TDS pen is an instrument for measuring total dissolved solids (TDS) in water. By measuring TDS value, we can know the cleanliness of water body and master the time of water change. The advantage of using TDS pen is that it is convenient and quick, and you can quickly understand the general situation of water quality. However, TDS pen can not measure the pH of water, which may be insufficient for fish tanks that need to accurately control the pH of water.
Different test strips and liquids can provide more comprehensive water quality information. For example, test paper can measure the pH value, nitrate, ammonia nitrogen and other parameters of water, while liquid test agent can detect residual chlorine, nitrite and ammonia nitrogen in water. These parameters are very important for maintaining the water quality stability and health of fish tanks. It takes more time and equipment to use test paper and liquid, but it can provide more detailed water quality information for fish lovers, so as to better adjust and maintain the fish tank environment.
To sum up, it is a quick and simple method to use TDS pen to detect the water quality of fish tanks, but different test papers and liquids can provide more comprehensive water quality information. Test paper and liquid may be more suitable for fish tanks that need to accurately control the pH of water. Fish lovers can choose their own water quality testing methods according to their own needs and conditions.
