Specialty Test Kits
Our Specialty Kits typically focus on measuring one type of chemical and are useful when you only need to test one special factor like hydrogen peroxide or phosphates.
Our specialty color-matching test kits and drop-count titrations give straightforward answers. They are available with 3/4 or 2 ounce reagents.
Ideal Hardness Levels
The ideal calcium hardness in pools should be between 200-400 ppm and spas 150-250 ppm. If your pool falls below 150 ppm, you should adjust your hardness level.
DescriptionThis is a Pentair Rainbow #1200 Specialty Test Kit for Total Water Hardness using a drop test and visual method. Testing parameter indicates total hardness in PPM or grains. The reagents in this kit are 1/2 and 1 ounce. This kit comes in a compact box with instructions.
Calcium hardness is a necessary component in pool water because it helps prevent leaching out of certain substances in pool equipment. It works in conjunction with alkalinity and pH. You would balance alkalinity, pH, then calcium hardness in your pool, in that order. That is because adjusting alkalinity often affects pH. Adjusting both alkalinity and pH often affects your calcium hardness.
