Tetra HT30 100 Watt Submersible Aquarium Heater

Tetra HT30 100 Watt Submersible Aquarium Heater has an electronic thermostat that automatically adapts to keep the water at a perfect temperature. You don't enjoy being in water that's too cold or too hot for comfort, and neither do your fish. If the water in your tank is too cold, it leads to a slowed-down metabolism for your fish. This results in them becoming sluggish and sleepy. If the water in your tank is too warm, it leads to a fast metabolism. This results in fish being a little too lively and hyperactive. The HT30 100 Watt Submersible Aquarium features an indicator light to let you know when it's running and heating the aquarium. The heater will also shut off automatically if there's an electrical short, ensuring everyone's safety. This heater is ideal for 10-30 gallon aquariums.
