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

Using the ones from the pet shop, I was always getting irregular readings. My fish didn't appear to be struggling, but the chemical readings didn't make sense. Low this time, high next time. When I switched to these, I was spot on with the water treatments. Comparing to the pet store brand side by side, the readings were still off.

works well

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.

I really like these strips because they test my salt level. I felt like I was always putting salt in my pool. They are very easy to read and very reliable. They are a great value and help keep my pool on point

This was my first use of SaySummer Test strips vs Hach AquaChek which I have used in the past. They seem to be of equal quality and ease of use. Because of the location of my pool in the direct sun with a typical water temp of 85 degrees F, use of an automatic cover, variable daily use ranging from none to many people and dogs, I check my pool almost daily to maintain chemical balances. I always use a Taylor K2005 test kit and compare to test strips daily. There will be some slight variance in results between the Taylor kit and the SaySummer test strips (or any test strip), but the SaySummer strips are reliable based on my experience

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.

Works great is very accurate except for the salt which is why i bought these. It registers the salt at the correct level even though the salt is very low. Salt is defiantly not accurate.

Works well. Easy to order without trip to pool store
