What kind of water to use?

I got a tank build going for my nano planted tank I am working on and have a few questions on what kind of water to use. It's only a 3 gallon tank and I plan on having a carpet plant like glosso or HC and maybe some taller stuff in the back. Plan on using Flourite black sand for substrate. It's only a 3 gallon tank and I plan on using excel instead of CO2. Coming from a salt water background RO/DI is what you need to use but in fresh water it looks like that's not always the case. I tested water from 4 different sources and am wondering what would be the best to use. I have my own well and use a water softener with Rust Remover salt. Here are the results:

Straight from Well: TDS - 373 ppm
GH - 21 dkh
KH - 23 dkh
PH - 7.8

After water softener: TDS - 378 ppm
GH - 4 dkh
KH - 27 dkh
PH - 7.8

Reverse Osmosis: TDS - 27 ppm
GH - 3 dkh
KH - 3 dkh
PH - Less than 7.4 (more yellow than 7.4 on API)

RO/DI : TDS - 1 ppm
GH - 1 dkh
KH - 1 dkh
PH - Less than 7.4 again

I bought some Kent Marine Liquid R/O Right that makes RO/DI water better to use but not sure if that's the route to go. Also, since I am on my own well, I don't need to use anything like Prime do I? Thanks in advance for the help. Otto

RO would be just fine. The DI isn't necessary IMO. On the bright side, you are only using enough for a 3g so even if you threw the waste water away, you aren't using THAT much water.

I currently use my waste water for my cichlid tanks. Afterall, it comes out cleaner than it went in!

Thanks for the help guys. I was kind of leaning towards that way since I figured my well was pretty bad. Just waiting for the sand to come in and then the tanks getting filled.
