seachem prime for RO/DI water?

[JarviZ]

I have Seachem Prime for emergencies, but directions say to use it for during water changes to deal with Copper, heavy metals, etc.

But I do water changes and top offs with RO/DI water. Should I still be adding Prime?

No, IMO it is not a good idea and is unnecessary.
If for no other reason - when using this product you cannot get an accurate ammonia reading of your water.

x2...no need if your TDS reading is 0....

I agree, do not use with ro/di. Its totally unnecessary
