Underwater Treasures Floating Glass Aquarium Thermometer

Fish can't tell you when the water's drifted too warm or too cold — but a temperature swing can stress or kill them fast. The Underwater Treasures Floating Glass Aquarium Thermometer gives you an accurate, easy-to-read measurement, floating upright or mounted with a suction cup.

Check it daily and keep your tank in the safe zone.

• Accurate glass aquarium thermometer
• For freshwater and saltwater aquariums
