As I have posted before, my water here is VERY hard and has so much iron and gunk that a white bucket filled with water will have a bunch of black specks in the bottom. I was given a brand new reverse osmosis device for my kitchen, but I am completely clueless about what to do to the water after I use it. I think my beers are pretty decebnt so far but they do have an off taste in near all of them. The only constant besides equipment is the water. Can someone point me to " BREWING WATER FOR DUMMIES" or something along those lines?
