Hardness
Water hardness occurs as an indirect side effect of various chemical compounds.
Calcium and magnesium are the two primary minerals that make up hardness in
water. Like alkalinity and pH, hardness affects the tendency of the water to be
corrosive or scale-forming. (Scale is a deposit that forms on pool walls and
equipment when the mineral content of the water is too high.) By maintaining the
ideal ranges for hardness and alkalinity, you can keep scale formation to a
minimum.
Low hardness levels require immediate attention! They can be very dangerous to
your system. Water that is not properly saturated with hardness—water in which
the hardness level is too low—will be very corrosive, causing significant damage
to metal pipes and fixtures as well as plaster. You must be sure to balance
hardness before adding any sanitizer to the water. Otherwise, the water will
become even more aggressive (corrosive); it can cause severe damage in a short
period of time.
When the hardness level is low, increase the hardness immediately to limit the
damage of corrosive water. You can increase the hardness level by adding a
chemical like calcium chloride. When the hardness level is too high, excessive
scale formation occurs, and the water may become cloudy or discolored. Elevated
pH and warmer temperatures will increase scale build-up too. If the hardness
level is too high, you can partially drain and refill with fresh water.
The ideal level of hardness for your pool or spa water is from 200 – 400 ppm
(mg/L). You should test hardness when adding fresh water, and re-test until you
have balanced the water hardness properly. After that, test hardness a minimum
of once per month throughout the season. If you use calcium hypochlorite as a
sanitizer, you need to test more frequently to ensure that the level has not
exceeded the upper limit.

spa, contact your dealer.
