Cold Plunge Test Strips, 4-in-1 Water Quality Testing Kit, pH, Alkalinity, Hardness, Hydrogen Peroxide. Evaluate Your Cold Plunge Water Quality with A Single Strip. Smart QR Calculator to Help You

I recently tried the Caplide Cold Plunge Test Strips, and I’m impressed! They’re super easy to use and give a clear, accurate reading every time. I love how quickly they react, so I don’t have to wait to know the water quality before taking a plunge. The strips feel durable and precise, making maintaining my cold plunge routine simple and stress-free. Definitely a must-have for anyone serious about tracking their cold plunge water conditions!

This product is a game-changer for anyone with a cold plunge. Before using it, our water would go bad within a week, forcing us to drain and refill constantly. The online water calculator takes all the guesswork out and gives accurate results every time. For a small price, you get consistently clean, balanced water—and way less hassle. Highly recommend.

I bought these mainly for the H202 test, but it doesn't work very well. The color changes significantly over the 60 seconds window in which the instructions say to monitor the results. The other items appear to be a more consistent test.

These 4-in-1 Cold Plunge Test Strips can be reliable when they work, and reliable and convenient tool for monitoring water quality, testing pH, alkalinity, hardness, and hydrogen peroxide. They are easy to use, the problem is some of them simply do not work. The included QR code links to a calculator for interpreting results, though it references additives like baking soda and hydrogen peroxide that may not apply to all users. While not as precise as lab-based tests, the strips provide accurate enough readings for home use, including hot tubs, and pool water. It comes with a generous number of strips at an affordable price.

It is hard to write an amazing review about test strips. They either work or they don’t. If they work, and these definitely do, then they are easy to test and read. These work well and I like the fact that they have 4 tests. I was curious, so I tried them in my hot tub, and they seemed to work for that also since they matched my hot tub test strips. This makes sense because I am basically testing water, so being able to use them for both is an added benefit.

Seem to work ok for PH and alkalinity. When I dosed the pool with hydrogen peroxide, the test showed significantly less than expected, at 10PPM. Before I dosed again, I tested the strips with 5 drops of 3% peroxide in one 8 oz cup, 5 drops of 12% in a second cup, and a teaspoon of 12% in a third. All tests showed exactly the same results at around 10 ppm. My third test cup should have turned the pad black. Picture shows 2nd and 3rd test results. Don't trust these for your pool or spa testing.

I needed to test the pool water, and this is exactly what I needed. It works great and gives accurate readings. It's a decent value.

These strips are easy to use and give quick results. I like that they test pH, alkalinity, hardness, and hydrogen peroxide all in one. The QR calculator makes it simple to interpret the results. The strips are individually sealed so they stay fresh. Great tool for keeping water quality in check.

Easy to use and keep track of the water quality in my cold plunge ….brrrrrr
