Invert the ice cube tray and run some water over it. That will thaw just
enough of the outside of the cubes to let them fall out. You could also
just leave them out for a few minutes. More expensive trays don't work any
better. They just last longer. Water hardness doesn't have anything to do
with it, and pH does not make water hard. The pH is a measure of the acid
or base in the water, though hard water often contains alkaline materials.
I have very hard water but it is well balanced.
