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.
The canister filters and the hang-on type of filters are comparable in the way they look and perform their functions. However, one of their major differences is that the canister filter may be placed in different locations in the aquarium. Aside from hanging the canister filter, it may also be placed below the aquarium, which will allow you to improve the aesthetic appeal of the aquarium. It may also be placed inside the aquarium. This type of water filter is also referred to as ?submersible filter.? Because of the improved filtration mechanisms of the canister filter, this is usually recommended for those aquariums that have messy eaters that tend to produce a lot of waste.
One of the best advantages of having a canister filter is that it has a larger capacity compared with other filters. Despite the large capacity, it is more compact so you can hide it from view, if you would like to. On the other hand, one of the disadvantages of using canister filters is that they have to be frequently cleaned. This is because the filtration relies on mechanical means. The filtration device will be easily clogged up by the filtered wastes and these have to be removed as soon as possible to prevent the decaying matter to come back into the water.
For this filter, the water is pumped at regular speeds into the filter. The filter usually performs its task using mechanical filters, such as a micron filter cartridge or glass wool. After the mechanical filtration stage, the water is then allowed to pass through different layers of media, including carbon and other absorbents. This will trap the odor, chlorine, ammonia, and other unnecessary chemicals that are in the water.
The canister filter has three types of filtration device. First, the water is allowed to pass the mechanical filter, which usually has the glass wool or the micron filter cartridge. This will filter the solid wastes in the water. Next, the water is subjected to chemical filtration by allowing it to pass through a layer of carbon. This will absorb the odor and chemicals such as ammonia and chlorine from the water. Biological filtration is the last step. Here, a mixture of bacteria is allowed to act on the nitrites that are in the water. These toxic chemicals are converted into nitrates, which are less toxic.
Guide to proper choice of canister filters
1. Replacement parts are readily available
After some time of use, you will have to replace some of the parts of your aquarium filter. You have to do this as soon as you detect a problem in order to prevent leaks that might threaten the lives of the fish and other animals in your aquarium. It is best if the store where you will get the filter also offers the replacement parts. Get some spare rubber gaskets and impellers and store them near your aquarium.
2. Are these the right ones for your aquarium type?
While there are canister filters that will work for both freshwater and saltwater, there are some that are not recommended for saltwater. Inform the seller what type of aquarium you have before buying one.
3. Are these easy to use?
While you can get someone to install the canister filter for you, it should be easy enough for you to operate without any help from an expert. Also, you have to make sure that during emergencies, you will be able to manipulate the filters to prevent any danger on your pets. Many hobbyists prefer getting canister filters because they are inexpensive and have a variety of functions. With sufficient information on how to use them, your aquatic pets will have a better aquarium environment.
