First, A carbon filter won't take out anything from water treated by RO or a
quality DI unit.
Second, a water quality report from your local water authority will be
irrelevant once the water has been processed by RO or DI.
The trick to solving your problem here would seem to be a combination of
analysis, observation, and searching the archives about the symptoms you have.
You're missing some trace element because of the RO water, but time and
patience will show you what you need.
