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

These test strips are super easy to use and give quick, accurate results. I like that they cover all the important levels like chlorine, pH, alkalinity, and hardness. The color chart is clear and matches well. Perfect for regular pool maintenance, and the price for 150 strips is a great deal. Definitely a must-have for any pool or spa owner!

Fairly accurate; not as precise as store test, but close enough to know if pool chemical balance is ok between trips to the pool store. Examples: pH was measured at pool store to be 7.4; strip matched between 7.2 and 7.8, with color about mid-way between the two extremes. Alkalinity was 100 at pool store; strip matched the 80-120 region, with color about mid-way between the two extremes. Expiration date is 2.5 years from purchase (3 years from manufacture); instructions say to use strips within 150 days, but I'll have leftovers this year, so I'll see how they do next season.

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.

These test strips are convenient for quick pool checks, covering chlorine, pH, and more. They’re not always spot-on compared to liquid tests, but they’re great for everyday monitoring. A useful tool, just don’t expect lab-level accuracy.

So so so easy to use. I will say I’m not colorblind. These strips are easy to use, you just dip it in and then compare the colors on the bottle. The readings have always been accurate and the sheer amount of strips for the price is amazing. I use this every single day and it has never failed me. PH levels and other markers are important to ensure skin health and hot tub safety. These strips are sturdy and don’t flop over from the weight of the color changing stickers. Definitely a must have for those needing an easy way to maintenance a hot tub or pool.

These test strips seem to work really well. Just dip them in the pool water, wait a few seconds and compare the colors on the strip to the colors on the bottle, which are much easier to compare than some of the other test kits I've had in the past..... on these ones the color changes on the strips are much more in line with what they look like on the bottle so are a lot easier to get accurate levels to make the needed adjustments.... and then verify the changes.... nice.

They are quick, but the ranges they give you are huge. When I read it the color changes quickly. I wouldn't buy these again. Maybe they work for someone who wants a very broad range of where their pool's salt level is.

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
