Test your tap water. You might find it’s boringly neutral. Or it could be a secret acid party. My friend’s tap in Arizona was pH 8.8. He calls it “desert juice.”
Test your aquarium water. Fish are snobs about pH. Goldfish like 7.5. Discus fish want 6.0. One wrong number and they stage a silent protest.
Test your coffee water. Yes, really. Coffee is naturally acidic (pH 5). But if your water is basic, your coffee tastes like bitter regret. Fix it, and your morning becomes a hero’s journey.
