 Hi  Joyban,
 Thanks  for  the  reply
 
 According  to
 http://fins.actwin.com/aquatic-plants/month.9805/msg00387.html  Fertilon  has  4%  Iron
 
 but  in  your  pervious  posting  you  have  mentioned  that  Fertilon  fron  Vardhaman  Fertilizers  has  13%  Iron.
 
 Am  I  missing  some  thing,  Just  wanted  to  be  sure    Smile
 
 Thanks,
 G.Senthil  Kumar

 Yes  ,  you  are  missing  something...  Very Happy  
 
 FETRILON-COMBI  -I  &  FETRILON-COMBI  -II  are  from  BASF  re  packed  by  Verdhaman  Fertilisers,  Fetrilon  -  13%  is  an  other  product  which  has  only  Iron  EDTA  also  from  BASF  repacked  in  100gms  packets  from  Verdhaman  Fertilisers.
 
 So  Fetrilon  has  only  Iron  while  the  Fertilon  Combo  has  Iron  plus  Mn  Zn  Cu    B  Mo  MgO  &  S
 
 Hope  this  makes  it  clear.
 
 Also  DTPA  Iron  is  available  form  Verdhaman  Fertilisers  but  apperently  they  cannot  be  sold  in  India  so  they  only  sell  it  by  special  request.  DTPA  iron  is  more  stable  than  EDTA.
 
 Regards

 OK  got  it    Smile  
 
 Then,  WRT  PMDD,  for  micros  we  should  go  with  Microsol-B,  if  in  case  we  need  more  Iron  add  Fertilon  -  13%
 
 Right?

 Yes  that's  what  you  can  do.
 
 It  may  not  be  necessary  though.

 Hi  All,
 
 Yesterday  I  got  micronutrient  sol  of  Devidayal  Agro  Chemicals  from  a  friend  who  is  a  micronutrient  dealer  in  Delhi.
 Its  composition  is  Elemental  Zinc-3.0%,  Manganese  0.5  %,  Boron  0.1%,  Nitrogen  in  Ammonical  form  4.0%,  Chelating  agent  &  inert  carrier.  
 I  haven’t  used  it  but  want  to  know  should  I  use  it  or  not  as  it  is  meant  for  use  in  farmland  not  in  aquarium  and  if  yes  how  much.
 
 
 Regards
 Bhaskar

 Bhaskar,
 
 Never  dose  anything  that  contains  Nitrogen  in  Ammonical  form  into  your  tank.
 
 The  micronutrient  mixture  you  have  will  not  do!

 Hi  all
 
 I  have  weighed  the  following  chemicals  used  in  PMDD  Mix  using  50gmsX.01gms  electronic  scale.
 
 I  have  used  a  10ml  plastic  container,  weight  each  chemical  three  times  and  then  taken  a  weighted  average.  
 
 1  teaspoon  standard  is  equal  to  4.928922  ml  &  1  tablespoon  standard  is  equal  to  14.78676  ml
 
 Epsom  Salt  -  MgSO4,  7H20  -  From  Bio  Labs  New  Delhi.
 Microsol  B  -  From  Vardhaman  Fertilizer  
 Fertilon  -  13%  -  From  Vardhaman  Fertilizer  (BASF)
 Boric  Acid  -  Normal  Pharmacy  Grade
 Potassium  Sulphate  -  From  Vardhaman  Fertilizer  (Kemira  GrowHow)
 Potassium  Nitrate  -  From  Vardhaman  Fertilizer  (Kemira  GrowHow)
 
 Epsom  Salt  1tsp  =  4.908  gms  ,  1  TBL  Sp  =  14.935  gms
 Microsol  B  1  tsp  =  3.603  gms  ,  1  TBL  Sp  =  10.965  gms
 Fertilon  13%  1tsp  =  4.267  gms,  1  TBL  Sp  =  12.985  gms
 Boric  Acid  Powder  1  tsp  =  3.151  gms,  1  TBL  Sp  =  9.590  gms
 Potassium  Sulphate  1  tsp  =  6.997  gms,  1  TBL  Sp  =  21.295  gms
 Potassium  Nitrate  1tsp  =  5.906  gms,  1  TBL  Sp  =  17.975  gms
 
 Epsom  Salt    -  Mg=9.70%  &  S=13%
 Microsol  B  -  Fe=5%,  Mn=2.50%,  Zn=1%,  Cu=2.50%,  Mo=0.035%,Bo=2.50%
 Fertilon  13%  -  Fe  =12.70%  ,  Mg  =  .25%
 Boric  Acid  Powder  -  Bo=17.48%
 Potassium  Sulphate  -  K20  =  50%,S=18%,K=41.50%
 Potassium  Nitrate-  NO3  =13.50%,  K2O  =45%,K=37.50%
 
 1ppm  =  1mg  of  solid  in  1000000mg  of  water  or  1mg  in  1  liter  of  water.  
 
 Hope  this  will  help  to  calculate  the  ppm  for  each  element  for  the  use  of  dosing  the  mixture  in  the  aquarium.

I  might  not  be  right  but  this  is  the  propotion  in  which  I  mix  the  PMDD  mixture:
 2  Teaspoons  (~14g)  K2SO4  (potassium  sulfate)
 1  Teaspoon  (~6g)  KNO3  (potassium  nitrate)
 2.5  Tablespoons  (~33g)  MgSO4-7H2O  (fully  hydrated  magnesium  sulfate,  aka  epsom  salts;  omit  if  present  in  trace  element  mix)
 1  Tablespoon  (~9g)  Chelated  Trace  Element  Mix
 (7%  Fe,  1.3%  B,  2%  Mn,  0.06%  Mo,  0.4%  Zn,  0.1%  Cu,  EDTA,  DTPA)
 300  ml  (1.5  cups)  distilled  H2O  
 To  this  I  also  add  one  spoon  of  Boric  acid.
 Venket                

 
 Does  all  the  chemical  to  be  mixed  together  or  micro  /  macro  sol  to  be  used  separately...
 
 I  have  tried  to  mix  all  the  chemicals  in  the  above  said  quantity  but  found  that  one  chemical  (I  think  potassium  nitrate)  is  not  soluble  in  water.
 
 Im  using  potassium  nitrate  &  potassium  sulfate  of  laboratory  grade  not  the  commercial  grade
 
 Pls  clarify  me  on  this  as  it  is  driving  me  crazy…………  Surprised      Shocked    Shocked

 Hello  Bhaskar,
 
 
 All  the  chemicals  are  mixed  together  and  diluted  with  distilled  water.
 
 Kno3  dissolves  easily  in  water.  They  are  a  slightly  crystaline  and  is  a  little  tougher  than  the  other  chemicals  to  mix,  but  ultimately  they  do  dissolve  after  vigerous  stirring.  I  have  used  "Merck"  brand  chemicals.  I  heard  those  are  good  quality  chems.  You  can  try  out  the  regular  Vardhaman  fertilizers  stuff  too.  Thats  what  I  use  these  days  to  dose  at  every  water  change.

 Just  wondering.........
 
 Many  micronutrient  mixes  are  sold  as  "foliars".  I  am  making  a  wild  guess  this  is  becuse  they  are  easily  absorbed  from  the  leaves  and  they  dont  need  to  reach  the  roots.
 
 For  those  looking  around  for  DTPA:  chelators  will  exchange  their  cations  easily  for  others.  That  is  the  reason  why  we  are  using  them  (see  below).  Mixing  equal  molar  concentrations  of  sodium  DTPA  and  ferrous  salts  like  ferrous  chloride  or  ferrous  sulphate  (ferrous  chloride  turns  mushy  as  it  is  so  highly  soluble  in  water  that  it  absorbs  moisture  from  air)  should  give  adequate  levels  of  ferrous  DTPA.  But  DTPA  salts,  like  many  other  lab  reagents,  are  costly  and  dont  come  in  small  amounts.  Maybe  people  could  pool  the  funds  if  they  are  really  interested.
 
 I  also  believe  sulphate  contributes  to  nonremovable  hardness,  while  chloride  contributes  to  salinity.  Comments/  correction  much  appreciated  on  this  aspect.
 
 Deepesh
 
 Actually  plants  naturally  concentrate  potassium.  Even  human  cells  contain  20  times  more  potassium  than  sodium.  Once  plants  concentrate  potassium  it  is  used  as  a  currency  in  their  roots.  It  is  exchanged  for  other  cations.  To  take  in  one  ferrous  ion  the  plant  shells  out  two  potassium  ions  (ferrous  has  two  positive  charges  and  potassium  has  one  and  electrical  neutrality  is  maintained  when  micronutrients  are  taken  up).
