Submersible Aquarium Heater
The temperature of your aquarium is an important factor in the comfort and well-being of your fish. Unlike humans and other mammals, fish do not produce their own body heat. They must rely on the temperature of the water to maintain their body temperature. This makes it very important that you keep your aquarium at the proper temperature for your fish.

Shatter-resistant Durable Quartz Glass Quartz glass carry an attractive appearance and durability. Quartz glass can be subject to greater temperature and pressure as compared to glass, and it won’t harm your fish and aquariums. |
Strong Grip Suction Cups The aquarium heaters can be installed and placed easily by two suction cups. The suction cups that fasten your aquarium heaters to your tank walls are essential to keeping your aquarium running smoothly. |
The Best Locations The best location to place a heater is near the water flow, such as the outlet (or inlet) from the filter, or in the stream of a power head. Because having water flowing directly past the heater more quickly and evenly disperses heated water throughout the tank. |
