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

These test strips were inexpensive and include most all of the items you need to test. I like to know all the levels, not just chlorine and PH. The one thing with these though is you don't read them right after you dip them in the water. You must wait at least 30 seconds for accurate results. Then come back and read it after a minute. Other brands say read immediately but not these.

Easy to use and read. I love the bigger bottle with more strips, I use probably 3 strips a day to test water before and after adding chemicals and they tell me exactly what I need to know. Great value for the money. Would buy again.

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.

This strips work great for testing the water in my hot tub!! You get a lot in the bottle too, so it lasts quite a while!!

Not sure how accurate this is but it has the most useful info.My skin hasnt burned off while im in the pool so i think its working well :)Save your money and do you pool maintenance yourself!
