 Old  Leafs  of  my  anubias  nana  are  turning  yellow.

 Tank  details  are  as  follows
 Tank  Size  :-  45g,  36X18x18
 Substrate:-  ADA  Amazonia,  12  lit  +gravel
 Lights-  160  w  ,9  hrs
 Co2:-  Pressurised,  light  green  on  drop  checker
 Filter:-  Eheim  2224
 Fertilizer   Weekly
 K   36  ppm
 N   16  ppm
 P      .3  ppm  weekly
 Fe     .1  ppm
 Fauna  Black  widows,  mollies
 No  Bga,  diatoms  on  plants.
 
 I  perform  60%  water  change  every  week,  filter  cleaned  monthly,  tank  is  3  month  old.

 Hi  Sandeep
 I'm  not  expert  but  we  all  usually  do  30-50%  water  changes.
 Why  do  you  do  60%  ?
 Cheers

 No  particular  reason.  Smile  .
 It  is  easier  for  me
 I  change  100  lit  of  water  every  week,  50  lit  of  RO  water  is  mixed  with  50  lit  of  normal  water.

 Check  the  rhizome  for  rotting.  Check  if  you  have  tied  it  too  tight.

 Ok,  will  do  that.
 I  just  moved  them  to  a  place  in  tank  where  they  might  be  receiving  too  much  light,  can  that  be  a  reason.
 Might  move  them  back  to  their  original  location

 Potassium  deficiency  first  shows  up  in  fast  growing  plants.  
 I  have  Hygrophyla  in  my  tank,  they  seem  to  be  doing  all  right.
 This  problem  is  only  becoming  visible  in  anubias  and  in  crypts  to  some  extent.

 Hi  Sandeep  
 It  is  a  very  beautiful  tank.  Sorry  to  hear  about  your  anubias.
 I  once  had  the  same  problem  with  anubias  that  had  been  a  recent  purchase.
 Had  happened  due  to  the  poor  conditions  faced  by  the  hardy  plant  in  transportation.
 Hv  u  acquired  the  plants  recently?
 Regards
 Kuldip

 They  have  been  with  me  for  6  months  now,  although  they  have  been  through  a  lot.
 Tank  changes,  fluctuating  co2  levels,  algae  attacks,  you  name  it  and  you  have  it.  Smile

 My  source  water  had  very  high  TDS.
 
 http://indianaquariumhobbyist.com/community/modules.php?name=Forums&file=viewtopic&t=30022&highlight=
 
 To  control  this  I  started  mixing  50%  RO  water.
 Now  I  am  not  dosing  Mg,  can  this  be  due  to  Mg.
 Original  Mgwas  75  ppm  it  might  have  come  down  to  30-40ppm.
 Can  this  be  a  problem

 Madan  I  am  assuming  that  Mg  is  30  ppm  I  do  not  have  a  test  kit.
 Does  RO  water  remove  nearly  all  Mg  and  Ca  or  brings  it  down  to  90%  as  it  does  with  Ro  water,  any  idea.
 My  tap  water  has  hardness  of  520  ppm  or  29.07,  now  by  RO  water  use  it  would  have  come  down  to  288  or  approx  16.
 Again  i  am  assuming  that  RO  water  will  have  a  hardness  of  100.  Very Happy  .
 
 As  I  do  not  have  test  kits  I  am  relying  on  plant  health.
 Younger  leaves  of  all  plants  including  anubias  are  not  any  signs  of  damage.
 Hence  i  am  assuming  that  it  is  mobile  nutrients  that  are  becoming  short.
 I  am  dosing  P,  K,  iron,  boron  etc.  The  only  thing  I  am  not  dosing  is  Mg.
 It  is  the  older  leaves  of  anubias  and  crypts  to  some  extent  that  are  showing  signs  of  yellow.
