Easy for beginners
4 of 5 found this helpful The directions are very plain and easy to understand. All you need to know is an understanding of colors. Just take a sample of the fluid to be tested and add some drops of the Test Indicator. Compare the color of the sample to the chart on the back and see your pH. Be aware that the value won't be exact (like 5.8 or 7.4) It will just tell you an approximate value of acidic, neutral or alkaline. Then you can add pH UP or pH DOWN to adjust the fluid your sample came from. Be aware that the pH UP and pH DOWN are very concentrated and it might only take a few drops to adjust a whole gallon of fluid. I was very pleased with this product.
