Review on 🌡️ Seachem pH Alert Test Kit for Freshwater by Jacki Reichmann

Bought for each of my two aquariums which have different pH levels depending on the chemicals I use. The instructions say it takes 30 minutes but after 2 days in the tanks I was told the two tanks were identical. So I took one and put it in a small glass of water with some baking soda - it should have registered a high pH. But if you look at the pictures, this product barely reads 7.0. Two different chemical tests tell me the water is well over 7.6. (The API shouldn't read above this, but the blue in the tube is darker than the highest on the chart, and the Nutrafin test looks darker than its highest of 9.5.)
