Total Water Hardness Test for Pool, Aquarium, and Drinking Water, and Improving Water Softener Efficiency, Hard Water Test Kit

Why Is Testing Water Hardness Important? You may have felt the effects of hard water, literally, the last time you washed your hands. Depending on the hardness of your water, after using soap to wash you may have felt like there was a film of residue left on your hands. When using hard water, more soap or detergent is needed to get things clean, be it your hands, hair, or your laundry. You can also notice some spots or film on glass dishes after unload them out of in the dishwasher. When hard water is heated, such as in a home water heater, solid deposits of calcium carbonate can form. This scale can reduce the life of equipment, raise the costs of heating the heating the water, lower the efficiency of electric water heaters, and clog pipes. Measuring the Total Water Hardness with AQUAX Test Kit The AQUAX has been designed in One-Reagent (Hardness Indicator Buffer Solution) for easy, quick and correct determination of water quality by Titrimetric Method. The easy drop-and-see application provides reliable results within few seconds. TEST METHOD Fill the test container with the water to analyzed, shake for two or three times and pour off. Fill 5 mL water sample to be analyzed. Add 1 drop from hardness indicator Buffer Solution and shake the test container. a) If the water sample color turns into green-bluish, no hardness is present. In this case, finalize the experiment and report it as Zero Hardness. b) If the water sample contains any hardness, the color will turn into pink-reddish. If the color turns pink – reddish continue adding hardness indicator Buffer Solution drop by drop shaking after each drop and observing the color. When the color turns into green-bluish finalizes the experiment. RESULT: The number of drops spent during the experiment is recorded as amount of hardness in German unit (°dH). 1 drop = 1 German Hardness= 17.8 mg/L CaCO31 dH (German Hardness) = 1,04 GPG (Grains per Gallon)

• Easy, simple to use and reliable water hardness test: AQUAX total water hardness test kit uses just two components: a water hardness indicator solution and a water test container (no microspoon or additional container), making the kit an accurate and easy-to-use test to determine water quality in pools, spas, aquarium, and industries where water hardness is important.
• Accurate results in seconds: Unlike paper test trips that can be difficult to read and match against color charts, AQUAX hard water test kit uses the easy drop-and-see testing method where the color changes in a single drop to reflect the water hardness, thus providing reliable results within few seconds. Easy-to-read instructions are included with each package.
• One hard water test kit, multiple water hardness tests: Each container contains 100 drops, enough to perform multiple tests, depending on the level of water hardness.
• Accurate and reliable test method: AQUAX uses the Titrimetric method to determine total water hardness. The available Calcium Bicarbonate in the water could be calculated as well (read the instruction at the back side of box). To convert the hardness from German unit to Grains per Gallon use the following formula: 1 dH (German Hardness) = 1,04 GPG (Grains per Gallon)
