Scale remover from the premium surespa range of hot tub products.
surespa ScaleAway helps to prevent and remove scale deposits which can build up rapidly on spa surfaces, particularly at high water temperatures, when the spa water is particularly hard.
Apply this product directly to your spa water whilst the spa pump(s) are turned on to aid distribution.
Initial dose : 25ml per 1000 litres spa water.
Maintenance dose : Apply 15ml per 1000 litres of spa water weekly.
NB Spas treated for heavy scale will need the filter cartridges to be cleaned thoroughly with a powdered filter cleaner a week after treatment.
If the spa water becomes saturated with dissolved solids then ScaleAway will become less effective and a water change will be necessary.
