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

We've used other strips, but these are the closest to a true reading that we have found. We've taken our water samples in to a pool supply store of which they read our water thru a machine that gives very accurate results. These strips have never failed and are as close to the machine results as you can get. We know we can 100% rely on accurate readings here at our home all summer long.
