Should I use my Mayu swirl to aerate my brewing water for a complete fermentation process?

I recently started making craft beer as a hobby. I lived near a lake and used the local water for my first batch. However, my first keg had no body, and it tasted horrible, and lousy water led to an improper fermentation. I am looking for a way to improve my brewing water quality. Can I use my Mayu swirl to improve my brew water?
