I purchased these because the slightly cheaper ones I bought at the store weren't giving me the right readings. No matter how much PH+ I put in the pool it never changed. So I doubted everything else. When I purchased these for cross reference I saw right away the colors were darker. And the hardness was much easier to read. The bottle congress with the chart so there's no need to buy the other one they have unless you want the plastic sleeve that connects to the bottle to place the chat in. I've had these for a couple weeks now. Yesterday I went to the pool store completely confused how my entire pool went from sparking clear, to green in just an hour and a half! I doubted the strips. So they did a water test in a machine connected to their computer and it gave me a read out. Every result the computer gave me was almost exactly what these test strips told me. I am very impressed since so many pool stores will tell you they are junk. This pool store actually promotes buying these exact strips. HOW TO USE CORRECTLY: They told me to take a bowl and dunk it down into the water about half your arms length and place the filled bowl on the counter. Then dip the strip in the bowl quickly. For half a second. NOT 1 or 2 seconds. Doing more than 1/2 a second will dilute the pads too and remove the chemical on the pads and you will get the wrong color.EDIT: I shocked my pool last night after getting back from the pool store so the chlorine levels won't match the paper they printed. I took the photos this morning.

I use Aquachek (there's no 'c') strips to test my spa's water every few days. I'm very happy with these strips, and find them much faster and easier than the other options I've looked at. The bottom of this review explains what the different chemicals do if you're not familiar with them.Pro:+ Easy to use: dip them into your pool to wrist depth, set them flat and count to 15 (seconds), then compare colors.+ Includes all the tests I care about. Hardness, total and free chlorine, PH, alkalinity, and as a bonus Cyanuric Acid which doesn't apply to my spa.+ Colors are easy to read in twilight and lighter.+ Includes a pamphlet with a color chart if you lost yoursCon:- Colors continue to change after the first minute, so you really do want to look at the colors within the first minute or two.What the different readings are used for:TOTAL HARDNESS tells you if you need to add or remove chemicals to make the water harder. Too little hardness and metal in your pool releases minerals. Too much hardness, and it can gunk things up. Usually this is only checked when adding significant water to the pool.TOTAL CHLORINE / BROMINE and FREE CHLORINE together tell you whether you need to 'shock' the pool to free up bound chlorine / bromine, or whether you just need to add a bit more to replace evaporated chlorine. If you add too much and get a high reading, leave pumps running with the cover off to encourage faster evaporation of the chlorine. I got my 800 gallon spa from 20 ppm to 5 ppm in just a few hours this way.pH and ALKALINITY can affect stability of chlorine levels, so good to keep them where they belong.CYANURIC ACID is (I think) an additive to help keep sunlight from decaying your chemicals as quickly. My spa is in a gazebo so I don't use it.Overall, I like these test strips and have been using them for a year or two.

We use these pool strips all through the pool season. They work great and are very accurate! We have a plastic card that’s color coded and can match it up with that after taking the strip out of the water.

The app was steering me wrong. Match the colors manually. Seems pretty accurate when you use your eyes and not the app picture thing.

I use these every day during the summer to be sure my chems are correct. One does have to work fast, as the color will fade, which will not give you an accurate reading. Again...I found this accurate, but you do need to work fast.

I cannot recommend this item.This is not reliable anymore. I have been using this product for many years but the last one messed up my pool. It shows the chlorine levels always adequate or high, no matter what. Even if your level say 1ppm, it shows very high like 5 or above. Something was odd with the chemical levels of my pool, but because I relied on this product for so many years I did not suspect that the test would be bad. Result was that pool got messed up. The test is the most important thing for your pool, it is like breaks in your car, you cannot drive without breaks (well you can of course but it would not end pleasantly!)Worse is I contacted the manufacturer but they referred me back to Amazon, which indicates they cannot stand behind their product.Last, they came up with this app thing, it just does not work, you have to have the color chart, but as I said above, the tests are not reliable!Clearly, there is no way for me to recommend this test!

Works good. Easy to read. Does not run. Like where it also shows free chlorine

DO NOT BUY!!! Useless strips with no colour chart. May as well throw tea leaves in your pool or spa and try and read them. Grrrr

Great system I enjoy to do the test. Which I really do when I have to compare strips to charts.

Ordered this product and didn’t realize that it’s considered a “refillâ€. It is completely asinine that a simple chart wasn’t included either separately or on the side of the bottle. You can download an app but comparing the strip to a screen doesn’t work great. I guess it’s a marketing strategy: pay an extra $10 to get the chart with a plastic cover.

l'échelle de couleur pour comparer les résultats est sur une feuille de papier, aurait préféré que ce soit sur la bouteille directement comme habituel. .Faut faire attention de ne pas humidifier la feuille avec nos mains mouillées, et ne pas perdre la feuille de comparaison.
