What's the best way to prepare water for my betta fish tank?

Should I let already room temperature spring water set open before I transfer my betta to another bowl?

If you don't use municipal water, you can "age" water for 24-48 hours before use. A conditioner (StressCoat, NovAqua, etc) is still recommended to prevent stress. The water should be temperature matched as well. Room temperature water is too cold for Bettas. They do best between 78 F and 80 F.
