Soft water will have higher ca. I bypass my home water softner and feed the rodi for this reason.I have been using RO water which is also softened. I have now added a DI stage, so will be using that going forward.

The whole point of a water softener is to remove Ca and Mg, right?

This is good article about the subject
Thanks for the info. Look like my understanding is wrong.That's for fw tanks. I asked Spectra Pure about this before. They told me it is better for the RODI unit to use soft water vs hard water. There is a test you should run to determine which flow restrictor to use for your water conditions.
