EASYTEST 9-Way Pool Test Strips, 140 Strips for Hot tub and Spa, Accurate Testing pH, Total Chlorine, Free Chlorine, Bromine, Alkalinity, Total Hardness, Cyanuric Acid, Salt and Copper

great

First time using strips to test pool water. I’m not blown away at the accuracy. Seems pretty broad and hard to tell exactly where you lie on any of the color scales. The CYA seemingly doesn’t ever work. I never see any change in this color. (Confirmed at pool store test that I do have proper CYA) Best case scenario is I can see if I’m roughly close to chlorine and free chlorine levels with these.

These strips are easy to use and give you a holistic image of the pool chemicals.

It’s easy to use, but deciphering results is not so easy. Some of my samples colors don’t match any of the “guide” samples. I don’t feel like you can get any accurate results with these strips. Pretty much a waste of money.

Good product
