E-Z Read Pond Thermometer

This deluxe thermometer will gently float in your pond until you're ready to check the water temperature. Pull on the 36" rope leash with anchor plate and you can easily read the large Fahrenheit and Celsius numbers behind the shatterproof lens. 9" long. Registers 30-110°F or 0-42°C.

As the seasons change and pond water temperatures rise and fall, so do the nutritional needs of koi. To make the proper adjustments in koi diet and portion size, you need to use an accurate thermometer to measure water temperature on a regular basis.
