This 4 in 1 test kit is ideal for swimming pools and hot tub owners looking for a step up from the domestic pool and spa testing kits. The Pentair Rainbow kit uses liquid reagents to achieve far more accurate test results.One very useful feature of this test kit is the acid demand test. In situations where your swimming pool water is about pH 7.8, performing an acid demand test will let you how much needs to be added to your pool water to restore the recommended pH level.Contents include 1 fl oz No 2 pH reagent, 1 fl oz No 3 pH reagant, 1 fl oz No 4 Chlorine neutraliser reagant, 1 fl oz No 5 alkalinity (blue) reagant, 50 rapid DPD No 1 tablets and 50 rapid DPD 3 tablets. Kit also contains a handy Acid demand comparison table and full instructions.
Never let reagants remain in the test vial, clean and rinse after each test. Hold bottles vertically for proper drop size. Take water samples from a depth of 18" (away from return lines). Test tablets should be white and care should be taken not to touch them as contaminents on your fingers can adversely affect the readings.
