I never heard that harder water will affect discus. If you bring discus
to fast
from hard water to soft, they will be killed. Normaly you need to
aclimate a few 
hours before you can put discus in the tank. 

How many discus have you introduced to your tank?

That seem to be normal.

I don't think so, if you like to bread discus, you have to investigate
in RO. 
For keeping it isn't necessary.

IMHO it is posible that your discus get infected by bacteria.
