JNW 7-in-1 Pool Test Strips, 150 Quick & Accurate Test Strips for Pool Water, Spa Test Strips for Hot Tub, Chlorine Test Strips, Bromine, pH, Alkalinity, Hardness & More - Swimming Pool Test Kit

These test strips work perfectly and give quick, clear results. I used them to check the hardness of my tap water and my softener system — both readings were accurate and easy to interpret thanks to the color chart. The included eBook is a nice touch, explaining water hardness and maintenance tips in simple terms. With 150 strips, it’s an excellent value for ongoing testing.

I have a small 18' above-ground salt water pool, and although it came with test strips, they were USELESS. So I was told test strips for salt pools are not accurate, but after reading the reviews, I figured I would give it a try. I had other devices to test my water but I wanted something quick and easy to use to give me a "feel" of where my water readings were. These actually did rather well although there were a few readings off that could have been better but it did help me maintain the levels across the pool a bit easier. Simple dip for a couple seconds and wait a bit for the strips to turn. Match it up with the bottle and run from there. It beats chemicals and lots of tools but same time it doesn't exactly replace those items either for accuracy. Would I buy them again? Yes!

These test strips are great. You get the results very quickly. The color change is very obvious and very easy to use. I would not recommend it to test your salt levels as I don't really get a good reading. It always says it is low. All the other tests come out right. Great value for the money. I would try it out and get your salt levels checked from you salt cell or Pinch a Penny.

This works every time giving an accurate measurement of our hot tub water chemical levels. This includes the free chlorine which we needed to keep an eye on since that can be harsh on the plastic jet components. So far, so good. It is also dated so we know it is still fresh and accurate.

Great results and I tried bottle water. I feel there pretty honest so I will keep using.

Product is easy to use, recommended by wirecutter.com. And their customer service was incredibly fast, even on the weekend, answering a question I had. Five thumbs up. 😉

One of the main issues I encountered is that the results obtained from the test strips do not match the liquid test. The accuracy of the readings is questionable, leading to uncertainty about the actual levels of hardness, chlorine, bromine, free chlorine, pH, cyanuric acid, and alkalinity in the water. This inconsistency makes it difficult to effectively maintain and balance the pool or spa water. Furthermore, the quality of the test strips is subpar, as they are falling apart easily. The strips are fragile and tend to break or tear when dipped into the water or handled. This not only affects the accuracy of the results but also adds inconvenience and frustration during the testing process. Considering the price of the product, it is simply not worth the investment. The affordability of having 100 test strips initially seems appealing, but when the accuracy and durability are compromised, it diminishes the overall value. I would have expected a higher level of quality and performance given the price point. While the instructions suggest that the testing process is quick and easy, my experience has been quite the opposite. The color chart provided on the bottle is not always clear and can be difficult to interpret accurately. It takes longer than expected to obtain reliable results, which defeats the purpose of having a convenient testing solution. The inclusion of a free e-book is a nice gesture; however, it does not compensate for the shortcomings of the test strips themselves. The additional information provided in the e-book does little to improve the overall experience or address the issues with accuracy and durability. In terms of usage tips, the instructions recommend keeping the strips away from moisture and closing the cap tightly between uses. Despite following these instructions diligently, the strips still deteriorated quickly, further highlighting the lack of quality and longevity. Overall, I cannot recommend the Pool and Spa Test Strips. The inconsistent results, poor durability, and overall lack of value make this product a disappointment. I would advise seeking alternative testing options that offer more accurate and reliable results, even if it means investing in a slightly higher-priced option.

As a pool owner, maintaining the right chemical balance felt like a constant battle. The JNW 7-in-1 Pool Test Strips have quickly become an essential part of my pool maintenance routine, and I can confidently say they live up to their "quick and accurate" promise. What sets these strips apart is their ability to test for seven crucial parameters in one go: Free Chlorine (yes mine is low in the pic), Total Chlorine, Bromine, pH, Total Alkalinity, Cyanuric Acid (CYA), and Total Hardness. No more feeling like a backyard scientist trying to decipher confusing liquid reagents. With JNW, it's a simple dip, wait a few seconds, and compare to the color chart on the bottle. The colors are vibrant and distinct, making interpretation straightforward even for beginners. I've found the results to be consistently reliable, giving me the confidence to make the necessary adjustments to my pool chemistry. The bottle contains 100 test strips, which is a generous supply that lasts a long time, even with frequent testing. This makes them not only effective but also a cost-effective solution compared to some other testing methods on the market. The packaging is also well-designed, keeping the strips dry and protected from light, which helps maintain their integrity. For anyone who wants to simplify their pool maintenance and get reliable readings without the hassle, the JNW 7-in-1 Pool Test Strips are an excellent investment. They've saved me time, frustration, and ultimately, helped me keep my pool sparkling clean and safe for swimming. Highly recommended!

These are the best test strips I have used over the six years I have had a pool. As well as testing my water, I have tested the strips by adding measured amounts of chemicals into the pool water and checking the change in results. These strips are very accurate within the parameters stated. Very useful to have the CNA measurement which many strips ignore. The colour differentials are good and the strips are very easy to use. Buy these..!!!!!!!!

Worked well, just what I needed to test the effectiveness of my water softener.

Very good product, simple to use and good value.

Nachdem wir uns einen Pool und ein erstes Starter-Set zur Wasseraufbereitung zugelegt hatten, war klar, dass wir bessere Test-Stäbchen zur Kontrolle der Wasserqualität brauchen. Die im Starter-Set enthaltenen Stäbchen waren nicht wirklich aussagekräftig. Nach einer längeren Suche bin ich dann über diese Teststreifen gestoßen. Alle wichtigen Werte sind dort enthalten und können ganz einfach bestimmt werden. Nach Erhalt wurden diese umgehend getestet. Dose auf, Stäbchen eingetaucht, kurz gewartet und abgelesen. Alles sehr einfach und schnell. Sehr gut finde ich, dass die Skala einen Soll-Bereich anzeigt, indem die Wasserqualität liegen sollte. Die vereinfacht alles und man erhält sofort eine Tendenz. Sollte ein Wert aus dem Ruder laufen erkennt man schnell, welcher dies ist und kann so zeitnah reagieren. Natürlich habe ich am Anfang 3 Stäbchen nacheinander getestet. Ich wollte wissen, ob die Ergebnisse reproduzierbar sind oder jedes Stäbchen einen anderen Wert zeigt. Alle zeigten das gleiche Ergebnis. Ich bin sehr zufrieden und habe nun, für meinen Teil, die Test-Stäbchen meines Vertrauens gefunden.
