Pool Test Strips 7-in-1, 200 Quick and Accurate Pool and Hot Tub Test Strips - Pool Water Testing Kit for Chlorine, Bromine, pH, Hardness, More - All in 1 Swimming Pool Test Strips by JNW

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.

I find these to be as accurate as any other similar strips. The chlorine, the hardness, and the alkalinity are easy to read. the ph is marginal. The CYA is difficult to read. Overall, these are good but not as good as a liquid chemical test. I run a saltwater 25k gallon pool.

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

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.

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. 😉

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.
