As water evaporates, heat goes with it — typically lowering tank temps 2–4°F depending on room conditions and tank lid configuration. It's the simplest and most cost-effective way to keep a nano tank from overheating in summer without committing to a full chiller.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeads-up:\u003c\/strong\u003e Faster evaporation means faster top-off.
