Review on Accurate And Versatile - 7 In 1 Test Strips For Pools, Spas, And Hot Tubs - Perfect For Home And Commercial Water Testing by Jarod Lacy

These test strips are not very accurate. I used them to test my water and kept getting weird results. For instance, after it rained it showed my Ph as low. Rainwater raises Ph. It also showed my stabilizer as low even after putting in the amount of stabilizer recommended by my pool place. I took my water in for testing, and the results were completely different from what these test strips showed. I get that test strips aren't as accurate as professional testing, but these were WAY off the mark.
