"MG  will  not  help  increase  your  CA  levels.  it  will  only  make  the  CA  available  to  your  corals  adn  coralline.  "
 
 You  got  this  wrong.
 Without  correct  level  of  Mg  i  doubt  you  can  Alk  to  9  dKH  and  Ca  to  400  ppm.  I  think  its  called  Mg  poisoning.  Mg  forms  a  complex  around  Ca  ion  which  stops  it  from  combining  with  carbonate  hence  you  can  reach  these  levels  of  saturation  without  the  calcium  precip  .
 
 
 Its  very  easy  to  correct  the  imbalance  once  the  levels  are  known                

 
 
 Rahul,
 Yes.  you  are  correct  in  the  chemical  analysis.  however,  just  adding  MG  will  not  up  your  CA  levels  (that  is  what  our  friend  was  mentioning).
 the  combining  thing  is  exactly  what  i  said.  only  when  Mg  is  in  correct  propotion  (3x  times  CA)  will  it  allow  the  ca  and  carbonate  to  be  available.
 
 but  just  dosing  without  testing  is  risky.  
 
 btw  a  bit  tangent  here,  what  will  you  say  to  this  (my  tank  actually)
 MG  1270
 Alk  -  5
 CA  300-320  (but  amazing  coralline  growth)
 
 no  amount  of  CA  dosing  (kalk  slurry)  will  raise  CA  by  more  than  5ppm  a  day.
 but,  I  have  better  results  using  Tropic  Marine  bio  calcium.

 Mg  =  Ok
 Alk  =  Low  ,  Target  for  atleast  8,  Use  sodium  bicarbonate.  Dose  slowly  over  a  week.
 Ca  =  Low,  Target  for  400,  Use  Calcium  chloride  di  hydrate.Dose  slowly  over  a  week
 
 Both  these  chemicals  are  cheap  and  get  it  in  any  chemical  supply  shop.  Soda  Bicarb  can  be  found  in   most  grocery  store.
 
 Use  the  online  calculator  on  reefcentral  for  exact  quantity.
   
 Using  Kalk  slurry  will  shoot  up  you  Ph.

 I  like  to  purchase  test  kits  for  Ca,  Mg,  Alk.  Can  you  guys  suggest  good  test  kit  brands  for  the  above?
 Thanks

 Rahul,
 I  know  alk  and  CA  are  low.  that  was  not  what  i  was  asking   Chuckle  
 I  use  sodium  bicarbonate  and  purposely  stopped  and  let  alk  fall  because  i  suspected  it  was  blocking  my  ca  from  going  up.
 
 I  know  PH  will  rise  with  slurry  my  friend   Chuckle  
 but  that  is  not  a  problem  as  long  as  the  change  is  within  0.2  points.
 
 anyways,  what  i  was  asking  was  
 I  dosed  slurry  of  1  teaspoon  calcium  hydroxide  (analysis  grade)  in  300ml  of  water  daily  for  1  week.
 why  dont  i  get  a  rise  in  CA  even  though  i  dose  slurry  every  night?
 i  purposely  reduced  alk  from  high  (8-9+)  to  current  5  as  i  thought  this  was  the  cause  of  my  CA  not  rising  with  addition  of  kalk  slurry.
 
 I  doubt  the  testkit  is  wrong
 I  get  better  results  with  tropic  marine  bio  calcium
 I  am  sure  of  the  quality  of  the  kalk  as  i  tested  it  with  a  test  kit.
 
 
 can  you  tell  me  what  can  possibly  be  wrong  when  i  dose  kalk  slurry?

 hi  amit
 you  can  use  salifert,  elos,  seachem  for  CA  /  MG  and  ALK
 
 you  can  even  use  red  sea  for  alk  as  it  is  significantly  cheaper  and  I  have  seen  it  to  be  accurate.
 
 
 however,  let  me  tell  you  you  dont  need  very  high  CA  for  a  rich  growth  of  coralline.

 T5  are  really  good  optioin   make  sure  you  mix  some  actanic  lighting  as  well   it  will  inhance  the  colour  of   Zoanthid's  ....
 Arcadia  T5  is  one  of  the  best  option  i  would  say  but  on  expencive  side...  but  realy   satisfys  with  the  output.....
