Add to RO/DI Water?

[me-n-my-fish]

What do you add to RO/DI water, if anything? I remember hearing that u have to add some stuff the the filter takes out, but for the life of me i can't remember.
TIA

I have heard about remineralization of RO/DI water prior to adding it but I dont have any experience with it. I have never done it so I don't know for sure.

in my auto topoff i just add reefbuilder for alkalinity every other day and a little reef complete for calcium the other days, seems to work fine at keeping my levels stable.

I use kent PH buffer to regulate ph/alk on RO/DI.

kewl, thanks. I have been saving up for a RO/DI sys, and i think that this weeks check will put me over the edge. So i am trying to get everything set up for it.
Thanks again.
