R/o vs tap water
 

I was wondering if anyone uses a product by(seachem) that "remineralizes" your R/o water. I use R/o but if i was to use tap then i would get all the extra minerals and who knows what else.

I ask this because I find some of my water tests are low IE: Magnesium is 1300 and still checking the rest.

I don't think that 1300 is low for Mg. I usually shoot for between 1250 and 1300.

Al,

Salt will remineralize your RO water. That's what it's designed to do.
