Mechanical Filtration

In this case the filter will be packed With filter floss to extract particles of suspended solids and act as a pre-filter for reverse-flow systems and trickle filters To achieve a good through flow of water and extended media life, it is important to pack all materials fairly lightly. Depending on how heavily stocked the tank is, the filter media will need replacing every one to two weeks.

Chemical Filtration 

The canister filter should be packed with an adsorbative medium such as activated carbon or specific removal resin. This may act entirely independently or as a pre-filter to an ultra-Violet sterilizer, in which case the packing should include some filter floss just before the water return. The chemical medium should be contained in a nylon mesh bag specially made for the purpose, but if this is not available then it may be placed between two pieces of filter floss. If this latter method is used, then the filter floss will have to be changed once a week to prevent clogging and a restriction in water flow; some filters allow for packing in self-contained modules. Replace the filter medium every two . months in the case of carbon but follow manufacturer’s instructions with respect to resins and other filtration substances.

Biological Filtration

The filter should be packed with a porous material that is also fairly coarse and allows a good water flow. If flow is restricted in any way, the bacteria will begin to die. Encase the biological media in a nylon bag to prevent it being drawn into the pump motor impeller. As this type of filter must be disturbed as little as possible, it is not advisable to mix it with other media that requires regular attention, such as filter floss if the filter is large enough and stocking levels are kept reasonably low, it is possible to use a canister filter as the sole means of biological filtration, and to dispense with the undergravel media, gaining the tank valuable extra water volume.

This is not, however, to be recommended to the inexperienced unless under expert advice. It is vitally important that canister filters are packed fairly loosely and maintained properly to ensure that the correct amount of water reaches the pump impeller. If the impeller runs dry, irreparable damage can occur, or at the very least you will have clattenng, noisy units.

Always make sure canister filters are sited below the aquarium and not on the same level or above. This enables the syphon to work correctly. In an ideal world, the top of the canister should be just below the bottom of the tank the greater the distance below, the less water will be pumped due to back pressure. Equally, never use more hose than is absolutely necessary as increased back-pressure will reduce water flow and put an unnecessary strain on the pump. Friction will also cause much the same effect.

Clean inlet strainers and outlets once a week, or more often if required. All tubing should be cleared of obstructive algae and debris with a proprietary hose brush every three months. Lastly, do not underestimate the usefulness of the coarse pre-filter pad or ceramic pieces. These not only extract larger pieces of debris but also enable the pump to draw the water through the various media much more effectively. Never be tempted to dispense with the pre-filter stage to make. Space for other media.
