What to consider when buying an external canister filter?

Decaying organic matter, dead plants, and external particles can deteriorate your water quality but this toxic element can be easily removed using an aquarium filter. There are many types of filters for your aquarium but today we’ll focus on the canister filters.

Canister filters are preferred for medium to large sized tanks due to their high volume filtration. They are commonly used as they save space inside the tank and as they are sealed the provide higher flow rates and more filtration stages compared to another type of filters. Canister filters can go up to 320 gallons per hours which means that they can filter your aquarium in way less time and eventually save you time and energy.

Keep in mind that if your inhabitants are quite small a canister filter may not be the best choice as they might be able to get sucked into the filter. When picking a canister filter it is vital to check their flow rate, either in LPH or GPH. Look for a well-designed motor that can be quiet when in use yet reliable and strong. Obviously, the choice of the motor will be determined by the size of your tank as you need to make sure that the canister filter is designed for the size of your tank.

Buy a filter from a reputable brand with a long period of warranty so as to make sure your aquarium is healthy and require minimal maintenance. Most models are easy to adapt to an aquarium and also easily adjusted to various tank sizes. If you want to know more about how actually the canister filter works here is you’ll enjoy.
