Beager Pool Test Strips, 6 in 1 Spa Test Strips Hot tubs for Total Chlorine, Free Chlorine/Bromine, Total Alkalinity, Cyanuric Acid, Total Hardness Water Chemistry Tester 50 Count

Comes with 5 individually wrapped packages of 10 sticks. Used these twice this week and it changed colors. We tested them by the amount of chlorine we have in the pool and added some then checked it again and the color got darker. Overall great buy.

I have a hot tub and this is the only ones I use. They are easy to use and easy to read. The value is awesome. The are really accurate.

I got these to use in our hot tub, and they work great! They are easy to read and give consistent results.

Very easy to use and accurate...I compared one to the pricier ones I normally use and the results were the same.

After purchase, I compared the results with those from our local pool shop and the strips was right on. Saves me trips to the pool supply.So happy!!

Purchased for our spa. Arrived very quickly. Exactly what I want and needed. Very easy to use. Will purchase again.

I need to check the level of chlorine and other stuff in the tiny pool regularly. These are quick, accurate, and cheap.

It works, it will give you a basic idea of what's going on, and I find out that the PH reading is pretty accurate, and also it come with sealed couple bags inside, it is very good idea. And better than other brand that I purchased before.
