RO water what to add to it?

[Elmo Peach]

I have 5 gal of RO water what do I need to add to it or where do I find the info? Not sure if I just use it as is or do I add salts? So many ???

If you are extract brewing, I'd recommend using it as is.

If all grain brewing, you're going to need to add salts, and perhaps acid (depending on the grain bill). There's no one-size-fits-all answer here. I'd suggest reading the Intro to Brewing Water Treatment that can be viewed/downloaded here.

For extract, start with just the RO water. Over time, you could 'season to taste' with small amounts of CaCl / CaS04.
