JNW Direct Pool Test Strips 7-in-1, 150 Quick and Accurate Pool and Hot Tub Test Strips - Pool Water Testing Kit for Chlorine, Bromine, pH, Hardness, More - All in 1 Swimming Pool Test Strips by

I find these to be as accurate as any other similar strips. The chlorine, the hardness, and the alkalinity are easy to read. the ph is marginal. The CYA is difficult to read. Overall, these are good but not as good as a liquid chemical test. I run a saltwater 25k gallon pool.

it works

These pool test strips are super convenient and give quick, fairly accurate readings for multiple water parameters. The color chart is easy to use, and the strips are individually wrapped, which helps keep them fresh. My only small issue is that reading the colors in low light can be tricky, but overall they make pool maintenance much simpler and save a lot of time compared to manual testing.

I like the fact that I can do the test myself with the pool boy. The color on the strips change, but I still don’t know how accurate this is, but it puts me very close.

These work great to test our pool water, the quality & accuracy seems great. Gives a variety of different results for water quality. They are fast & easy to use.
