common opinion

When using distilled or RO water for PDF , it's best to 're-mineralize' it.
Most people soak indian almond leaves in gallon containers.
There are 'BlackWater' additives that can be purchased as well.

For spraying the glass ( never the frogs ) distilled ( supermarket) or RO is fine as it will not stain the glass.

For other frogs..... tap water should be de-chlorinated. i.e tree frogs should not be soaking tap water

For mister buckets..... RO or distilled is necessary as even dechlorinated tap water could "damage the pump"

Tadpole water ( and for water changes ) should be RO or distilled only --- re-mineralized w soaking Indian Almond leaves
