This doesn't address which water to use - but I've found an easy way to remove the cloudy film that gets deposited on the feeder. I put a little - several tablespoons - of white vinegar in the empty feeder. Then I fill it with water and let it sit for 5 or 10 minutes. It does a pretty good job of dissolving that cloudy deposit.
