  dilute  with  water.  just  take  some  precaution  when  handling  the  chemical.  handle  it  under  the  kithchen  chimny  and  wear  eyeglasses  and  a  pair  of  latex  gloves.  and  if  you  cover  your  nostril  and  mouth  wet  towel  then  you  can  handle  it  outside  the  house  e,g  in  your  backyard.
