Pool and Hot Tub Test Strips - Medical-Grade Precision 7-1 Pool Test Kit - Testing pH, Free Chlorine(Bromine), Total Alkalinity & Cyanuric Acid & More - Pool Water Test Kit

We decided to change over our spa to bromine--instead of an expensive spa chemical system that we had been using. So we needed an accurate way to test the water for bromine.After reading reviews and comparing prices, I chose these test strips. The dispenser makes it easy to grab a strip to use. And the results are quick and seem accurate. What more can you ask?The color comparison chart is right on the dispenser, so it's easy to keep up with it. And it's simple to read results-- since you just have to compare the strip color to the dispense color chart. (They do suggest that you use daylight for this. But it seems to work okay in artificial light, too.)You get a lot of strips for the money, so I'm happy about that. The size makes me not feel that I should scrimp on testing as often as I like.So far, our water looks clear and bright using the test results. We're happy!

These testing strips are affordable and trust worthy. They help keep my hot tub water balanced.

These work well, and were a great value. The colors aren't quite as bright as the more expensive ones, but they are easy to read, and just as accurate.

These strips are attractively priced, come in a dispenser type container, and are easy to read and compare to the gauge colors on the bottle.

We have had no issues with these strips. Works great.

These strips are easy to use, and I feel like the colors are easy to compare to the color chart.

This product works for its intended purpose, but some sticks were missing test squares.Also, remember, these do not test total chlorine. I’ll be purchasing a more complete strip next time.

This is a very easy to use and very quick water tester. If you use chlorine tablets in the pool then cyanuric acid builds up in the pool. By the end of the year there is so much cyanuric acid that chlorine builds up to toxic levels. Best way to get rid of both is to drain water during the winter rains in California. When I start the Cyanuric and chlorine is high and after few weeks of rain and draining through the overflow pipe the levels keep falling. I can check cyanuric acid, chlorine , PH and carbonates. With these test strips I will be able to use less of chlorine tablets. Awesome product.
