Does chlorine in tap water kill yeast? Does chloramine kill yeast? Specifically Lalvin 71B wine yeast? Is it OK to use filtered tap water (Culligan filter) to re-hydrate yeast?

Everyone knows that reverse osmosis filter strips out the minerals from water, but no one on Google is telling the way to adding them back into the water. I have been drinking reverse osmosis water from a year and its tds rate is also 25 which is pretty good, but it is not hydrating me and I've seen many research on Google about stripped minerals. Can anyone tell me: what should be put in water and how? Is there any …

My brother and my father both brewed the same beer at the same time in the same general area. General area being each at their own home, but separated by about 20 miles and they are in different counties. They used the same bag of yeast, the same bag of grains and everything, just to try to make it consistent. The equipment was essentially the same, my brother being newer at homebrewing than my father. They both used the same …

I just installed a reverse osmosis and deionizer water filtration system, and it is extremely slow. I calculate that it will take 3-4 hours to filter out 10 gallons of water. I am planning on filling up two of my 5 gallon plastic buckets the night before brew day, and snapping a lid on it. So 5 gallons of water will be exposed to air for roughly 1.5 hours while it is filling, and be exposed to the air inside …

I have a reverse osmosis and deionization unit that is able to filter my 450 PPM TDS tap water down to 0 PPM TDS. It has been about three months, and my TDS reader now gives 3 PPM TDS. Do water filters decay at a linear rate for the various compounds it filters out? For example, if my TDS reader read 10 PPM, and I was to analyze a sample of water at Ward Labs which told me that my …

I went and built a version of this filtration system, but the only filter I could find at Home Depot was a 5 micron. The guy in that thread seems to be using a .5 micron. I have been using water coming out of a Brita pitcher (which I love the taste of), however it is very cumbersome to do it this way, which is why I wanted to do this. So I have a few questions concerning water filtration …
