Maintenance

Media

Look for Fully Customizable Canister Filters

These days most canister filters can be customized in various combinations so they can be set flexibly to deal predominantly with one type of media determined by you or an expert if you are not sure.

For example, if your pet fish produce ammonia in high levels, then this will have to be dealt with daily and as such media of the biological kind would be the media that you want to be most prominent like sponges and rings.

If your pet fish need really stable and clear water, you will need increased amounts of chemical media like resins or carbons. If your pet fish give out a lot of waste, you will need more media of the mechanical type which can be for example coarse pads you use in removing waste effectively.

It is good to remember that canister filters recommended for your aquarium size are offered in ranges. The bottom and of this range depicts the largest aquarium size that will be filtered effectively when the aquarium contains a large number of freshwater or saltwater fish.

The end of the range that is higher indicates the maximum aquarium size which can be filtered effectively with a small bioload and fish population.

Whatever canister filter you choose to be sure to consider whether you will be using freshwater or saltwater. This will have an overall effect on how often your canister filter needs to run and the predominant media it should be set.
