surespa ScaleAway helps to prevent and remove scale deposits which can build up rapidly on spa surfaces, particularly at high water temperatures and when the spa water is particularly hard.
surespa ScaleAway prolongs the life of your hot tub by prevent scale damage to pumps, heaters and seals.
It will also help to prevent unsightly scum lines around the waterline and it will not affect the water balance of your hot tub water.More Information
In addition to reduced sanitiser efficiency, symptoms of low pH in hot tub water include skin and eye irritation, excessive sanitiser use and potential corrosion of the pumps and heater with pitting or etching on the spa shell surface.
If the pH of your water is below 7.2 it is important to raise it using pH Increaser.More Information
Calcium hardness is the measure of how much lime (calcium) is dissolved in your water.
The hardness of your spa water will be overwhelmingly influenced by the hardness of the mains water supply to your home and that is dependent on where you live and the source of your water supply.
If you live in the South of England, you most likely have hard water, with lots of calcium dissolved in your source water. If you live in Scotland, Wales or the North of England, you most likely have soft water with a very low amount of calcium in your water.
Hot tub water with very low total hardness (very soft water) can cause etching to occur on the tub surfaces which will become abrasive and uncomfortable for bathers.More Information
Maintaining the Total Alkalinity within the correct range is the key to water balancing when you are using either Chlorine or Bromine as your sanitiser. Low Total Alkalinity will cause the pH to fluctuate widely and make consistent balancing impossible. Alkalinity that is too high will make it impossible to adjust the pH.
Always adjust the Total Alkalinity before anything else.More Information
