Fznkrag Alkalinity Pool Test Strips, 100 Strips

Product is 100% accurate. How do I know? Because I compared test strip findings to a professional water quality testing lab and the results were identical. Very impressive. Strips are affordable, reliable and easy to use.

Arrived quickly, easy to read

Reopening my pool was so much easier with these strips. Worked great and convenient!

Perfect for all season testing! Comes in individual packs of 50 so the strips don't expire or dry out!

Perfect for all season testing! My pool is crystal clear. These strips are so easy to use and read.

Total junk. Free chlorine is supposed to be white to dark blue. All of the strips turn different shades of brown, never blue. pH and Alkalinity show opposite readings from different test strips and from test kit with liquid drops. Can't trust it at all. All test strips were in sealed foil packaging, but none were any good.

I bought these to test my spa. Luckily, I still had 2 other methods of testing and both those agreed with each other. What I found is, at least on the test strips I received, the chorine and total alkalinity reading were accurate, but the pH read low. My actual pH was 7.8 and these strips read 6.8. If I would have relied on these strips for adjusting my water, I hate to think what would have happened. In the trash they go. Never buying these again.

These strips are junk. I have some HTH strips left and they read chlorine and normal alkalinity and ph in our hot tub used 3 strips from the first pkg and they read very low or nothing on all. I can smell the chlorine in the water and the strips read 0.

the colors don't correlate, chlorine is supposed to be white, light to dark blue but all of my readings are all green. I'd like to hear from someone why this seems to be a common issue as I see other say the same thing.

Each strip is individually wrapped! Why isn't there other options besides sending from china?
