Blue Planet Floating Glass Thermometer

Blue Planet's Floating Thermometer is simple to use, accurate and easy to read. You should check your aquarium temperature every 12 hours to make sure that the heater is working at the correct temperature. Low temperatures can lead to white spot disease and even fish deaths. Water that is too hot can also slowly cook fish to death.
