Choosing The Right Aquarium Heater For Your Fish
Keeping your aquarium in optimum condition for your fish is a lot more difficult than most people imagine and ensuring the water is constantly at a temperature they can thrive in can be a challenge without a good quality aquarium heater.
Here’s some things you need to consider before making a purchase…
The most important thing of all is to work out the temperature your fish needs to thrive, because if they require a constant source of high quality heat – you’re going to need a very high quality heater.
Although we recommend the submersible heater, the most commonly used type of tank warmer, there are other versions which you may find more suitable for your needs. These are external, inline and substrate models.
Rather than being labeled as different sizes, heaters are generally categorised by the amount of watts they give out. The bigger your tank, the more watts you need.
The most popular kinds of heater are usually submersive, however some fish owners may be disappointed by the visual of a heater floating in their tank, which is what happens if you can’t get sucker cups to appropriately place your heater. You therefore might want to consider external or substrate heaters to not spoil the vision of your beautiful tank.
Automatic turn off
A great safety feature, this helps the tank stop from overheating by switching the heater off automatically when a desired temperature is reached, preventing it being heated constantly for long periods of time. Although not a necessity, it will certainly make your life easier.
A thermostat is pretty much a must when it comes to aquarium heaters, as it makes the process of changing the temperature far less complicated. These can often come with readable LED screens which constantly update you on the current temperature of the tank, so you can always keep on top of what’s going on.
Types of heater
A heater which needs to be fully submerged into the water to work, they can usually be placed vertically or horizontally within the tank. Submersible heaters are so popular because they work in both freshwater and saltwater tanks and can also efficiently heat all different sizes of tank.
External heaters are installed outside of the aquarium and often have a small hose as it’s heat source which hangs over the edge at the top of the tank. However due to this very reason they do not always distribute warmth so well. For small and medium sized tanks though they are a good option, as they don’t take up room in the small space you have.
Inline heaters are similar to external ones except they need to be attached to the tank filter system, heating water as it is pumped back in. This can make them fiddly and complicated to set up. They also may need additional parts for them to work properly.
If you’re looking for something a little more aesthetically pleasing, substrate heaters are often disguised as something like a rock, sea bedding or other sealife plant which can be heated via a cable hidden beneath the tank’s sandy base. However these aren’t particularly practical ways of heating an aquarium, and are quite rare.
