Hard Water & Scale Removal Filter

Hard Water & Scale Removal Filter x {{ model.addToBasketQuantity }}


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"

Use the Hard Water & Scale Removal Filter when filling your spa or pool to remove calcium and magnesium from the water replacing it with soft sodium instead.


  1. Simply attach your garden hose to the filter & fill your spa using a slow to medium flow rate.
  2. The slower the fill the more effective the process.
  3. Use in conjunction with No Scale & Insta 4 Way Testing Strips for regular monitoring of hard water & water balances 


  • The filter is compatible for all sizes of hot tub and swimming pools up to 15,000 litres.
  • Long Service Life 
  • High flow rate
