Filling New Tank With Snow?

[MarkoD]

Ok this is probably a stupid idea but I came up with it in the shower

have a new 180 coming this friday and its gonna be hooked up to a 40 gallon sump and 30 gallon refugium....

... my RO/DI only produces 50GPD

so 5 days to fill it up

i was wondering, would it be possible to fill the tank with fresh, clean snow and let it melt to fill it?

as long as the snow is clean, the water should be pure just like RO/DI right?

maybe run the water through a UV sterilizer for a day just to make sure nothing is in it.

what do you guys think?
