The Pro-Kleen Hot Tub and Spa Scale Stop prevents and effectively removes limescale deposits that may build up in your hot tub, especially in hard water areas. 

An unbalanced pH level can cause significant limescale build up on your hot tub / spa surface which is unpleasant to look at and more importantly can damage your pipe's performance.

The build up of limescale often occurs after a water change, especially in hard water areas. The main reason for this is due to the pH of your house water - it is likely to be unbalanced.

ScaleStop effectively removes and controls all limescale deposits. It is completely neutral and will not affect bromine or chlorine levels within your hot tub or spa.

This unique limescale removal formula prevents and removes limescale deposits caused by mineral precipitation which (due to relatively high water temperatures) rapidly builds up on spa surfaces. 

Available in: 5 litre bottles
