Filtration in your fish tank is incredibly of import. Without proper filtration, debris and toxins can build up leading to devastating consequences for your fish. The importance of filtration might be clear, but what isn't, is how oft you should change your fish tank filter. The answer depends on which type of filter.

The actual filter itself – which holds the media – won't need replacing unless it stops working. Mechanical filter media volition not need replacing until it starts to fall autonomously (in fact, replacing it will do more harm than skilful), even so it will demand rinsing once every month or so in tank water. Chemical filters will need to be replaced about once per month. Biological filters won't demand replacing until they fall apart, but y'all will desire to rinse them once per month in tank water.

Mechanical Filters

Mechanical filters forcefulness the h2o through media such as a sponge to remove solid debris. This helps to go on your water clear and fish tank clean. The filter itself volition not demand replacing unless it stops working, and as long equally the filter media is non falling autonomously, it won't need replacing either.

In fact, in that location are negative consequences to replacing the media in a mechanical filter. Beneficial leaner that acts every bit a biological filter volition build up on the media, and replacing the media volition completely remove this bacteria from the tank.

Eventually the filter media will start to clog up and you lot will demand to rinse it. You lot should do this virtually once per month. Information technology's a practiced idea to combine this with a water change so you can use the tank h2o to rinse the media. This volition help to go along as much bacteria every bit possible on the media. You can also rinse it in conditioned h2o, merely practice not rinse in unconditioned tap water.

If the filter media starts to fall autonomously, it will demand replacing. When you start using the new media, exit the old media in the tank for a few weeks to requite the new media fourth dimension to build up bacteria.

Chemical Filters

Chemical filters are used to remove impurities from the h2o. Carbon is the nigh common media used. With chemical filters, the media adsorbs particles and will somewhen fill and become saturated. Chemical Filters will demand to be replaced about once per month, or at least once every ii months.

Biological Filters

Biological filtration occurs all over your fish tank. Beneficial bacteria breaks downward ammonia into nitrites, and then nitrites into nitrates which are much less toxic. This bacteria volition grow all over your fish tank, especially in the gravel and mechanical filter. You tin can besides purchase biological filters which just act as another place where bacteria can easily grow. You won't need to change a biological filter until it starts falling autonomously, but y'all might want to requite it a rinse in tank water every month or so.
