How to Find the Right Aquarium Canister Filters

Canister filters are important in keeping your aquarium water clean and pure. There are many canister filters and each of them may have different features. However, you need to know what a canister filter is, its important parts, and their function for you to discern well on what product to choose.

Here are some essential things to consider when finding the right canister filter:

Motor

Water flow in the aquarium is controlled by pumps present in the canister. Motors could either be internal while some canisters are fitted with an intake pump. Internal motors are preferred more by fish keepers because they save space and makes cleaning easier. Intake pumps easily clogged as well and clogging after a period of time is what you want to avoid.

Intake pumps, however, help you adjust the water flow easily depending on what suits your desire. This is good for you if you really know when to decrease or increase water flow, as increasing it most often affects the durability of the seal of the tank.

Aquarium Size

Canister filters can handle different water volumes, so you need to check your aquarium size, otherwise, you might be compromising the cleanliness of your water. The product you would choose must be compatible with your aquarium as getting the incorrect one might cause the filter to break.

The type of filter system your canister uses somehow dictates how well the aquarium is cleaned up. Chemical filtration would help in getting rid of toxic substances. Biological filtration gives way to the growth of good bacteria which would help your fish grow. Mechanical filtration sifts out dirt effectively. With all these three in your canister filter, a cleaner aquarium is assured.

Water Flow

The amount of water flow in an aquarium depends on the type of fish that you are keeping. Because of this, you need to check first if the water flow capacity of your canister filter is compatible with the fish in your aquarium. Water can flow from bottom to top or from top to bottom. Knowing this can help you decide on what canister filter to choose and how to maximize its benefits.
