Can You Use Bottled Water in a Fish Tankの全体像を丁寧に掘り下げてご紹介します。

Imagine you’re a betta fish. You live in a perfectly balanced puddle. Then, BAM! Someone pours in “Glacier Melt” water.

That “pure” water might be too acidic. Your fish will pout. It might even get fin rot from stress.

Fish are 80% water themselves. They literally can’t escape what you pour in. No pressure, right?

Spring Water vs. Distilled Water: The Showdown

Spring water is like a wild party. It has minerals, gases, and random stuff. Some fish love that. Others get indigestion.

Distilled water is the opposite. It’s so pure, it’s boring. It has zero minerals. Your fish will actually leach minerals from their own bodies to survive.

That’s right. Distilled water can suck the life out of a fish. It’s like feeding your fish a diet of only air.
