I read where one person used a TDS meter in the aquarium to monitor it. Said that it was kepted between 100 and 200 ppm.
I just started using RODI water and wondered if this could be utilized in the amount of tap water to be added when doing a water change?
If so, is 100-200 ppm good for plants and fish?
Tank TDS/243ppm
Tap/479ppm (well)
 
I'd say a ppm of 100 -200 works. If you've been having success adding RO water with your tap which appears to be prettyb hard .. then I'd say stay with it. How is the tock in your tank doing?
