 Hello,
 
 I  have  a  6ft*21inch*21inch  tank,fully  planted  about  3  months  old  now.The  anubias  were  all  growing  fine  (  around  30  in  number),now  the  rhizome  seems  to  be  rotting.The  rhizome  is  tied  to  a  drift  wood  and  is  nowhere  buried  in  the  substrate.
 
 First,  the  leaves  detach  themselves  and  on  inspection  i  see  the  rhizome  would  be  milk  white  in  colour  like  some  fungus  on  it.  The  problem  is  not  ristricted  to  one  type,i  mean  i  have  it  on  almost  all,  like,  Anubias,  Nana,Petite,minima,  coffefolia  and  bateri.
 
 being  some  where  aound  500  ltrs,  i  dose  around  1.5  teaspoons  of  kno3,.5  teaspoons  of  kh2po4,  and  balace  K(ferka)  on  alternative  days  and  trace  elements  on  alternative  days  again,with  50%  water  change  being  followed  religiously.
 
 Lighting  is  around  1  watt/Litre(  around  4  watts/gallon  )  .
 pressureized  co2,5b/sec,
 
 I  have  tried  cutting  the  rotten  part  and  then  tying  it  back,but  its  back  there  again,
 
 Please  help!!

 i  had  the  same  problem  initially  
 
 realised  it  was  because  i  was  tying  the  thread  too  tightly  around  the  rhizome  hence  causing  the  rhizome  to  be  cut  and  eventually  rotting  
 
 ever  since  i  have  been  loosely  tying  the  anubias  and  the  roots  eventually  attach  themselves  to  the  driftwood  and  all  my  anubias  are  growing  healthily  these  days

 Hello  Scarlet,
 
 The  anubias  are  not  tied  tightly,i  can  move  the  anubias  rhizome  freely.  I  happens  to  even  those  anubias  which  are  not  tied.

 Ph-6.4
 Gh-3
 nitrites-0
 Amonia-0.
 
 
 I  have  a  feeling  that,  whatever  it  is  is  spreading  to  different  anubias,cut  3  rhizomes  today,yester  it  was  1  ,  so  from  the  past  3  weeks  i  have  cut  almost  14-15  rhizomes.Lost  3-4  completely.
 
 Please  help.

 too  much  KH2PO4  and  KNO3?   I  used  Chuck  gadd's  calculator  for  my  tank  which  6  feet  ,24  inches,  24  inches  L,B,H
 
 According  to  him  1/4  tsp  of  KNO3  and  KH2PO4  is  what  i  should  dose...
 
 Have  got  good  growth  and  almost  no  algae..  anubias  is  also  doing  well  now  that  i've  moved  it  to  a  lower  light  area..
 
 So  now  come  to  think  of  it!  maybe  too  much  light?

 Hello  Gautam,
 
 From  where  did  you  get  this  ratio???  i  think  you  have  it  wrong.Kno3  should  be  atleast  10ppm  for  your  tank  size,which  is  around  1.34  teaspoons.
 
 I  might  be  wrong.Just  my  2  cents.

 Cut  and  paste  from  Barreport:
 
 Using  an  "estimative  index"  the  accuracy  can  be  as  follows  for  teaspoons  and  liquids  for  the  traces,  note,  further  accuracy  can  be  achieved  by  diluting  grams  of  each  of  these  nutrients  into  DI  water  and  adding  mls  of  a  concentrated  liquid  into  their  tanks  in  place  of  dry  powder,  but  thios  does  not  gain  the  user  much  in  terms  of  plant  health  and  growth,  which  is  the  main  reason  to  help  improve  a  routine:  
 
 (+  or  -)  5ppm  of  CO2  is  fine  in  a  20-30ppm  range.
 (+  or  -)  1ppm  or  so  of  NO3  is  pretty  reasonable.
 (+  or  -)  2ppm  of  K+  is  pretty  reasonable.
 (+  or  -)  0.2ppm  of  PO4  is  pretty  reasonable  (?)
 (+  or  -)  0.1ppm  of  Fe  is  reasonable  (?)  
 
 CO2  range  25-35ppm
 NO3  range  5-30ppm
 K+  range  10-30ppm
 PO4  range  1.0-3.0  ppm
 Fe  0.2-0.5ppm  or  higher  (?)  
 GH  range  3  degrees  ~  50ppm  or  higher

 I  used  Chuck  Gadd's  Calculator..  everyone  seemed  to  recommend  it...  But  i  will  recheck.  Thanks  for  pointing  it  out.
 
 Just  started  with  KNO3,  so  will  try  increasing  it  gradually  and  see  if  there's  any  difference

 Your  tank  fits  into  this  criteria  i  guess,  maybe  slightly  bigger.  so  the  doses  would  be:
 
 
 100  -  125  Gallon  Aquarium
 
 +/-  1  1/2  tsp  KN03  3x  a  week
 +/-  ½  tsp  KH2P04  3x  a  week
 +/-  ½  tsp  (30ml)  Trace  Elements  3x  a  week
 50%  weekly  water  change.
 
 how  did  you  get  5  teaspoons???

 Dear  Friend,
 I  have  grown  anubias  for  the  past  6  yeaars  or  so  and  have  noticed  this  same  problem  recently  in  one  of  my  new  tanks  where  i  used  amazonia.  the  tank  somewhat  had  a  brownish  appearance  and  the  leaves  of  some  plants  showed  signs  of  distress  with  a  substrate  kind  of  growth  on  the  leaves  maybe  a  brown  algae.  This  feature  was  noticed  after  the  anubias  had  rotted  away.
 pls  also  let  me  know  the  cause  of  the  problem  as  you  pinpoint  it.
 regards
 kuldip
