AquaChek 551236-02 Pro Silver Swimming Pool Test Strips, 2-Pack

We used to buy these from our supplier. These are the most accurate strips I've seen or used on pools. We check customers pool water with these when our computer is down.

Worked as it's supposed to

I have checked the reading of these against the liquid drops method and these work great. They are accurate, quick and easy to use. Highly recommend.

I use these in the pool to check the water and they seem to be more accurate than other strips I have used

Love these strips. I have learned a lot about pool care from pool school on youtube (Kenny). He recommends these test strips and so do I. They are way better than anything I have bought at walmart, lowes, or local pool store. And because they are on amazon this is a good deal too. Great value for the money. Easy to use. Easy to read. Functional. It may not be for you if you don't need to test much, but I like to test water quite a bit.

I've been using this brand for about four years. I do pool maintenance for a living. These are great. I haven't tried many others but have had better results from these every time I had to use other brands.

Better priced than pool warehouse, accurate readings for your personal pool or business.

It’s so easy and fast to use. Detect the chemicals in the pool, making easy to keep it safe. Perfect for pool cleaners!
