Bree, you can save yourself a ton of $$ and use a Brita water filter to bring your high PH down to a 6-6.5 by only running tap water through it! I've been battling this desert water for many years now and until I found out about Brita's water system I either bought bottled water or used PH down products which both are a pain in the ass! I bought a 2nd filtering pitcher a few months ago to cut down on the filtering time...they're only 16 bucks at Walmart!
