With RO you'll have very low GH and KH. With RODI it's probably 0, so you won't have much of anything to lower.
What's your KH?
So gonna use an RODI for my discus as mmy water is not very ideal for them, and I was thinking to remineralise my RO water with this: https://www.devotedly-discus.co.uk/a...39.html#SID=69 . I want to use it with the goal of lowering my pH and gH. You guys think this will be good?

My tap kH is 180ppm
Why do you need to remineralize?
At my age, everything is irritating.
I would remin with a little tap water.
