Look at the Different Types of Fish Tank Heaters
There are several types of fish tank heaters that you may get, based upon exactly what aquarium setup you may have and what you really want. A specific variety is the immersible or hanging heater. This heater you hang from the rear of your tank. This kind of heater possesses a control that must stay above the level of the water, and so it has the potential to be problematic on occasion. These particular heaters also are often to the lower end of the price scale. Next you have the submersible heaters. Submersible heaters can be completely submerged in the aquarium water.
