At 20 you are probably OK but much more than that could start to be a problem with some beers. I invested in RO because my well runs about 27 most of the time.
If you want to be on the safe side and get it down even more the most practical method is dilution with RO water. In which case, or even if you don't dilute, you may want to increase chloride some. This you can determine in a taste test on the finished beer.
