Heaters or 'Thermostats' are electrical pieces of equipment used to heat the water of aquariums to the desired minimum temperature.
1. Fish tank heaters come in various sizes and the choice of a particular size depends a lot on the amount of water inside the fish tank, size of the aquarium as well as the average temperature of the room. To calculate the ideal size of the heater, subtract the current room temperature from the required temperature. Also determine the size of the aquarium. With these two measurements, determining the ideal size of a heater should be easy. Generally, a 25-watt heater is great for a five gallon tank, 50-watt for a ten gallon tank and so on. Larger aquariums may require more than one heater and in such a case, the heaters should be placed on either side of the tank to ensure even distribution of heat.
These types of aquarium heaters are really popular with new betta owners. These “under the gravel” tank heaters are made specifically with small capacity aquariums in mind. Most of these mini heaters are heating rated up to about 5 gallons. That is to say, if you have an aquarium that is 5 gallons, you might be better off looking at a “real” in-tank heater like a preset or HOB heater. In any case, these little tank heaters do work and you should know they exist.
