Pond Thermometer by AquaScape
The submersible thermometer is a Koi lovers good friend. Many people feed their fish when water is too cold for the Koi to metabolize it properly. With this thermometer you will know when to start feeding your fish in the Spring. We recommend to start your fish with a wheat germ based food when water temps are 12.8 degrees Celsius/55 degrees Fahrenheit. When water temperatures reach 15.5C/60F you can start the Koi back on a higher protein diet. When water temps dip in the fall below 15.5C/60F it is time to reintroduce the wheat germ based food. There should be no feeding in water colder than 12C/54F. Feeding the wrong food in too cold of weather can lead to fish illness & death.
