Does anyone have a profile for the tap water in Austin, Texas?
Or know where you can find such information?
Thanks,
John

Profile looks like lake water, so yes you should be fine, just run it through a carbon filter. I'll post a pic of my filter rig when I get home.
Thanks Z. This may be the simple addition I've been looking for. I'll try to remember to post back on my findings. My beers have just been a little off and I'm thinking it's the water. Round Rock water is pretty bad and I've only been using a standard charcoal filter.
Hey Z, I tried your technique adding 20mL of 10% phosphoric acid to 8.75 gallons of water (yielding a 6 gal. batch). No idea about the beer yet (it's a lager, will be a while on that). My efficiency seems to have suffered massively, though I'm not 100% sure if it's the pH, or something else. (E.g. I have no control over the crush, may have undersparged a bit due to a late decoction).
He recommended 0.32 mL of 75% acid -- You added 20.0 mL of 10%?
I've had great success with an RV filter, 1/4 Campden per 5 gallons (for chloramines), and just a 'touch' of residual Star San (it's 780ppm Phosphoric Acid after dilution).
Well to be fair he recommended .32 mL of 75% per gallon. Which I calculated to be 2.4 mL of 10% per gallon, or right around 20mL for an 8 gallon treatment. Did I do that wrong?
