EASYTEST 7-Way Pool Test Strips, 150 Strips Water Test for Hot tub and Spa

If you live in a warm area, be sure to store these indoors. I have a nice waterproof box by my hot tub and tried storing these in it with some of the chemicals. It was fine over the winter, but now that it's above 85 outside, the strips are discoloring. The Alkalinity and PH are WAY off....PH reading is a much lighter orange 7.0 vs actual 7.4, and the Alkalinity reading is much darker....almost 100 points higher! I confirm strange readings with my liquid test kit, so no harm done. Just want to warn others before they start dumping in adjustments and making things worse. The color changes were gradual at first until the temps hit the 90's. The Bromine scale still works pretty well, so at least they aren't totally useless.

The EASYTEST 7 Way Pool Test Strips (150 count) are an excellent choice if you want quick, reliable water testing for your pool, hot tub, or spa. They’re designed for convenience, and real users consistently praise how simple and effective they are. These strips test seven key water parameters — free chlorine, total chlorine, bromine, pH, total alkalinity, total hardness, and cyanuric acid — giving you a complete snapshot of your water chemistry in seconds. Reviews highlight that they’re perfect for routine maintenance, especially before adding chemicals or after heavy use, hot weather, or rain. Customers also love the accuracy and ease of use. The colors develop quickly, the chart is clear, and the no bleeding pads make matching straightforward. Many reviewers mention that the 150 strip bottle lasts an entire season, making it a great value. If you want a simple, affordable, and dependable way to keep your water balanced, these test strips are absolutely worth it. Highly recommended for beginners and experienced pool owners alike!

not an experienced pool person, so I bought these quick strips for our above ground pool. They are great, and accurate. Instructions are easy to use and water testing takes less than a minute

These are the best strips of those that I have tried. Results are consistent and strips are easy to read and match against color chart on bottle. Once the bottle is opened they are only accurate for one swimming season, which for me is about 4 months. Not an issue unless you have to buy them end of season.

These work and the ranges and zones showing OK for each test on the bottle. I have a spa, and I used to use droppers in a pool previously, I’ll never go back. No 2nd guessing in the results. Awesome!!!

Excellent test strips. Give cyanuric acid level along with free and total chlorine along with chemical balance check.

I was trying to see if my girlfriend is pregnant or not and these things didn’t tell us much but I felt like they would have been pretty accurate if we dipped them in a pool or hot tub.

Very convenient for quick routine checks. The color chart is easy to follow and the strips give me a good general picture of chlorine, pH, alkalinity, hardness, and stabilizer levels. They’ve been useful for spotting trends before they become bigger problems. I took off one star because some readings, especially free chlorine, can be difficult to judge precisely from the color shades. Good for regular monitoring, but I’d use a liquid test kit when exact numbers matter.

Quick to use, excellent strip for overall pool health check, chlorine level and pH balance is my primary concerns the others are good to know for fine tuning and comfortable pool use. Durability is good and suitable for pools. Colours on the strip seem accurate enough to make a judgement call on the adjustments that needs attention.

These are great, accurate and easy to use! They have a reading chart on the bottle which is helpful. No issues.

The strips didn't work, kept reading ph wrong. I bought distilled water to double check - consistently read it at a ph of 6. I tried another sample if purified water - did the same again.

I've used twice the recommended amount of chlorine for the size of my pool, but these test strips stubbornly give me a reading of 0ppm. I'll use another brand.

Son fáciles de usar, 1 segundo en el agua y listo y permiten comprobar los parámetros con los colores del bote. La escala de colores se entiende bien. Por cantidad y comodidad, mis 5!
