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)

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.

Accuracy is very good

These are my go to for water test strips for my pool and spa. The colors are easy to read and are the most accurate test strips I have come across. I test my water about once a month at the pool store to compare to the strips. IMO, you don't need the expensive and time consuming Taylor test kits, just get this instead.

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

I've had 6 pools over 45 years. I've tried other brands that give you higher quantity of test strips for a lower price... they are not as accurate and hard to read. The contrast in shades of color are very distinct with this brand and the readings are reasonably accurate as compared to professional testing from Leslie's. If you're looking for a quick spot check of your pool, you'll find these work great. For many years I used the kits with various bottles of solutions and honestly I found them to be too time consuming without the benefit of increased accuracy. Again I'm just a pool owner with many years of experience. Not getting paid or anything like that to post this review.
