With water temperature being such a critical factor for the well-being of fish, it’s important to have a good thermometer. This Marina Floating Thermometer is designed to float in the water in a vertical position for an accurate reading. It comes with a suction cup for optional installation on your aquarium glass.
It provides temperature readings in Centigrade and Fahrenheit. It also has a safety zone temperature range indicator for most tropical fish.
For fresh or saltwater aquariums.
