Submersible Aquarium Heater

Why do I need an submersible aquarium heater and which one do I need to have? These are questions that every novice aquarist should ask because the water temperature of your tank is very important for the health and quality of life of your fish. Fish that come from tropical climates live in warm waters and the temperature has to be replicated in the fish tank they will inhabit. For this, you need some kind of heating. Most probably, you will need a submersible aquarium heater that you will place inside the tank.

When you decide what fish you want, do some research to find out the temperature range they will require. Some fish will do fine at room temperature, but if it varies greatly from Winter to Summer you will need to adjust accordingly. The submersible aquarium water heater size will depend on the size of your tank and the gallons of water it contains.
