Chemistry question about using softened water ran through carbon block

[twilliard]

Hi all its me again.
Here is a question asking about the chemistry and usability of water that has been filtered through a 20" carbon block and a water softener.
What elements or ions would be left after this process?
Thanks!

From the Wikipedia:

Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds.

Not sure if that's helpful.

My goal would be to be able to fill my new tank with the end product of the carbon/softener system
Thoughts?

That's how a lot of well systems work. Maybe I'm missing your question

At my house, for example, the water comes in and goes through a carbon block. From there it goes to my acid neutralizer and then out to the house. The water is usable as is at that point. It isn't "reef clean" since softeners and neutralizes all add TDS.

Phosphate and nitrate would not be removed, as might not some of the heavy metals such as copper.

I'd use something else.
