AquaChek 1 Minute Phosphate Test Kit
Available in store only
The most accurate method for phosphate testing: a one step, one minute, phosphate test.Â Even very low levels of phosphate can feed algae and create problems in pool water. Test for phosphate once a week as the concentration in the water can increase rapidly due to rain, debris or bather load.
Results in a minute!Â
For a clean and healthy pool, test the water at each end a minimum of twice a week!
