I only use RO and rain water, all my problems stopped and I was letting the chlorine evaporate. I suggest staying away from tap water, especially in hydroponics.
COf,
Spring water is often full of minerals. Water marked "drinking" or "purified" is usually RO water and of course there's distilled which is self explanatory. So avoid spring water unless you know about it's content first.
Regarding tap water. You should get a water report from your city/county. It may use chloramine rather then chlorine. In which case, letting it sit for 24 hours won't do a thing. Chloramine requires more active removal. Aquarium places sell the chemicals needed to treat and dechlorinate water.

yes..just run to the store..or let the water sit for bout 4-6 hrs.. how fars the store?!..
The chlorine needs/should be evaporated if growing 100% organically as it kills the beneficial microbes/bacterial in the organic soil/microherd.
if using distilled or r/o water, you need to return cal/mag or you will end up with deficiencies.
no. for cuttings, tap water is fine.These are unrooted cuttings. If i go and get purified water do i need to add calmat to the water?
no. for cuttings, tap water is fine.
