話題沸騰中の What Is the Ph of Purified Waterについて、詳しいまとめを分かりやすく掲載しています。

I learned about purified water’s pH the hard way when I tried to keep a betta fish alive. Bettas are fancy little divas that prefer water around pH 7.0. I filled the tank with purified water because I thought it was “clean.” The next day, my fish looked at me like I’d served him vinegar. The pH had drifted to 6.2, and he was not impressed. After adding a mineral buffer and some stress-relief drops, he forgave me. Now he swims in slightly alkaline water and acts like a king. Lesson learned: purified water is great for humans, but terrible for most fish unless you fix its pH.
