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)

Best tool I have found maintaining good chemistry for my salt water pool. Easy to use.

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.

Pool maintenance becomes simpler with these superior test strips. Readings are consistently accurate and reflect true levels of chemicals. This brand might be pricier, but quality matters.

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.

These strips work really well. Like having 1 strip to check everything.

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've had a pool for 20+ years. I purchased other test strips while out shopping this year. After trying them out on water I had tested at my pool place, I returned them and ordered these, which I had used in previous years. These are accurate and agree with the water tests from the pool place, the colors on the pads match match those on the container, and the strips are long enough to get a good grip on without getting near the pads and tainting the results. I will continue to use these, I find them the most accurate.

Quite expensive, not many strips.Readability:able to read accurately.
