 Dear  All,
 
 As  per  the  WPG  rule  how  will  you  define  a  Low  /  Medium  and  High  Light  Tank.How  about  having  a  0.6  wpg  Tank  ?  Will  Low  light  really  keep  algae  out  ?
 
 Thanks.
   :)

 IMO,
 
 Low  light:  Anythign  less  than  1.5  watt  per  gallon
 Medium  light:  Anything  between  2  to  2.5  watt  per  gallon
 High  light:  Anthing  above  3  watt  per  gallon.
 
 Low  light  tanks  are  much  easier  to  maintain.  My  current  native  crypt  tank  is  doing  very  well  with  just  36  watts  of  light  for  135  gallon  tank.

 Crypts  will  be  my  first  choice,  you  can  also  add  moss,  anubias,  ferns,  hygrophila  difformis,  ludwiga  ovalis.  These  are  the  plants  that  I  have  grown  without  use  of  Co2  or  high  light.

 IME  the  amount  of  light;   intensity  and  source  depends  solely  on  the  height  of  water  column.
 
 CFL  will  do  for  upto  15  inches  of  water  column  height.  Beyond  this  you  may  need  a  different  source  for  the  lights  that  can  penetrate  deeper.
 
 A  point  source  of  light  will  not  be  good  for  a  small  tank.  A  CFL/PLL  tube  would  be  better  as  you  will  have  an  even  distrubition  of  light.

 I  once  had  an  aquarium  in  the  corner  of  my  room  at  90°  to  a  South  facing  window.  It  had  no  lights  and  a  glass  top.  I  could  grow  most  of  the  plants  available  to  a  hobbyist  then  (25  years  ago  and  those  plants  included  the  cabomba  carolina).  Ambient  light  should  always  be  taken  into  consideration  when  calculating  the  illumination  of  your  aquarium.

 Intensity  is  different  for  the  amount  of  light  .
