Snow!

[Castellop123]

Filtering snow through active carbon is the same thing as using tap water... Just dechlrinate the tap water and you're fine, like fishkiller said, snow is dust/a particle frozen over by the snow, so your water still has the same kind of particles and dirt that any other type of water would. Tap water is actually safer for you fish because it's less acidic, remember not all fish enjoy acidic waters...

Yes, but I am going to keep plants and fish that prefer soft, acidic enviroments...

Not that we get that much rain either...

Use a mix of rainwarter to tapwater to get your desired conditions.
