7 in 1 Swimming Pool PH Test Paper Multipurpose Chlorine/PH/Bromine Test Strips Swimming Pool Water Tester Paper

It's a good idea to do a test, write down your readings, and then take a sample from your hot tub to a pool supply for verification, especially when buying a new brand of strips.

I like that you can align the strip vertically on the side of the bottle. The test srips with the chart on the curve of the bottle are annoying to use.

Keep indoors when not using to preserve strips and the colors (sunlight bleaching).

I have had a home pool for 61 years and was a certified pool operator for 10 years. For the first time in many years had to reach out for professional help thanks to strips from a chlorine manufacturing brand that were inaccurate.
Our pool sparkles again, but we will have to have the pool resurfaced. I blame that on the other test strips. These will be my go-to strips from now on.

We have been using test strips that were good but costly for the amount of strips you received. We switched to these strips. And have been very pleased. I love the color grid and how easy it is to read. One second in and no shaking. Love this product.

This product is much cheaper than the strips I buy at the pool store and work just as well. Definitely buying again.

I ordered these test strips for our outdoor pool. They are exactly what I wanted. Each strip tests for the Chlorine, Bromine, and Total Alkaline. Even though we don't have the pool open until next month, this is exactly what I wanted!

In the back of the bottle are color coded strips to compare what comes out of the pool to what each strip should read. Also on the back of the bottle has exact instructions on how to use the test strips. This is such an easy way to test the pool water weekly. I highly recommend these strips for those who have a swimming pool and/or spa.
