AquaChek7-Way Pool and Spa Test Strips - Silver Pool Test Strips For pH, Total Chlorine, Free Chlorine, Bromine, Alkalinity, Total Hardness, and Cyanuric Acid - Water Quality Testing Kit (100 Strips)

Fantastic! Measure all 6-7 pool chemicals at once. Fast and easy. About 25 cents per strip, 100 per container, and need to use only 2 a week. Lasts for 2 years of pool use.

These test strips are very convenient, quick and easy to use. These are accurate as long as you wait 15 sec like the directions recommend.

Work very well. I've been using these for several years and my pool always look great.Keep the Cl and other tests in range and you won't have an issue.My local store wants $10.00 more for these!

Easy to use. I am already using the SureTrack strips. Basically the same thing but I wanted to look at possibly a more accurate system that includes Total Chlorine which the SureTrack strips did not. I only gave this test strip 4 instead of 5 stars because the Cyranuric Acid (CYA) and Alkalinity were significantly off.I tested multiple times on the same day. For AquaChek I got the exact same results each test. I compared to results attained by professional tester (Leslie's Pool) from one of the samples. Alkalinity was reading 0 on all the AquaChek test. The professional test showed 80 ppm. SureTrack test showed about 80 ppm as well. I was expecting the AquaChek to be brown (0 indicator) or atleast light green (40 ppm) but it was just mostly white with a little tint of brown. I've tested maybe 12 strips now. All AquaChek CYA reading the same color. Perhaps for my bottle the test material is bad for detecting Alkalinity.The AquaChek was pretty spot on for the other test. I will say for SureTrack and AquaChek the tints are fairly close on PH. At least the SureTrack had a 7.2 , 7.5 and 7.8 reading. The Aquacheck had indicators for 7.2 to 7.8 only. So there is a little more guessing on PH with AquaChek. Since 7.8 is generally the high limit, this should be okay to test for predicting maintenance. Though my goals are to keep PH at 7.2-7.4 for pool comfort. So the SureTrack helps better with this one.Prior visits to Leslie's Pool, they recommended to use a bottle to get test from arm length below pool line. CYA tends to float on top. Your best accuracy supposedly comes from sample an arm length below pool line. I had money to burn so I compared multiple test of samples taken from bottle at arm length below water line and dipping test strips arm length below water line. No difference on AquaChek test. All strips from hand or bottle sample read same for CYA. The indicators were at 0 and 30-60. The color was between those two indicators so I'd guess 15 ppm. The Leslie's professional test was 50 ppm. The SureTrack CYA has indicators for CYA are at 0, 40, 70 and 100 ppm. I'd guess 40 ppm for all of them. Maybe the bottle test samples were a slight shade darker than hand test samples. I only mention this last paragraph in case there were any questions to the sample methods on CYA.For me, both test systems were great. And I will use on a weekly basis or every few days to verify chlorine and PH for sanitary and comfort.. Also to verify hardness which is important on warranty for plaster/aggregate. If you get indication you are consistently outside the ideal ranges, I would definitely recommend getting a professional test to verify problem and professional test again after any treatment. I was told to use the strips probably more often like every day or two for a week after treatment to keep a close eye on treatment long-term effectiveness. I have to do professional test every month for warranty purposes. I'll benchmark accuracy with each professional test so I will have more data in the future. I'll update this post for anything else I find.

Great product and seems more accurate than similar products. Simple to use and read the chart.

During the years of taking care of my pool I came to the realization that no testing kit gives the correct chemical information of pool water. I use three different methods, calculate the results and use the average needed to treat the pool. Having a salt water pool, I find this measuring strip to be the most accurate predictor of salt content.

A great product to test your pool chemistry without having to go through an extensive kit test to get multiple results.Tests 7 different chemicals, provides results within seconds, and if you need to check one for better accuracy, then you can breakout your pool chem kit and seek a more accurate result.Overall very happy with the purchase and saves me time from going to the pool store and having the water tested weekly.

My father-in-law was having water chemistry issues with his pool. Although the local pool supply company will perform water quality testing for free, it’s always a hassle to collect the sample and drive to the store, wait for the results, and drive back. These test strips give me all the information I need, especially free and total chlorine, and they are quick and easy to use. May be a little bit less accurate than the analyzers they use at the pool store, but certainly adequate for daily monitoring of pool water chemistries and you have your results in about 15 seconds.
