### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I use it for pre-treating my water for home brewing.
  

*by J***O on Reviewed in the United States on April 20, 2018*

Works for my home brewing.  I use it to create a PH solution (6.8) that I put in a small mason jar with the appropriate amount of distilled water.  I keep it in the fridge in the dark for up to a year before making a new batch.I use this to test my mash PH (with a digital PH meter that must be calibrated before each brew) and pre-treat my water prior to brewing.Overall it's cheap, stores forever, and way cheaper than buying the liquid solution.

Use it, rinse with distilled water, and wipe with a paper towel every time you change solutions. You will contaminate it after the first 1to 3 dips. Don't save it! You aren't doing yourself any favors. Always a good idea to check against a good known meter.
