What Charles meant was that all you need to do is keep using it and it
will convert by itself because it will acidify and then only the wild
organisms will survive.

Use it, feed it, use it again. As long as you've got the action you're
describing it's good to go.

Just remember,it's not going to stabilize for a long time--it'll
certainly raise dough, but it won't mature/develop.

Which is what would happen if you started a starter from scratch as
well, so as long as you've got something, use it.
