Can you please tell me what you keep you  
*can't think of word*   
(water parameters maybe?) 
 
Nitrite, Nitrate, PH, KH, GH, Ammonia etc! 
 
Just invested in a test kit for Mum, as she seem's to have a bit of trouble with discus   
So we would like to know what our tank water should be testing at! 
 
Thanks in advance!
