Guide to Buy the Best Pool Test Strip

1. What They Test For

You need to know what you want to test for when choosing pool test strips, as different types will test for different things.

Some pool test strips will test for only total chlorine and pH. However, others like the AquaChek 7-Way Pool and Spa Water Test Strips can test for almost all the crucial pool chemistry parameters, including free chlorine and total hardness.

Therefore, the specific parameter you want to test should guide you when deciding on the test strips to buy. Remember that there is no value in purchasing a 7-way test strip kit when you only want to know your pH level.

2. Testing Speed

A good test strip should give you results within a short time to ensure you spend your time fixing the pool chemistry if need be instead of trying to figure out chemical levels.

The good news is that most will change colors in just a few seconds, meaning you can have the results ready in under a minute.

It takes around 15 to 30 seconds for the paper to change color, but it is essential to check the results immediately as the color can fade quickly, leading to inaccurate interpretations.

3. Accuracy & Consistency

Accuracy and consistency are perhaps the most crucial characteristics of a good pool test strip, as they ensure the results you get are actionable.

No matter how fast a test strip changes color or the number of elements it can test, it will be of no use to you if it cannot deliver accurate results consistently.

Here accuracy means the color change should reflect the actual level of what you are testing. On the other hand, consistency means that the results will be the same when you test again using a different strip.

It is crucial to know that test strips are quite subjective as people interpret colors differently, and some are color blind. However, some companies solve this problem by providing an app that allows you to upload an image of the color you get for accurate interpretation.

4. Ease of Use

Overall, pool test strips are pretty straightforward to use as you only need to dip them in water and interpret the color change you get. However, things are not always that exact as some can be easier to understand than others.

Pool test strips that use a color chart with a scale that includes light to dark colors to indicate saturation levels will give you an easier time. It is easier to match the color with the right one on the chart with such test strips.

Some manufacturers will go a step further and provide clear directions on how to hold the strip over the chart, making the job even easier for you.

Bottom Line

With the best pool test strips, you have a quick and inexpensive way of testing important parameters like pH, chlorine, alkalinity and water hardness. Regardless of what parameter you plan to check, there is something that will work for you on our list.

That said, the JNW Direct Pool and Spa Test Strips are our top recommendation. These test strips can test up to 7 parameters, and they are easy to use thanks to the clear directions and come with a free mobile app.

However, for those that just want to know the salt levels in their pool to ensure their salt generator is working well, the AquaChek 561140A Salt Water Test Stripsare ideal.
