So I tested my water at a pool store a few weeks ago. (said ph was 7.4)
Then I had been using those 10$ 4 way HTH test strips they sell at my local Walmart. ph seemed to be 7.2 but I was worried the strips weren't accurate. So I bought a drop based ph and chlorine test.
Are all phenol red ph tests kits made equally or are some better than others? As I am getting what seems to be an 8.2 and strips still look 7.4ish...
