first off, your kh is fine. you do not need to reduce your kh, especially
since you are going to use co2.

2nd, what kind of ph buffer are you currently using? Your ph is too low
to
be natural with that kh. you will not be able to use co2 charts until you
get that additional buffering out of the system.

I have a water softner connected to the house main water supply, and
recently (the last six weeks) I'm using this for water changes
