Recreate a tropical environment
The temperature of your fish tank is very important in order to keep your fish healthy. Fish can't regulate their own body temperature, so an aquarium heater is crucial in a tropical setup. This replicates their natural environment as much as possible, creating the best living conditions.
What are aquarium heaters?
Fish tank heaters make aquariums suitable for tropical fish that require warm waters to survive. While there are a few different ways that heaters function, some of which create different temperatures at different depths, all of them will heat your tank and can either be fitted with or feature a thermostat to avoid overheating your tank.
Why should I buy an aquarium heater?
If you want to run a tropical aquarium, a heater is a necessity, however, marine tanks should be monitored to ensure they are not becoming too hot or cold for their aquatic inhabitants - this can be done quite cheaply with an aquatic thermometer. Fish tank heaters are quite energy-efficient and can be made even more so with the use of a thermostat, which will ensure that the only time the aquarium is heated is when it falls below the required temperature.
What are the main types of aquarium heaters?
There are three main types of heater; submersible, substrate and filter heaters. Submersible models are placed in the aquarium and heat it in much the same way as a radiator heats a room. Substrate models are long cables that sit beneath the sand or gravel of the tank, stimulating plant growth as well as heating the water. Filter heaters are heaters that take water in, warm it and eject it to maintain a constant temperature across the whole tank.
What should I look for?
The best heaters on the market are energy-efficient and have built-in thermostats. Energy-efficient heaters are very inexpensive to run, cutting costs in the long run. The other important factor is the volume of water you need to heat as different heaters are capable of heating different amounts of water - check you will be able to heat your entire tank before making a purchase.
