AquaChek®
Total Hardness test strips have two pads, allowing you to measure both
Low Range, up to 120 ppm (mg/L), and High Range, from 250 to
1,000 ppm.
Compare our test results against your favorite liquid kit. Just dip an
AquaChek® Total Hardness strip in pool or spa water for one second and remove
it immediately. You get test results in seconds!
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.
