EASYTEST Pool and Spa Test Strips, 150 Strips Pack for Hot tub-Test pH,Total Alkalinity,Free Chlorine and Bromine, Accurate 3 in 1 Pool Water Testing Kit

I have found that the Hardness, Free and Total Chlorine, Alkalinity, and pH are pretty close but the Cyanuric Acid is basically useless as it is for most paper test strips from my understanding. CA showed zero when it was actually about 80ppm when I first tested. I have the TaylorK-2006C which is perfect for fine tuning your chemicals and shows far more precise numbers but it's also $125 so I only use it to get my CA and alkalinity. I also bought a separate electronic salt meter that shows pH, etc and the strips are close but when adding pH down, I refer to the pH reading on the electronic meter so I don't add too much. But for what they are these test strips are the cheapest and best way to keep track of your pool's readings.

These work and are simple to use. They give a clear reading.

These test strips are great! Cost effective and accurate. The fact that they test the water for 7 total different things is great as well. It’s been helpful in getting my water super balanced.

They work good and are pretty accurate for a while. I keep them inside and air conditioned but they seem to be a little inaccurate after being open a couple months. I check my pool twice a day and it still takes a while to use them all. They are accurate and I will continue to buy them, I just wish there was a better way to preserve them.

This is a great priced item that allows me to put chemical in my hot tub reliably. Super easy to use, lasts a long time for months. Even it you are testing everyday. Easy to reorder and quick shipping.

Easy to use and accurate according to my pool store.

Works okay for a general reading but the accuracy is a bit off. I took a water sample to my local pool store for testing and received a reading that is different than the strip.

Great test strips. Love that they show water hardness. You get a more accurate reading of water quality.
