The most essential testing equipment for shrimp keeping.
TDS pen will check the solvents that is dissolved into the water that is not water. Too much TDS your shrimp will have molting issues, too little TDS your shrimps will molt and cannot form a proper shell back. TDS does correlate to gH but not pH. Different remineralization products will have different gH and TDS. It is essential to know your range and keep it stable.
Measures total dissolved solids (TDS) and temperature.
