JNW 7-in-1 Pool Test Strips, 100 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

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!

Strips do do not accurately read levels. By the time I realized this, return window closed.

I find these strips are very accurate, but the colors get strange if you try to use them from one season to the next. We keep them indoors except for the 2 minutes of testing/adjusting and the colors don't fade necessarily, but rather change completely (especially for chlorine levels -- instead of the "new" pink, the ones from last year are brown). The cost is great, so I don't mind replacing each spring. 150 strips is more than enough for the summer even given the large number we use at the start of the season.

I've been buying a different brand for years .. because of price gouging .. I was forced to shop around .. I feel real fortunate that I took a chance on these .. the quantity for the price made me suspect .. I was paying .. I think I remember over $20 for 100 strips .. Very pleased with this purchase .. these strips are spot on accurate and the quantity is unbelievable compared to the other 1USE strips I was way over paying for. DYI POOL OWNERS .. AS I'VE OWNED POOLS FOR OVER 25 YRS .. I TELL YA . YOU CAN TRUST THESE STRIPS .. HIGHLY RECOMMEND

very good

Work well. Developed color could be more vibrant though.

It is inexpensive, fast, and easy. Accuracy is questionable though, and that is problematic for me. I think I have gotten mostly accurate readings over the last several uses, but I did not double check all the measurements to test if what I think is correct or not.I cannot rely on these tests strips for an accurate reading of free chlorine today. In the first picture, the color range result for the free chlorine test strip looks like 0-.5ppm. It is the third row (the text strip is longer than the bottle). If I solely relied on this reading, I would have added chlorine to increase the chlorine level.That would have been a mistake. Yesterday, the free chlorine reading in my pool was 3.44ppm, which is a little high. I live in South Florida, and it rained yesterday and overnight, so I expected a small drop in free chlorine, but not this. I tested the water, immediately after this test strip reading, with a digital meter, and the free chlorine reading is actually 2.51ppm.I bought this product hoping to lower the amount of times I use more expensive test strips for my digital meter. Unfortunately, that expectation was too high. I would only use this product in between tried and true testing for a red flag.

Works as expected - easy to read and use.
