EASYTEST 9-Way Pool Test Strips, 140 Strips for Hot tub and Spa, Accurate Testing pH, Total Chlorine, Free Chlorine, Bromine, Alkalinity, Total Hardness, Cyanuric Acid, Salt and Copper

Great price for these test strips. Not a big name but the quantity for the price and accuracy of the strips is great. Helps me to know where my water is testing, if the clarity is off, and what I need to adjust. Strips were so easy to use and results were very quick. They are the same size as any other strip you'd buy and no problems reading results. Expiration date was fine. Very pleased with this purchase for my inground, chlorine pool.

I have read that these strip tests are not accurate enough to keep your pool water in the condition required. I have invested in a professional test kit and tried these in comparison to the test kit and the results are closer to each other than I expected. If your not willing to take the time to use a test kit this brand will get you a good result.

I have a weekly pool service but atill decided to get my own test kit to see if the pool guys is actually doing what he’s supposed to. Well, i started asking the pool guy to send me a pic of the test strip every week, which i personally think should have been done in the first place so owners know their pool’s chemical balance.So i matched the pool guy’sntest result against this one from amazon and they’re pretty spot on. His shows chloring level a bit high (about 2 shades darker than what it should be) and mune showed the same shade for chlorine.I would highly recommend getting your own test stripes even if you already have a pool giy. This way you can at least check the balance of chemicals on demand.

The has 140 7-way strips, but only 5 copper and 10 salt. I bought it especially to get the copper and salt tests. My bad, I did not read close enough. Be aware.

Ran one test on a newly filled spa and prior to adding any chemicals. I had no difficulty with the color matching. Is it accurate? That I can't say without taking a water sample someplace to compare, but based on what I know about our water supply, it seemed right.

They arrived and they are what they say but it's really hard to read the writing on the bottle because of the size and the color blend. I use the test strip but then I didn't know what to do with it because there's no instructions on anything so I guess I need to add instructions somewhere on what to do with the reading

Is a good tool to measure swim pool chemistry as compared to a well known pool supply in San Diego.Happy with the product.

I bought these strips instead of competing brands in part because of the CYA test. I want to monitor the levels between visits to the pool store. However, the strips still show levels <30 when the store’s test places the level at 66. In other words, the strips are worthless for measuring stabilizer levels. I’m very also seen some inconsistencies in measuring alkalinity.I will not buy again.
