I wouldn't count on a filter being able to take metals out of your water. For swimming pools there are filters available that can take particles out down to 3 -4 microns. But even if you have such a filter, to remove metals reuqires addition of a flocculant which will bind to the particles and...
As I read through, I started to wonder about the water angle as well. I can speak a little bit about water chemistry, but not with regard to brewing... only with regard to keeping a swimming pool clear.
You mentioned you're on a well, so it may be worth peeking at the plumbing all the way...
Whaty about something like this?
It stands to reason that there could be varation in the temerature in different parts of the pot (which is why we have convection, i guess), but can you measure the surface with an infared thermometer and feel good that it's close enough?
I could find...
Yeah... it dawned on me last night that I can't use the same test anyway. The scale on the comparator only goes down to 6.2 or so. If your pool water has a pH lower than 6.5, you *&^%$-well sure better not swim in it. Plus, it will corrode the bejeezus out of all the metal components in your...
I used StarSan the first time on a batch I brewed two weeks ago. Since I'd heard you could store it for later use I saved it in some plastic milk jubs. I had no idea it was supposed to be clear -- mine clouded up instantly.
How are you testing the pH? I assume I can use the same...
