 hi,  i  am  having  problem  with  growing  cabomba  carolina  .  i  put  them  in  my  tank  around  2  weeks  ago  ,  before  that  they  were  in  my  out  door  pot  .  their  tops  turned  brownish  white  but  grew  with  a  steady  rate  .  but  now  they  have  suddenly  stopped  growing  .  their  tops  have  turned  completely  white   .  this  has  happened  to  me  before  but  i  did  not  have  any  substrate  at  that  so  i  suspected  that  no  substrate  was  the  reason  .  i  know  they  will  soon  start  breaking  off.
 details  
 substrate  :  thin  layer  of  black  soil  ,  3  inch  layer  of  sand
 light:  20W  X  2  CFL(cool  daylight)  15W  X1  CFL  (warm  sunlight)
 fishes  7  guppys  1  betta  3  mollys  and  lots  of  wild  shrimps  .  what  is  its  reason  and  how  can  i  prevent  it

 Maybe  there  is  not  enough  co2  in  the  tank..also  lack  of  nutrients  can  cause  the  leaves  to  lose  their  coloration.
 Do  you  supply  co2??

 All  plants  need  time  to  acclimate  in  a  new  tank.
 I  would  keep  an  eye  out  for  new  shoots  and  leaves.  
 If  they  are  not  sprouting,  then  start  to  worry.
 Cabomba  has  grown  well  in  my  tank  most  of  the  time.  
 But  time  to  time  a  few  shoots  melt  after  being  trimmed.  
 Just  a  thought.
 Thanks,  
 Arin

 There  is  no  co2  supply  .  co2  from  fishes  only.   
 Arin  they  grew  well  for  the  first  week  but  have  now  suddenly  stopped  growing.
 The  tank'  18  gallons  .  it  contains  15-16  gallons  of  water  
 Hard  water?  Have  no  idea  .
 As  i  have  already  mentioned  they  grow  very  well  in  the  outside  pot  of  15  gallons

 They  grow  very  well  outside  because  they  receive  enough  sunlight..
 they  grew  well  for  the  first  week  because  they  had  enough  nutrients  stored  in  them..now  since  they  have  used  up  all  the  nutrients..i  guess  they  are  lacking  nutrients...the  lighting  seems  fine  to  me  though.
 try  introducing  DIY   CO2.

 Ashwin  Mathew.

 Vishu,
 
 There  are  three  pigments  in  plants  which  gives  it  the  coloration  1.  chlorophyll  2.  carotenoides  3.  Anthocyanins
 the  chlorophyll  gives  the  green  coloration  the  carotenoides  gives  the  yellow  coloration  and  anthocyanins  gives  the  reds  and  the  purple  coloration.  Now  the  characteristic  of  chlorophyll  is  that  it  is  very  unstable  and  it  breaks  up  easily  under  high  lighting  and  the  plant  needs  the  nutrients  and  Co2  to  build  it  back  but  if  does  not  happen  the  carotenoides  are  exposed  thats  why  you  see  the  yellow  coloration  this  is  called  cholorosis.  Even  at  this  time  sufficient  nutrients  are  not  given  then  the  carotenoides  also  breaks  up.  Thats  why  you  saw  the  white  coloration.  If  care  is  not  taken  at  this  point  the  plants  start  to  disintegrate  this  is  what  is  called  as  necrosis.        
 
 Cause  for  your  problem
 
 you  have  about  3.5  watts  of  lighting  in  your  aquarium  which  is  on  the  bit  higher  for  a  non  Co2  aquarium.  In  a  planted  aquarium  growth  is  driven  by  3  factors  1.Lighting  2.Co2  3.Ferts.  And  for  success  all  three  should  be  in  balance.  
 
 Since  your  aquarium  does  not  have  pressurized  Co2  system  my  advice  would  be  to  reduce  the  lighting  to  around  50Watts  your  current  total  adds  upto  65  Watts  
 
 Secondly  if  possible  change  the  light  spectrum  6500  kelvin.  I  remember  one  of  your  light  had  a  warm  white  rating  which  is  around  4500  K  and  emits  a  spectrum  which  does  not  overlap  too  much  with  the  photosynthetic  spectrum
 
 also  make  sure  that  you  supplement  this  with  sufficient  nutrients.

 Vishnu,
 As  you  are  not  having  any  CO2  support  at  the  moment,  please  start  the  DIY  CO2  or  start  giving  Glut  Dosing.  
 
 Without  CO2  the  plants  will  not  thrive.
