Salt-Water Pool Test Strips Kit: 125 Counts 8-in-1 for Salt Water Pool Testing Kit, Salt Pool Test Strips for Hot Tub Spa Testing Salt Chlorine pH and More

Works well. Easy to order without trip to pool store

These test strips are accurate for our salt water pool. I recently added a Poolrx product to our pool and the strips still read correctly. I’ve had an inground gunite pool for over 30 years and these are the best strips I’ve ever purchased for chlorine, PH, and salt levels.

These test strips are useful for making a quick evaluation of your tank to ensure nothing is seriously wrong. The API test kits showed the following for a tank halfway cycled: - pH 7.0 - Ammonia 0ppm - Nitrite 5ppm - Nitrate 20ppm - GH 12dgh (215mg) - KH 2dkh (36mg) The test strip (bottom strip in photo) showed: - pH 6.4 - Ammonia not tested - Nitrite 5ppm - Nitrate 25ppm - GH 300mg/L - KH 0mg/L Keep in mind that API kits measure GH and KH in degrees, while these strips measure mg/L. One degree of hardness is approximately 17.9mg/L, meaning API said my GH is 215mg/L and KH is 36mg/L. Unless I'm colorblind or doing something wrong, GH should have been one shade paler and KH should have been one shade darker (not really too far off, all things considered) - but when testing my tap water, which is a pH of 8, 7dKH (125mg/L) and 18dGH (322mg/L) according to API, the test strips were dead-on accurate. I cannot tell if the chlorine test is accurate, as our city states that they maintain the water at 0.8-1.0ppm but our area is outside city limits and seems to have slightly different parameters than what is listed on the city website. I would still expect some chlorine, but it did not register on the test. So bottom line, it's reasonably accurate for the most part, but I'd use a different test strip for pH. pH is a logarithmic measurement, so the closer to 7.0 you are, the harder it is to measure. Even API tends to be difficult to differentiate at that value and uses an entirely different test for high pH. Most test strips I've seen use 4 different squares, not one! For *all* parameters listed, I wouldn't expect total accuracy at either the high or low end of the spectrum - but it'll definitely put you in the right ballpark and tell you if something has changed since the last time you tested. I take a picture of the test strip next to the bottle at the one-minute mark, and save all my results for future reference so I can compare from week to week. If something is wrong, bust out the liquid chemical tests.

Works as advertised, good product.

These are easy to use and I love that they have readings for salt. Has helped me keep my saltwater spa clean for months.

It test pretty accurate.

Price easy to read test results

I was trying to balence my pool and I felt like I was never getting it right and chasing my tail for days adding this and adding that. I understand that strips and super accurate. But these strips are way off. I had the pool water professionally tested using a computer and AI. These strips show Tc=5 fc=.5 cc=4.5 ph=8.4+ ta=40-80 hardness 425+ cya=0-50 salt=0 The computer test shows Tc=8 fc=8 cc=0 ph=7.6 ta=135 hardness 250 cya=60 salt=3000 These tests were completed within 30 min apart from each other using the same water equipment with a real-time pool water temperature of 75°. These are in my oppinion are junk and will never buy again. See photos.
