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

These test strips are quick and easy to use, with clear color indicators that are easy to read. Results are available within seconds, which makes routine testing convenient. They test all the essential pool parameters and help keep water chemistry balanced. A must-have for pool maintenance. Very reliable and user-friendly.

These are my preferred test strips for checking our hot tub. They are accurate and easy to use.

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.

Good readings

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.

I use this on my pools...has given spot on readings....

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.

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.
