How come my fish only get white spot during night time. in the morning they're ok ? ph 8.2 at night. :notsure:

Usually its the opposite. How long have you had these fish?
Were they quarantined before being placed in the display tank?
Sounds like you have a problem with ICK.

they have been there for more than half a year, and recently developed these problem after i added a new piece of lr. but they still behave normally and don't scratch themselves. i just switch from coralife to coral marine salt, is this the cause ?

Sounds to me like an ich problem. Do you know if the LR was kept in tanks that had fish or shared filters/water with fish tanks?
