Aquarium Canister Filters for Beginners
Aquarium canister filters are needed in order to maintain the balance and cleanliness of the aquarium. This type of canister filters may be used for either a freshwater or saltwater aquarium. Depending on the type of canister filter, it may contain media that may filter the water through mechanical, chemical, or biological means.
When you look at the built and functions of the canister filter, these are quite similar to that of the ?hang on? filters. However, the canister filters are designed to provide more mechanical filtration compared with that of other filters. These filters are best used for aquaria that have fish types that tend to be messy eaters. Unlike most filters that are hung on the tank, canister filters are usually placed below the tank. At times, you might also find them inside the tank. For this type, the term ?submersible filter? is used. Some aquarium owners also choose to attach a wet-dry wheel to the outflow of the canister filter, which leads to the improvement of the biological filtration.
Most canister filters are designed to filter larger amounts of water compared with conventional water filters. These are also easily customized that you can specify if you would like the canister filter to have a mechanical, chemical, and biological functions. You may also ask for a canister filter that has bio wheels, UV sterilizers, or a water chiller.
The most noteworthy disadvantage of having a canister filter is the need to clean it frequently. Because this functions mainly as a mechanical filter, the debris from the water can easily clog it up. If you decide to submerge the water filter, clean up will get even more tedious than if the filter is located outside the aquarium. Despite the trouble in cleaning the filter, you have to do this often to prevent the decaying and toxic waste from coming back into the aquarium’s water.
Once the water has been freed from the chemicals, it is allowed to pass through the bacteria bed, wherein the bacteria present in the bed change the nitrites into nitrates. This biological filtration is necessary in order to lessen the toxic effects of these chemicals.
