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)

During the years of taking care of my pool I came to the realization that no testing kit gives the correct chemical information of pool water. I use three different methods, calculate the results and use the average needed to treat the pool. Having a salt water pool, I find this measuring strip to be the most accurate predictor of salt content.

Work very well. I've been using these for several years and my pool always look great.Keep the Cl and other tests in range and you won't have an issue.My local store wants $10.00 more for these!

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.

Could be cheap.

These test strips are very convenient, quick and easy to use. These are accurate as long as you wait 15 sec like the directions recommend.

I've bought several of this product from Amazon and from brick and mortar stores and have never been disappointed.

This product is very good for testing your chemical levels in your pool.

Good quality
