How to Find the Right Aquarium Canister Filters
Canister filters are essential 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 essential parts, and its function to decide what product to choose.
Here are some essential things to consider when finding the right canister filter:
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 engines are preferred more by fish keepers because they save space and make cleaning easier. Intake pumps are easily clogged, and clogging after some time is what you want to avoid.
Intake pumps, however, help you adjust the water flow quickly depending on what suits your desire. This is good for you if you know when to decrease or increase water flow, as increasing it most often affects the durability of the tank’s seal.
Canister filters can handle different water volumes, so you need to check your aquarium size; otherwise, you might compromise your water’s cleanliness. The product you choose must be compatible with your aquarium, as getting the incorrect one might cause the filter to break. This article specifies the gallon capacity of each canister filter to help you identify their compatibility with your aquarium.
When you’re choosing your canister filters, you can choose from among three filtration processes. This could be chemical, mechanical, or biological filtration. Some canisters use only two filter systems, while others have multi-stage filtration. Canister Filters with multi-stage filtrations are what you want to look for.
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.
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.
You would always need to maintain your canister filter to make it work effectively. Sometimes, there may be clogging, so you need to disassemble the product. With this, make sure you’re using a product you can efficiently work on and set up. Most canisters would provide you with manuals. You would want to make sure that the manuals are easy to understand to help in maintaining your canister filter’s productivity and efficiency.
