After passing through the water conditioner how long will the water remain treated for?

If water is stored in a closed system (ie a water tank), once it goes through a  Salamander Pumps’ water conditioner, it will remain conditioned for 3 months.

The cooler temperature from a water tank helps to slow down the transition of conditioned water going from aragonite to calcite.

Aragonite is metastable, once this has been exposed to normal atmospheric conditions, it will start to convert back to calcite. This happens especially when in contact with fresh water that lacks high levels of magnesium. Aragonite will convert back to its calcite state quicker if the conditions are warmer and drier.
