AquaChek 7-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)

These have been the most accurate test strips I buy. I compared them with the results of my water test that I took into the pool store and they were spot on. One bottle lasted all summer and I was able to keep my pool crystal clear and balanced. They're so easy to use. Dip it in the pool for two seconds then wait 15 seconds. Next, compare the strip results to the guide on the outside of the bottle. It shows you if you're in the appropriate range for these 7 different things.

Reliable replacement for my Hayward pool valve This Hayward SP0714T replacement valve came exactly as described and worked perfectly for my sand filter. Installation was straightforward—it matched up with the existing plumbing and fit securely without extra adjustments. The handle action feels smooth, and the diverter clicks firmly into each position, which reassures me it will last through frequent use. What I really like is that it brought my filter back to life right away. My old valve was leaking and made backwashing a hassle, but this new one sealed properly from day one. The build quality is solid, and the labeling on the top is easy to read when switching between filter, backwash, rinse, and waste. One thing to keep in mind: this is a direct replacement for Hayward sand filters, so double-check compatibility with your model before ordering. It’s also a little bulky to handle during installation, but once it’s in place it’s not going anywhere. Bottom line: A dependable OEM replacement that fixes leaks, restores proper function, and makes filter maintenance simple again.

Have used many times w/ great results.

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.

Very happy with these. Easy to use. Accurate readings that are easy to see. I compared them against the kit where you put the drops in and found they were spot on. I feel like the amount you get for the price is a good value.

These strips work great, just be sure to check the expiration date at the bottom. These recent ones will last two years, previous one only 6 months. Colors easy to read, were accurate after taking water sample to Leslie’s pool and comparing.

I had a chemical service company for my pool the last 30 years. Their prices went up 3 times in the past year so I cut them loose. I used to be a certified dialysis technician so I've been approaching pool water much the same way as preparing dialysate. I tried two cheaper brands of test strips but they were very inaccurate. The colors on those were way off. These strips are much easier to read and compare colors for accuracy. I still run up to the pool store but in between their analysis, I use these and trust them. They are worth the price to eliminate guesswork.

I own a full Taylor test kit but I use these strips to just quickly check the pool through the summer. I’ve found that these are quite accurate on all tests except for pH. The pH isn’t far off the scale is just too close for my visible eyes to be able to easily see discernible differences. I’ve compared these directly to the Taylor kit about 3-4 times and these strips are always close to the same results of the Taylor kit. I have a salt pool so these don’t test salt. So I bought an electronic salt/pH tester. The combo of that and these strips hits everything I need. I’ve bought these twice and will definitely keep using them in the future.

Accuracy is very good

These are the most accurate test strips out there. I have used around 10 different brands and these are the best. The color chart is very close to what actually shows up on the strip, compared to guessing with others.

I have lost confidence in these strips. They were constantly reading very high chlorine levels which dictated how much chlorine I added to the pool but I was having recurring algae problems. I eventually bought a test that uses tablets to get a reading and that test said the chlorine levels were very low, which makes more sense. Hopefully my algae problems are now over.

Having wasted my time with swimming pool branded test strips, this are amazing! They are very accurate and even more accurate than the Jed chemical kit I have! Highly recommend!

Simple to use, saves trips to the pool shop and allows incremental seasonal adjustments of chlorinator/ sabiliser /ph & acid
