Immersible Aquarium Heater
These are also called hanging on heaters, hanged on the top edge of your aquarium. One part of the heater contains a glass tube with a heating element that is dipped into the water. By the way, it is the most common type of heater.
Moreover, such kind of heaters also comes with new aquarium kits for beginners. It’s very affordable, you must buy one for your self, but there is one common issue, You must have an opening for it in your aquarium canopy to entertain it in your tank.
You must confirm that you have placed it correctly and your heater is working accurately or not. Sometimes in case of any vibrations or irregular movements can burst the glass tube or heater. Ultimately your heater will start burning itself, or your fish can get electric shocks too.
From my point of view, Never use such type of heater for marine or brackish water aquariums. They contain salts in water which will accumulate in the tube of the heater, they will lead to corrosion and finally resulting in electric shock. So proper care and monitoring are mandatory for them.
Submersible Aquarium Heater
As the name Shows clearly about its placement in your fish tank, These heaters are completely Submerged into your fish tank under the water level. You can place this type either vertically or horizontally.
Among all types, this one is the most common. It’s small and compact in size. You can easily identify this. It will look like a rod. Usually, they are enclosed into the glass tube with a coiled element to produce heat.
It is the best choice for those who are finding small fish tank heaters.
Place it just above the gravel so it would not touch your aquarium otherwise, your fish can even get caught between heater and glass, also, on the other hand, your heater glass can get cracks in it due to extreme heating.
Substrate Aquarium Heater
Such type is ideal when you have small space in your fish tank because this aquarium heater can be easily placed beneath the substrate. They are also called under gravel heaters. They are quite expensive, that’s why they are not as common as submersible heaters.
These heaters were used mostly in the 1990s for planted tank setups where they were used to promote moderate growth for the roots of aquatic plants.
In-filter Aquarium Heater
These types of heaters are placed inside the canister filter. When the water passes through the filter for filtration, it is cleaned as well as warmth. They are perfect for that aquarist who loves to keep aggressive fishes as these fishes fight with instruments as well. They are convenient and cost-effective; you are getting two tools in one.
Inline Aquarium Heater
These are placed outside in your fish tank, which needs the involvement of either a sump or a filter. Easily you can say that they are present between sump or the filter. Mostly they are chosen for large-sized aquariums Which prevent any possible contact between your lovely fish and heater. They are a bit difficult to setup.
In Sump Aquarium Heater
In Such type of heaters, the heaters are itself placed in the sump. You can say that they are the same as I mentioned above the inline heaters. But the only significant difference is maintenance. They are very easy to maintain than inline. These in sump heaters require enough space to be placed in your aquarium.
