I like the system and I love the product. We use more than I thought we would, even the dogs drink about 25% more, their water bowl has measurements. But the strangest thing is the ice. Mine is a typical ice maker that produces the rows of "dragon teeth" With the RO water the ice is all but the inner 25% clear and is very brittle. It used to be that the ice bin was full of these rows of teeth, now they are almost all broken down to single tooths and the ones that aren't break when dropped in a glass. Not at all like the old ice. This is great because the ice dispenser used to make a lot of noise breaking the rows of teeth up to fit down the chute in the door.
So, why is the ice so brittle?
