I have a 5 in 1 test strip kit but i dont have the color chart how do i read the strips
The charts are usually under the label. Sometimes it's not easy to peel it off without destroying everything. Some dip strip tests have different color charts for freshwater and saltwater. Usually, they do not measure ammonia, and that's a very important water parameter. Ammonia testing usually requires a kit with a sample tube, liquid reagent and color chart.
