Scale is more commonly known as hard water. This is caused by high concentrations of calcium, magnesium, and other metallic elements. This is commonly seen when clear drinking glasses turn white and spotty from being washed or white crust forms on the sink faucet. This can also affect your spa by creating a crust in your spa’s plumbing & heater or forming a sandpaper feeling layer on the seats.
There are general guidelines listed by the United States Geological Survey to determine if you have hard water. If you test your water for hardness with a test strip and the result is between 0-60 mg/L you have soft water. If the result is between 61-120 mg/L your water is considered moderately hard. A result between 121-180 mg/L is considered hard and if it’s greater than 180 mg/L its considered extremely hard.
SpaGuard’s Stain and Scale Control enables spa owners to prevent stains caused by iron (red/brown tint), copper (green tint) and manganese (brownish red), as well as scaling caused by a high level of calcium.
Scaling can occur with high calcium hardness, high water temperatures and/or high pH. The minerals drop out of the water and rough, sandpaper textured, spots appear on the spa surfaces, circulation and filtration systems and heaters.
