Strontium can also be added to the water for replenishment as well. Neat, huh? And it works well. Remember, each day it will take the pump a little longer to pressurize the caddy as the volume of water is reduced. Keep an eye on it the first week or so to determine the "quirks" that always develop when you DIY!! I refilled my caddy once a week and let it do it's thing the other six days! Refer to the diagram for specifics.
