A pinch of Prime during Winter/Spring time is all I use.

This is true, our tap water is brilliant. Especially Richmond's (less time traveling through pipes). Tested at only 12TDS, and didn't even register for chlorines.
However, I switched to RO/DI water a couple of months ago. I switched without knowing what our tap water was really like, I just assumed my tanks could benefit from higher quality water. I would actually still stick with my decision though. I ran a waste bucket for the first few weeks as a comparison, and let me tell you, that water STUNK, while the reservoir water had no scent and registered 0TDS. Even though we have very clean water, there are still clearly some nitrates floating around in there that
could have an impact. I would also like to include that since making the switch, an algae problem has drastically decreased.
All that having been said, I have been keeping freshwater for nearly 10 years without RO/DI (obviously not as substantial of an ordeal), and never even questioned my water quality.
