Hardness and Scale Control
If you keep the TA and pH balanced you won't need to worry about scaling unless you live in a very hard water area.
If your water is very soft, you might need to increase the calcium hardness to unsure your sanitiser works efficiently and to control foaming.
AquaSPArkle Spa Hardness Plus - 1kg£10.95
AquaSPArkle Spa Hardness Plus increases the calcium hardness of hot tub water.
When the calcium hardness level is below 100mg/l (very soft water) the water can become corrosive leading to damage to the hot tub finish and equipment. The tub surface can become abrasive and uncomfortable for bathers.More Information
AquaSPArkle Spa ScaleAway - 1lt£16.65
AquaSPArkle Spa ScaleAway prevents and removes scale deposits caused by mineral precipitation on hot tub surfaces and pipework.
Scale deposits can build up quickly due to high calcium levels (hard water) combined with high water temperatures, in the same way as a kettle scales up in a hard water area.More Information
