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

2nd line not showing great (chlorine). Dumped 8 gallons of shock in there. One day later strip showing very low chlorine. Other colors come out very clear. I do like how it shows all “good” ranges on all the specifics.

It makes it a lot easier to test the pool water. Seems to work

This label is misleading. It says 9 in 1 when it's the same 7 test strip with a few salt and copper strips included. The product is the same as all the other 7 in 1 strips so if it's the cheapest for 125 strips then get it, otherwise don't be mislead by the 9 in 1 label.

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.

great
