About This

• 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)
