While I don't believe in keeping fish in a bowl you should never use distilled water to keep fish in. It will kill them eventually. Tap water is perfect for most fish once the chlorine has been removed/evaporated off. You can do this by simply leaving the water in a bucket overnight. I refuse to waste money on water conditioners.
Arrowhead sells multiple types of water. If you see 100% mountain spring water on their label, then its not distilled. That means it still has naturally occurring fluoride and other minerals in it. If you see Distilled water on label, then the water could be distilled municipal /well water. Do not use distilled water for daily use as it does not have necessary minerals. But distill water is probably better than drinking tap water or spring water as "No Fluoride poison in it!"
The water in my area sometimes tastes odd. What is considered the better choice in terms of pure drinking water? How does bottled spring water compare to distilled water? Whats the difference between the two?
No, distilled water is water without minerals and other impurity's.
Is there any distilled water for drinking that I should stay away from? I heard from a friend there is a brand that has dangerous minerals in them.
No, use distilled water.
Distilled water is said (I've not drunk any) to be tasteless. Domestic tap water has impurities in it depending on its source (hard or soft water, for instance) and chloride is added to disinfect the water and make it safe to be sent to the drinking water taps of the population. Some people won't drink tap water due to the chemicals in it, and prefer to drink bottles of natural spring water bought from a supermarket.
is drinking distilled water harm full for humans
The distilled water is not recommended as drinking water, excepting some situations; also is very expensive.
Drinking distilled water can potentially cause diarrhea in some people because it lacks minerals that help regulate bowel movements.
