Saltwater Pool Test Strips, 0-8000 ppm, 25 Count

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.

Easy to read test strips that show solid readings when in or out of range. When compared to lab water tests, there is some slight variation in ppm to color readings on the test strip, but not enough so that when numbers are compared to lab/water tests that they are out of acceptable ranges. We have had consistently great water test readings across the board since using these test strips. We have even been personally commended by our local water testing facility for the cleanest water tested this season. With these strips, we are able to confidently do our own chemical balancing without as many visits to the pool store (aka the chemical salesmen!!). We could not have achieved this without reliable home test strips. Not to mention, we have saved so much in chemicals from accurate strip readings rather than relying on the readings and recommendations from the pool store alone. I highly recommend these strips to anyone who is looking to balance their own pools at a fraction of the cost of strips (and chemicals!) from the store.

I like these strips. They are easy to read and accurate. They are a good value for the money.

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 pool test strips have made checking our pool water so much easier. I like that they test so many important levels at once, including chlorine, pH, alkalinity, hardness, and cyanuric acid. The strips are simple to use and give you results quickly, which is really convenient when you’re doing regular pool maintenance. Having 150 strips in the container means I don’t have to worry about running out anytime soon. A very helpful and convenient product for keeping up with pool water quality.

I use these test strips for my spa, and they make checking the water really quick and easy. It’s convenient having all the important readings on one strip, including pH, chlorine, bromine, alkalinity, hardness, and cyanuric acid. The results are easy to read, and having 150 strips means I have plenty on hand for regular testing. Great value for spa maintenance.

Worked well for us! I would definitely purchase again. Easy to understand. You just have to make sure to read the results within the first 10 seconds. After that, the results are skewed.

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.

Most 7 in 1 tests that I've come across have been roughly $55 for a 100 pack.. assuming these are affective, it's an amazing find! Very simple and striaght forward to use too.

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!
