EASYTEST7-Way Pool Test Strips, 150 Strips Water Chemical Testing for Hot tub and Spa, Accurate Test Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine

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!

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.

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.

previously used another brand which was easy to read. This product was cheaper so gave it a try, not happy; am going back to previous brand.After using, along with using previous brand -- It took practice but once I figured out the best dip/wait/see colors, I found the strip was , along with previous brand, close to each other's test so I changed my review. Good but takes practice to get it right. Will order again.

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.

Keep containers out of light, color chart will fade

Be careful before adjusting pool chemicals using these strips. The CYA test is not at all accurate. I used these strips to increase CYA only to find that after more precise testing using a Taylor Water Test Kit, the CYA was way over already!!! These strips are NOT accurate for CYA. Period. Now my water has very high CYA levels because these strips are bogus! Note: I usually read mid level reviews before purchasing a product. Wish I had for these strips. Others have complained about this as well. I will never use them again.

These test strips worked perfect. Quick and easy test and very accurate. I will be using these test strips from now on.
