Set Up Tips for a Canister Filter

When starting an aquarium, one of the most important decisions that must be made is what type of filter to use. A canister filter is a great option because it can hold as much as twice the amount of filter media as a power filter and it can be concealed under the tank rather than hang on the back of it. The set up for a canister filter may be a little more involved but it can go longer between cleanings than a power filter.

  1. Select the Right Location

    • While hang-on power filters are housed on the back of the tank and under-gravel filters are housed on the bottom of the aquarium, canister filters are only connected to the aquarium by two tubes and they can be stored in a much more discreet location. The best option is to purchase or build an aquarium cabinet that has storage space beneath the aquarium where you can house the canister filter as well as other aquarium supplies. If you do not have an aquarium cabinet be sure to at least store your canister filter somewhere that is easily accessible for cleaning and maintenance purposes.

    Purchase Supplies to Make Maintenance Easy

    • Most canister filter kits come with only the supplies needed to make the filter run -- if you want extras you will have to pay for them. Disconnect valves can be attached to the intake and output hoses to quickly cut off the water supply to allow for easy removal for cleaning and repair. Intake hose extensions and extractors make it possible for water to be drawn from the middle of the aquarium as well as from the surface or protein level.

    Keep Replacement Parts Handy

    • Depending on the size of your aquarium and your canister filter, you may need to replace cartridges, sponges, and filter media as often as once a week. When purchasing your canister filter, stock up on supplies and keep the extras on hand after you set up your filter for the first time. If you have a ready supply of the things you need you may be more likely to perform the routine changes and check-ups that will keep your canister filter running in top condition.

    Check the Filter Often to Prevent Clogs

    • As the canister filter sucks up dirt and debris, that debris will begin to clog the intake tube and reduce the water flow. To prevent this, check your canister filter often by taking apart the tubes, rinsing them out if necessary. Once a month or so you will need to completely disassemble the canister filter to check the impeller for clogs and to remove any build-up of algae, calcium, or salt on the tubes and canister chamber.
