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.

It floats!

Every pond should have a thermometer floating in the pond or skimmer to determine when to add bacteria, fish food and when to do other maintenance chores.

Water temperature determines when to shut off the bottom drain, when to shut of the filtration pumps and when to add a pond winterization kit.
