Do you want to test/measure/re-measure every water change, every day? No. Just "Let it be!"

But, you do need to leave it be for now.
You now know that using the R/O water is what was killing your buffering capacity. You know how to keep your pH in the neutral range and keep your KH high. You have all the tools you need. Just go back to business as usual. Regular water changes, etc.
