A very special thermometer for use in outdoor fish ponds, especially Koi ponds. Water temperature is a extremely crucial element of Koi keeping, as it determines the feeding schedule best suited for the fish.
Overfeeding can easily occur at certain temperatures, resulting in pollution of the water. And under feeding Koi will result in stunted growth, lack of vitality, and poor resistance to disease.
Easy to read color coded temperature scale. Shows proper fish food selection all year.
Summer usually means increased pond water loss due to evaporation, which of course leads to topping off our ponds more. You should always add dechlorinator when topping off the water level of a pond. Any amount of chlorine (such as that found in treated water) can be harmful to your fish. Even if it is not enough chlorine to mean immediate death of the fish, this chlorine can still cause harm to proper gill function.
