Hard water is not good for your spa.
As well as uncomfortable scale on the wall of your tub, white calcium marks on your jets, & limescale build up in your filter it also damages the internals of your spa, especially the heater.
Eventually limescale will become present in the tub itself in the form of "calcium flakes"
The Pure-Stream Filter is easy to use when filling your spa or pool to help prevent hard water from forming & will work well with no scale and 4 ways testing strips to keep hard water under strict control.
