NEW! Test Strips, 3-IN-1, Copper/pH/Alkalinity
Pool Check Copper 3-in-1 is the world's first test strip designed to measure the low-range Copper levels used with our Mineralizer Copper/Silver sanitizing systems. Combined with pH and Total Alkalinity readings, Pool Check Copper 3-in-1 satisfies your testing needs where others fall short. Simply dip one test strip into your pool or spa for 5 seconds with a gentle back-and-forth motion. Remove the strip and shake once, briskly to remove excess water. Wait 15 seconds and match to the closest colors.
