Aquarium Canister Filter Basics

Aquarium filters are necessary so that your aquarium will be free from the waste material that fish and marine animals give out as part of their biological processes. This device cleans the water in the aquarium through various means. Of the latest filter devices, the canister filter is one of those that can perform a number for functions so that a single device will be able to perform several clean-up tasks.

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.

Canister filters boast of their large water filtering capacity. Therefore, they can filter greater amounts of water than the power filters in the market. Canister filters also saves you space since you can hide it under your aquarium. These are also easy to customize so that you can have a combination of mechanical, chemical, and biological filter devices.

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.

Factors to consider when choosing filters

1. Availability of replacement parts

When shopping for a canister filter, you have to inquire if the store also carries replacement parts for the filter. Although the filter is durable and is guaranteed to last for a long time, there will be a time that you will have to change the parts of the canister filter as part of maintenance. It is best if you have spare o-rings, impellers, and rubber gaskets. You can?t be sure when you will need to replace them.

2. Are these the right ones for your aquarium type?

Before you purchase a canister filter, you have to inform the seller on whether you have a freshwater or a saltwater aquarium. There are canister filters that are not appropriate for saltwater and you have to clarify this before you close the sale.

3. Ease of installation and use

While someone can help you with installing the filter, most of the maintenance will be done by you. Check if you will be able to clean the device without help from an expert. The water filter is an important component of the aquarium. Once you have chosen a canister filter, learn the proper way to maintain it in order to prevent any danger from happening to your pets.
