SHOULD I use RO-DI water in a plantless freshwater tank?

[CMOS]

Howdy All,

I have a full 5-stage RO-DI system left over from my former marine tank. Should/can I use RO-DI water in my plantLESS freshwater tank?

Any benefit?

Thanks,
CMOS

IMO no, RO removes minerals your fish need. If you do, you can buy a additive to restore the minerals.
