JNW Direct Hot Tub Test Strips - 100 Tests, pH 7.2-7.6, Chlorine, Bromine, Hardness & More - 6-1 Pack - JNW Direct

I ordered these test strips because of the great description they were given. Their performance doesn't even come close. I only use chlorine in my spa, yet I continue to get bromine readings on the test strip. They do not accurately reflect the chlorine level in the water nor do they accurately report the pH. Their app is also pathetic. These strips have caused me to have more problems with the spa water than I would have using another brand of test strips.

Good for daily use. Don’t buy more than one pot per year. They deteriorate

Good value for money

I've been using test strips for my hot tub for 20 years. Must have used a half dozen different brands. I always had trouble reading them, especially for pH, until I tried these. The clarity of their results is second to none! And they seem more accurate too, when others are inconsistent at best.

I had been using test strips from this company that were a year old and stored in my pool house, which is not airconditioned. My readings were not accurate, and after spending time reading about test strips, I knew I needed to get a fresh container. These have been much more accurate, although I have had a challenge getting the pH and the Alkalinity strips to agree. The pH was continually low, even after adding a pH increaser several times.
