I think this was in a thread somewhere---using peat moss, commercially available water softening pillows (I think you can get them for different size tanks, they go by number of gallons), a water softener (but this takes out calcium and manganese ions, which your turtle uses), mixing tap water with water that's gone through reverse osmosis.
I don't have this to contend with, so I don't know, but, can the deposits be removed with a little diluted vinegar and some gentle rubbing? At any rate, like you said, it doesn't harm their health. I recently read that harder water is even better for turtles.
