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

I ordered these while using two competitors strips. The first thing I noticed when they arrived, they're made better than the competitors. They're bigger and the color changing pads are separated further than both of the other brand of strips. I can't speak to accuracy vs a liquid test kit, however it seems to match up exactly to the Clorox brand of strips. I stay consistent on how I dip the strips in the water and how long I wait to color compare for a reading. Being color blind, I use an app to do the color reading for me. It's fast, simple and hopefully accurate enough to keep my pool in acceptable range. With 100 testing strips the price is cheaper compared to other name brand strips. I'm happy with the purchase and will be buying again.

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.

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
